Variable Stars in the Lepine List of Nearby Stars
Abstract
An analysis of Lepine’s list (2005, AJ 130, 1680) of newly identified nearby stars was conducted at the Pisgah Astronomical Research Institute in Rosman, NC in hopes of supporting future searches for potential hosts for nearby, extraterrestrial planets. The celestial coordinates were extracted from Lepine’s list and cross-referenced with the Northern Sky Variability Survey to determine which stars among them were variable. The stars deemed variable were then cross referenced with the ROSAT all sky survey to determine if any were X-ray sources. It was determined that roughly half of the list of newly discovered nearby stars coincided to within 3arcseconds of a NSVS variable. The search done with the ROSAT all sky survey is, at this point, being verified. Future work will include statistical studies of the sample and follow-up observations of candidate variable stars. We would like to acknowledge support for this work for one of us (McNutt) through 2006 PARSEC Internship Program, and was supported by NASA Award NNG05GQ66, the North Carolina Space Grant, and the Glaxo-Wellcome Endowment at UNCA.
