Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
Asteroseismology of red giants from the first four months of Kepler data: Fundamental parameters
T. Kallinger, B. Mosser, S. Hekker +18
Clear power excess in a frequency range typical for solar-type oscillations in red giants has been detected in more than 1000 stars, which have been observed during the first 138 d…
The gamma-ray binary LS 5039: mass and orbit constraints from MOST observations
Gordon E. Sarty, Tamas Szalai, Laszlo L. Kiss +12
The results of a coordinated space-based photometric and ground-based spectroscopic observing campaign on the enigmatic gamma-ray binary LS 5039 are reported. Sixteen days of obser…
Analysis of variability of TW Hya as observed by MOST and ASAS in 2009
Michal Siwak, Slavek M. Rucinski, Jaymie M. Matthews +6
As a continuation of our previous studies in 2007 and 2008, new photometric observations of the T Tauri star TW Hya obtained by the MOST satellite and the ASAS project over 40 days…
Analysis of the MOST light curve of the heavily spotted K2IV component of the single-line spectroscopic binary II Pegasi
Michal Siwak, Slavek M. Rucinski, Jaymie M. Matthews +5
Continuous photometric observations of the visible component of the single-line, K2IV spectroscopic binary II Peg carried out by the MOST satellite during 31 consecutive days in 20…
Searching for Trojan Asteroids in the HD 209458 System: Space-based MOST Photometry and Dynamical Modeling
Reka Moldovan, Jaymie M. Matthews, Brett Gladman +2
We have searched Microvariability and Oscillations of STars (MOST) satellite photometry obtained in 2004, 2005, and 2007 of the solar-type star HD 209458 for Trojan asteroid swarms…
