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…
Low-mass companions to Hyades stars
E. W. Guenther, D. B. Paulson, W. D. Cochran +3
It is now well established that a large fraction of the low-mass stars are binaries or higher order multiples. Similarly a sizable fraction have giant planets. In contrast to these…
Mid Infrared Observations of Van Maanen 2: No Substellar Companion
J. Farihi, E. E. Becklin, B. A. Macintosh
The results of a comprehensive infrared imaging search for the putative 0.06 solar mass astrometric companion to the 4.4 pc white dwarf van Mannen 2 are reported. Adaptive optics i…
Characterizing the Adaptive Optics Off-Axis Point-Spread Function - I: A Semi-Empirical Method for Use in Natural-Guide-Star Observations
E. Steinbring, S. M. Faber, S. Hinkley +11
Even though the technology of adaptive optics (AO) is rapidly maturing, calibration of the resulting images remains a major challenge. The AO point-spread function (PSF) changes qu…
