Formation and Evolution of Planetary Systems (FEPS): Primordial Warm Dust Evolution From 3-30 Myr around Sun-like Stars

M. D. Silverstone, M. R. Meyer, E. E. Mamajek +14

We present data obtained with the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope (Spitzer) for a sample of 74 young (t < 30 Myr old) Sun-like (0.7 < M(star)/M(Sun)…

The Age of AB Dor

K. L. Luhman, John R. Stauffer, E. E. Mamajek

We have derived a new age estimate for the nearby young star AB Dor and have investigated the resulting implications for testing theoretical evolutionary models with the data repor…

The Formation and Evolution of Planetary Systems (FEPS): Discovery of an Unusual Debris System Associated with HD 12039

D. C. Hines, D. E. Backman, J. Bouwman +17

We report the discovery of a debris system associated with the Myr old G3/5V star HD 12039 using {\it Spitzer Space Telescope} observations from 3.6 -- 160m. An observ…

A Moving Cluster Distance to the Exoplanet 2M1207 B in the TW Hya Association

Eric E. Mamajek

A candidate extrasolar planet companion to the young brown dwarf 2MASSW J1207334-393254 (2M1207) was recently discovered by Chauvin et al. They find that 2M1207 B's temperature and…

Formation and Evolution of Planetary Systems: Upper Limits the Gas Mass in HD105

D. Hollenbach, U. Gorti, M. Meyer +13

We report infrared spectroscopic observations of HD 105, a nearby ( pc) and relatively young ( Myr) G0 star with excess infrared continuum emission, which has bee…
