The Be star omicron Cas is indeed the primary of a triple system
Petr Harmanec, Stephenson Yang, Miroslav Slechta +3
Analysis of radial velocities of two narrow absorption components in the Mg II 4481 A line demonstrated that the secondary of the Be star omicron Cas is indeed a close binary syste…
Dangerous Questions in Astronomy Education
Michael Fitzgerald, Rachel Freed, Dan Reichart +63
As astronomy enters an era defined by global telescope networks, petabyte-scale surveys, and powerful computational tools, the longstanding goals of astronomy education, particular…
The Hot Companion and Circumbinary Disk of the Be Star HR 2142
Geraldine J. Peters, Luqian Wang, Douglas R. Gies +1
We present a spectroscopic investigation of the Be+sdO binary system HR 2142 that is based upon large sets of ultraviolet observations from the International Ultraviolet Explorer a…
Spectral and spatial imaging of the Be+sdO binary phi Persei
D. Mourard, J. D. Monnier, A. Meilland +25
The rapidly rotating Be star phi Persei was spun up by mass and angular momentum transfer from a now stripped-down, hot subdwarf companion. Here we present the first high angular r…
A CHARA Array Survey of Circumstellar Disks around Nearby Be-type Stars
Y. Touhami, D. R. Gies, G. H. Schaefer +11
We report on a high angular resolution survey of circumstellar disks around 24 northern sky Be stars. The K-band continuum survey was made using the CHARA Array long baseline inter…
FUV Detection of the Suspected Subdwarf Companion to the Be Star 59 Cygni
Geraldine J. Peters, Tiffany D. Pewett, Douglas R. Gies +2
We report on the detection of a hot subdwarf component in the Be binary system, 59 Cygni. The spectral signature is found in cross-correlation functions of photospheric model spect…
