Milliarcsecond N-Band Observations of the Nova RS Ophiuchi: First Science with the Keck Interferometer Nuller
R. K. Barry, W. C. Danchi, W. A. Traub +38
We report observations of the nova RS Ophiuchi (RS Oph) using the Keck Interferometer Nuller (KIN), approximately 3.8 days following the most recent outburst that occurred on 2006…
Near-Infrared Interferometric, Spectroscopic, and Photometric Monitoring of T Tauri Inner Disks
J. A. Eisner, L. A. Hillenbrand, R. J. White +3
We present high angular resolution observations with the Keck Interferometer, high dispersion spectroscopic observations with Keck/NIRSPEC, and near-IR photometric observations fro…
Dynamical Masses for Pre-Main Sequence Stars: A Preliminary Physical Orbit for V773 Tau A
A. F. Boden, G. Torres, A. I. Sargent +9
We report on interferometric and radial-velocity observations of the double-lined 51-d period binary (A) component of the quadruple pre-main sequence (PMS) system V773 Tau. With th…
Spectrally Dispersed K-Band Interferometric Observations of Herbig Ae/Be Sources: Inner Disk Temperature Profiles
J. A. Eisner, E. I. Chiang, B. F. Lane +1
We use spectrally dispersed near-IR interferometry data to constrain the temperature profiles of sub-AU-sized regions of 11 Herbig Ae/Be sources. We find that a single-temperature…
No Expanding Fireball: Resolving the Recurrent Nova RS Ophiuchi with Infrared Interferometry
J. D. Monnier, R. K. Barry, W. A. Traub +17
Following the recent outburst of the recurrent nova RS Oph on 2006 Feb 12, we measured its near-infrared size using the IOTA, Keck, and PTI Interferometers at multiple epochs. The…
The Circumstellar Environments of Young Stars at AU Scales
Rafael Millan-Gabet, Fabien Malbet, Rachel Akeson +3
We review recent advances in our understanding of the innermost regions of the circumstellar environment around young stars, made possible by the technique of long baseline interfe…
