Interferometric detections of sdO companions orbiting three classical Be stars
R. Klement, G. H. Schaefer, D. R. Gies +17
Classical Be stars are possible products of close binary evolution, in which the mass donor becomes a hot, stripped O or B-type subdwarf (sdO/sdB), and the mass gainer spins up and…
High Angular Resolution Astrophysics: Resolving Stellar Surface Features
Rachael M. Roettenbacher, Ryan P. Norris, Fabien Baron +9
We are now in an era where we can image details on the surfaces of stars. When resolving stellar surfaces, we see that every surface is uniquely complicated. Each imaged star provi…
The Expanding Fireball of Nova Delphini 2013
G. H. Schaefer, T. ten Brummelaar, D. R. Gies +34
A classical nova occurs when material accreting onto the surface of a white dwarf in a close binary system ignites in a thermonuclear runaway. Complex structures observed in the ej…
First astronomical unit scale image of the GW Ori triple. Direct detection of a new stellar companion
J. -P. Berger, J. D. Monnier, R. Millan-Gabet +17
Young and close multiple systems are unique laboratories to probe the initial dynamical interactions between forming stellar systems and their dust and gas environment. Their study…
Observations of DG Tauri with the Keck Interferometer
M. Colavita, R. Akeson, P. Wizinowich +1
We present the first science results from the Keck Interferometer, a direct-detection infrared interferometer utilizing the two 10-meter Keck telescopes. The instrument and system…
Radio and Infrared Properties of Dust-Enshrouded Wolf-Rayet Stars
J. D. Monnier, L. J. Greenhill, P. G. Tuthill +1
This paper discusses our ongoing efforts to characterize dust-enshrouded Wolf-Rayet (WR) stars in the radio and infrared. We have used the Very Large Array to measure the broadband…
