NASA, Exoplanets, and Life After NMSU

Dawn Gelino, NASA Exoplanet Science Institute, CalTech

Abstract:  Are you interested in learning more about the search for life in the Universe? Or perhaps you may be interested in being awarded time on 10 m telescopes for your science? Or maybe you are ready to learn more about prestigious NASA Postdoctoral Fellowships? This talk will touch on some recent and exciting results in the exoplanet field, as well as the different NASA HQ programs that I currently run for all of astrophysics (many of which may be helpful and applicable to YOU), and the path I took from NMSU to where I am now.

Stellar Winds and Stellar Rotation

Don Terndrup, Ohio State University

For more than 50 years, we have known that stars rotate quickly when they are young and slow down as they age.  This process gives us important clues about magnetic field strength and geometry, as well as the nature of stellar winds, in solar-like stars.  We have been working to put the analysis of stellar rotation on a modern statistical footing, and in this talk I will give you an update on our efforts.  There are a number of critical observational problems that must be considered in calibrating models of angular momentum loss, especially problems of data censorship (older or less active stars are not detected in studies of rotation).  I will conclude by evaluating the prospects for using stellar rotation as an age indicator, and demonstrate that such ages are far less precise – though still useful – than our group and others have previously claimed.
