Dan Cohen AUTHOR San Antonio officials believe the $5 million grant the region was awarded Thursday by the state to connect the area’s military installations to a backup water source will go a long way toward ensuring the viability of the area’s military installations over the coming decades.The Texas Military Preparedness Commission (TMPC) awarded the grant as part of $15 million in funding it plans to disburse this year under the state’s Defense Economic Adjustment Assistance Grant program to help communities support local installations.Bob Murdock, director of San Antonio’s Office of Military Affairs, said the award is critical for the future growth of Joint Base San Antonio (JBSA), which is made up of Fort Sam Houston, Lackland Air Force Base and Randolph AFB.“It addresses Joint Base San Antonio’s top priority and I believe having access to an alternative water source makes JBSA significantly more competitive to garner additional missions when there is a future BRAC,” Murdock said.JBSA is currently under a drought warning, said Tim Trevino, senior director of strategic planning and communications for the Alamo Area Council of Governments (AACOG), which applied to the state commission for the money on behalf of the region.The situation is most critical at Camp Bullis — a training reservation attached to Fort Sam Houston — which relies on an aquifer that is susceptible to drought.San Antonio’s grant will go toward an $11 million-plus project to construct four miles of pipeline to provide an alternative water source for Fort Sam Houston; Camp Bullis; Lackland; and two individual sites at Lackland, the Medina Annex and Security Hill. Randolph already has a backup water source.The project calls for the San Antonio Water System to extend water mains and other equipment to the fence lines at each of those five sites, said Trevino. The project also will cover work inside the fence line at Camp Bullis, he said, requiring the Air Force to formally accept a gift from the local government. The Army, however, would be responsible for the labor at Bullis.The project is scheduled to be completed by August 2017, Trevino told 360.In a written statement commenting on Thursday’s award, Diane Rath, AACOG’s executive director, thanked Texas Gov. Greg Abbott (R), the commission and local stakeholders.“This is truly a community and statewide effort, including the governor and the TMPC commissioners, and I could not think of a more exciting mission than to help secure our bases’ military missions. This couldn’t have been done without our state and local community partners, and this is truly a regional project that will be beneficial for communities throughout our surrounding counties,” Rath said.See Monday’s 360 for details about the other communities that received awards from the Texas Military Preparedness Commission.

(Phys.org)—New research conducted by a team of astronomers, led by Simone Scaringi of the Max Planck Institute for Extraterrestrial Physics in Germany, examines peculiar dimming of a newly found young stellar object designated EPIC 204278916. The study tries to explain the nature of these dipping events observed in the object’s light curve. The results were published Aug. 25 in a paper available on arXiv.org.

More information: The peculiar dipping events in the disk-bearing young-stellar object EPIC 204278916, arXiv:1608.07291 [astro-ph.SR] arxiv.org/abs/1608.07291AbstractEPIC 204278916 has been serendipitously discovered from its K2 light curve which displays irregular dimmings of up to 65% for ~25 consecutive days out of 78.8 days of observations. For the remaining duration of the observations, the variability is highly periodic and attributed to stellar rotation. The star is a young, low-mass (M-type) pre-main-sequence star with clear evidence of a resolved tilted disk from ALMA observations. We examine the K2 light curve in detail and hypothesise that the irregular dimmings are caused by either a warped inner-disk edge or transiting cometary-like objects in either circular or eccentric orbits. The explanations discussed here are particularly relevant for other recently discovered young objects with similar absorption dips. EPIC 204278916 light curve. The system was observed for over 78.8 days at 29.4 minute cadence. The units on the y-axis are electrons/second, and can be converted to Kepler magnitudes Kp using the conversion found in the Kepler Instrument Handbook.

Credit: Scaringi et al., 2016. © 2016 Phys.org EPIC 204278916, is a young, pre-main-sequence star, about 5 million years old, of spectral type M1, located in the Upper Scorpius sub-group of the Scorpius-Centaurus OB association. It is the size of our sun in diameter, but has only 0.5 solar masses. This young stellar object was discovered by NASA Kepler spacecraft’s prolonged mission known as K2, during its Campaign 2 between Aug. 23 and Nov. 13, 2014. Moreover, follow-up observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile revealed that EPIC 204278916 also has a resolved tilted disk.In a recent paper, Scaringi and his colleagues analyze the data provided by K2 and ALMA regarding EPIC 204278916, available in the Ecliptic Plane Input Catalog (EPIC) and the Mikulski Archive for Space Telescope (MAST) archive, with the aim to examine the object’s light curve and its irregular dimmings in detail.”We examine the K2 light curve in detail and hypothesize that the irregular dimmings are caused by either a warped inner-disk edge or transiting cometary-like objects in either circular or eccentric orbits,” the researchers wrote in the paper.According to the data provided by K2, EPIC 204278916 exhibited irregular dimmings of up to 65 percent for about 25 consecutive days out of 79 days of observations. The researchers also noted that when it comes to the remaining days of observation, this variability is highly periodic and could be attributed to stellar rotation.One of the two most plausible explanations offered by the astronomers to explain the irregular dips in the object’s light curve is that they are caused by non-axisymmetric structures in the inner disk edge occulting EPIC 204278916. Due to the fact that these dimmings are at a level of up to 65 percent, the occulting material must have a large scale height comparable to the size of the object.The researchers also noted that the dips in young stellar objects like EPIC 204278916 might be caused by transiting circumstellar objects. They emphasized that if transiting cometary-like bodies are responsible for the observed dips, the events are most likely occurring close to periastron passage.However, more observations are definitely needed to fully understand the mysterious behavior of EPIC 204278916. Moreover, further continuous photometric and spectroscopic monitoring of this system for subsequent dipping events will help determine whether this behavior is periodic or not.”It is clear that further observations of EPIC 204278916 and other young stellar object dippers will be required in the future, both photometric and spectroscopic, in order to establish their true origin. In particular, it is important to determine whether the observed dips in the K2 light curve of EPIC 204278916 are observed again, in which case infer their recurrence timescale and spectroscopic properties,” the team concluded.The researchers could soon get the opportunity to revisit EPIC 204278916, as in 2017 the K2 mission could re-observe the Scorpius-Centaurus OB association during the planned Campaign 15.

JON Wilkin says attention to detail will ultimately decide the destination of the World Club Challenge.Saints’ captain has been at the forefront of his side’s perfect start to the Super League season.But that will count for nothing when they take on the South Sydney Rabbitohs at Langtree Park this Sunday.“We have two wins under our belts and have played ok apart from in our first pre-season game,” Wilkin said. “We are happy with some elements of our game and we certainly need did well Salford.“What I am confident in though is we need to be much better than we have been so far to come close to South Sydney.“If we give South Sydney as much possession as we have given other sides in the opening two rounds then they will punish us a lot more ruthlessly than we have been. We are aware of that and have some easy improvements to make.“Our defence has been exceptional from the back end of last year to the start of this. Most attention has gone into that in the off season. Sean Long and Jamahl Lolesi are smart coaches and they have helped us improve dramatically in that area.“That doesn’t guarantee a good night on Sunday – we have to work hard and take that into the game.“We’ve started well and haven’t conceded a lot of points. The cornerstone of any side that wants to win trophies is defence. If you are loose defensively you are liable to be beaten in the big games. I don’t think us or Souths could be called loose in defence.”He continued: “The experience of winning in 2007 (against Brisbane) is something we can use. Having something to draw on, good or bad, is a good learning experience. To beat Brisbane was one of the proudest moments of my life.“Now as captain, leading Saints out into a sell-out Langtree Park, against South Sydney – that will be a special night in my career and something I will be reflecting on after the game. But first we’re all focused on producing a spot on performance on Sunday.“The atmosphere will be special and vibrant. We can’t wait.”
