These are the papers we have discussed in past AstroCoffee/Lunch meetings.
AstroLunch: October 16, 2012
Dr. Amy Kimball from the National Radio Astronomy Observatory (NRAO) will be giving a presentation on her research entitled "The Radio Luminosity Function of Optically Selected QSOs: Star Formation and AGN."
AstroLunch: November 6, 2012
Dr. Amy Winebargar from NASA's Marshall Space Flight Center will be giving a presentation on her research entitled "A New View of the Sun." The abstract is as follows: "The recent launch of the High-Resolution Coronal Imager (Hi-C) as a sounding rocket has offered a new, different view of the Sun. With ~ 0.2" resolution and 5 second cadence, Hi-C reveals dynamic, small-scale structure within a complicated active region, including coronal braiding, reconnection regions, cool, evolving structures, and flows along active region fans. By combining this data set with the Solar Dynamics Observatory's (SDO) Atmospheric Imaging Array (AIA) and Helioseismic and Magnetic Imager (HMI) and Hinode's X-ray Telescope (XRT) and Extreme-ultraviolet Imaging Spectrograph (EIS), we have compiled a rich data set which can be used to address many outstanding questions in solar physics. Though the Hi-C rocket flight was short (only 5 minutes), the added insight of the small-scale structure gained from the Hi-C data allows us to look at this active region (+- 1 day of flight) and other active regions with new understanding."
AstroLunch: November 13, 2012

Special Visitor Talk: Spectra of Transiting Extrasolar Planets: Past, Present, and Future
by Peter R. McCullough
We review observational spectra of the atmospheres of a few transiting extrasolar planets. We begin with results from years past, such as HST NICMOS infrared spectra of HD 189733b and XO-1b. We continue to present-day HST WFC3 spectra of the same two planets, made with a newly-reintroduced technique of spatial scanning of the telescope. With regard to XO-1's infrared spectrum, as they say in finance, "past results do not guarantee future performance." On the other hand, with the spatial-scanning technique, we do confirm the flat spectrum of the super-Earth GJ 1214b (Berta et al. 2012). We discuss similar observations that could be made in the future with HST, JWST, and other telescopes. We conclude by summarizing the Transiting Exoplanet Survey Satellite, TESS, which will discover the nearest rocky exoplanets, those most interesting and most suitable for follow-up characterization of the sort we have presented.
