The Full Spectrum Galactic Terrarium: MHz to TeV Observations of Various Critters
Mallory S. E. Roberts, C. Brogan, S. Ransom +13
Multi-wavelength studies at radio, infrared, optical, X-ray, and TeV wavelengths have discovered probable counterparts to many Galactic sources of GeV emission detected by EGRET. T…
A Spectroscopic Orbit for Regulus
D. R. Gies, S. Dieterich, N. D. Richardson +8
We present a radial velocity study of the rapidly rotating B-star Regulus that indicates the star is a single-lined spectroscopic binary. The orbital period (40.11 d) and probable…
Detection of a Hot Subdwarf Companion to the Be Star FY Canis Majoris
Geraldine J. Peters, Douglas R. Gies, Erika D. Grundstrom +1
The rapid rotation of Be stars may be caused in some cases by past mass and angular momentum accretion in an interacting binary in which the mass donor is currently viewed as a sma…
The B and Be Star Population of NGC 3766
M. Virginia McSwain, Wenjin Huang, Douglas R. Gies +2
We present multiple epochs of H-alpha spectroscopy for 47 members of the open cluster NGC 3766 to investigate the long term variability of its Be stars. Sixteen of the stars in thi…
A Spectroscopic Study of Mass Outflows in the Interacting Binary RY Scuti
E. D. Grundstrom, D. R. Gies, T. C. Hillwig +5
The massive interacting binary RY Scuti is an important representative of an active mass-transferring system that is changing before our eyes and which may be an example of the for…
Radial Velocities of Six OB Stars
T. S. Boyajian, D. R. Gies, E. K. Baines +7
We present new results from a radial velocity study of six bright OB stars with little or no prior measurements. One of these, HD 45314, may be a long-period binary, but the veloci…
