Variable Infrared Emission from the Supermassive Black Hole at the Center of the Milky Way
A. M. Ghez, S. A. Wright, K. Matthews +7
We report the detection of a variable point source, imaged at L'(3.8 microns) with the W. M. Keck II 10-meter telescope's adaptive optics system, that is coincident to within 18 ma…
Stellar Orbits Around the Galactic Center Black Hole
A. M. Ghez, S. Salim, S. D. Hornstein +5
We present new proper motion measurements and simultaneous orbital solutions for three newly identified (S0-16, S0-19, and S0-20) and four previously known (S0-1, S0-2, S0-4, and S…
The First Detection of Spatially Resolved Mid-Infrared Scattered Light from a Protoplanetary Disk
C. McCabe, G. Duchene, A. M. Ghez
We report spatially resolved 11.8 micron images, obtained at the W. M. Keck 10 m telescope, of the protoplanetary disk around the pre--main-sequence star HK Tau B. The mid-infrared…
No Fossil Disk in the T Tauri Multiple System V773 Tau
G. Duchene, A. M. Ghez, C. McCabe +1
We present new multi-epoch near-infrared and optical high-angular images of the V773 Tau pre-main sequence triple system, a weak-line T Tauri (WTTS) system in which the presence of…
Full Three Dimensional Orbits For Multiple Stars on Close Approaches to the Central Supermassive Black Hole
A. M. Ghez, E. Becklin, G. Duchene +4
With the advent of adaptive optics on the W. M. Keck 10 m telescope, two significant steps forward have been taken in building the case for a supermassive black hole at the center…
The First Measurement of Spectral Lines in a Short-Period Star Bound to the Galaxy's Central Black Hole: A Paradox of Youth
A. M. Ghez, G. Duchene, K. Matthews +11
We have obtained the first detection of spectral absorption lines in one of the high-velocity stars in the vicinity of the Galaxy's central supermassive black hole. Both Brgamma (2…
