Multiple protostellar systems. II. A high resolution near-infrared imaging survey in nearby star-forming regions
G. Duchêne, S. Bontemps, J. Bouvier +3
(abridged) Our project endeavors to obtain a robust view of multiplicity among embedded Class I and Flat Spectrum protostars in a wide array of nearby molecular clouds to disentang…
Measuring the Mass of a Pre-Main Sequence Binary Star Through the Orbit of TWA 5A
Q. M. Konopacky, A. M. Ghez, G. Duchene +2
We present the results of a five year monitoring campaign of the close binary TWA 5Aab in the TW Hydrae association, using speckle and adaptive optics on the W.M. Keck 10 m telesco…
Photometric Stellar Variability in the Galactic Center
M. Rafelski, A. M. Ghez, S. D. Hornstein +2
We report the results of a diffraction-limited, photometric variability study of the central 5"x5" of the Galaxy conducted over the past 10 years using speckle imaging techniques o…
Investigating disk evolution: A high spatial resolution mid-infrared survey of T Tauri stars
C. McCabe, A. M. Ghez, L. Prato +3
We present a high spatial resolution, 10-20 micron survey of 65 T Tauri binary stars in Taurus, Ophiuchus, and Corona Australis using the Keck 10 m telescopes. Designed to probe th…
An Adaptive Optics Survey for Companions to Stars with Extra-Solar Planets
J. P. Lloyd, M. C. Liu, J. R. Graham +12
We have undertaken an adaptive optics (AO) imaging survey of extrasolar planetary systems and stars showing interesting radial velocity trends from high precision radial velocity s…
Young Binary Stars and Associated Disks
Robert D. Mathieu, Andrea M. Ghez, Eric L. N. Jensen +1
The typical product of the star formation process is a binary star. Binaries have provided the first dynamical measures of the masses of pre-main-sequence (PMS) stars, providing su…
