The Palomar/Keck Adaptive Optics Survey of Young Solar Analogs: Evidence for a Universal Companion Mass Function (2009)

Metchev, Stanimir A., Hillenbrand, Lynne A.

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 3 Myr-3 Gyr age range with distances of 10-190...

A cross-match of 2MASS and SDSS: newly found L and T dwarfs and an estimate of the space density of T dwarfs (2008)

Metchev, Stanimir A., Kirkpatrick, J. Davy, Berriman, G. Bruce, Looper, Dagny

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 for object detection...

The moth : an unusual circumstellar structure associated with HD 61005 (2007)

Hines, Dean C., Schneider, Glenn, Hollenbach, David, Mamajek, Eric E., Hillenbrand, Lynne A., Metchev, Stanimir A., ...

We present the discovery of an unusual spatially resolved circumstellar structure associated with the ≈90 Myr, nearby, G dwarf star HD 61005. Observations from the FEPS Spitzer Legacy Science...

First High-Contrast Science with an Integral Field Spectrograph: the Sub-Stellar Companion to GQ Lup (2006)

McElwain, Michael W., Metchev, Stanimir A., Larkin, James E., Barczys, Matthew, Iserlohe, Christof, Krabbe, Alfred, ...

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 studying faint...

HD 203030B: an Unusually Cool Young Sub-Stellar Companion near the L/T Transition (2006)

Metchev, Stanimir A., Hillenbrand, Lynne A.

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 estimated mass of 0.023...

Adaptive optics imaging of the AU Microscopii circumstellar disk: Evidence for dynamical evolution (2005)

Metchev, Stanimir A., Eisner, Joshua A., Hillenbrand, Lynne A., Wolf, Sebastian

We present an H-band image of the light scattered from circumstellar dust around the nearby (10 pc) young M star AU Microscopii (AU Mic, GJ 803, HD 197481), obtained with the Keck adaptive optics...

Initial Results from the Palomar Adaptive Optics Survey of Young Solar-Type Stars: a Brown Dwarf and Three Stellar Companions (2004)

Metchev, Stanimir A., Hillenbrand, Lynne A.

We present first results from the Palomar Adaptive Optics Survey of Young Stars conducted at the Hale 5 m telescope. Through direct imaging we have discovered a brown dwarf and two low-mass stellar...

Ten-Micron Observations of Nearby Young Stars (2003)

Metchev, Stanimir A., Hillenbrand, Lynne A., Meyer, Michael R.

(abridged) We present new 10-micron photometry of 21 nearby young stars obtained at the Palomar 5-meter and at the Keck I 10-meter telescopes as part of a program to search for dust in the habitable...

A two-dimensional Kolmogorov-Smirnov test for crowded field source detection: ROSAT sources in NGC 6397 (2002)

Metchev, Stanimir A., Grindlay, Jonathan E.

We present a two-dimensional version of the classical one-dimensional Kolmogorov-Smirnov (K-S) test, extending an earlier idea due to Peacock (1983) and an implementation proposed by Fasano &...
