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…
