The Palomar/Keck Adaptive Optics Survey of Young Solar Analogs: Evidence for a Universal Companion Mass Function
Stanimir Metchev, Lynne Hillenbrand
We present results from an adaptive optics survey for substellar and stellar companions to Sun-like stars. The survey targeted 266 F5-K5 stars in the 3Myr to 3Gyr age range with di…
A Cross-Match of 2MASS and SDSS: Newly-Found L and T Dwarfs and an Estimate of the Space Densitfy of T Dwarfs
Stanimir Metchev, J. Davy Kirkpatrick, G. Bruce Berriman +1
We report new L and T dwarfs found in a cross-match of the SDSS Data Release 1 and 2MASS. Our simultaneous search of the two databases effectively allows us to relax the criteria f…
The Formation and Evolution of Planetary Systems: Placing Our Solar System in Context with Spitzer
Michael R. Meyer, Lynne A. Hillenbrand, Dana Backman +32
We provide an overview of the Spitzer Legacy Program ``Formation and Evolution of Planetary Systems" (FEPS) which was proposed in 2000, begun in 2001, and executed aboard the Spitz…
First High-Contrast Science with an Integral Field Spectrograph: the Sub-Stellar Companion to GQ Lup
Michael W. McElwain, Stanimir A. Metchev, James E. Larkin +6
We present commissioning data from the OSIRIS integral field spectrograph (IFS) on the Keck II 10 m telescope that demonstrate the utility of adaptive optics IFS spectroscopy in st…
Integrated Light 2MASS IR Photometry of Galactic Globular Clusters
Judith G. Cohen, Scott Hsieh, Stanimir Metchev +2
We have mosaiced 2MASS images to derive surface brightness profiles in JHK for 104 Galactic globular clusters. We fit these with King profiles, and show that the core radii are ide…
HD 203030B: an Unusually Cool Young Sub-Stellar Companion near the L/T Transition
Stanimir A. Metchev, Lynne A. Hillenbrand
We present the discovery of a brown-dwarf companion to the 130-400 Myr-old G8 V star HD 203030. Separated by 11.9" (487 AU in projection) from its host star, HD 203030B has an esti…
