MOST satellite photometry of stars in the M67 field: Eclipsing binaries, blue stragglers and delta-Scuti variables
Theodor Pribulla, Slavek Rucinski, Jaymie M. Matthews +7
We present two series of MOST (Microvariability & Oscillations of STars) space-based photometry, covering nearly continuously 10 days in 2004 and 30 days in 2007, of selected varia…
Direct spectroscopic observations of clumping in O-star winds
Sebastien Lepine, Anthony F. J. Moffat
We report the detection and monitoring of transient substructures in the radiation-driven winds of five massive, hot stars in different evolutionary stages. Clumping in the winds o…
MOST detects SPBe pulsations in HD 127756 & HD 217543: Asteroseismic rotation rates independent of vsini
C. Cameron, H. Saio, R. Kuschnig +7
The MOST (Microvariability and Oscillations of Stars) satellite has discovered SPBe (Slowly Pulsating Be) oscillations in the stars HD 127756 (B1/B2 Vne) and HD 217543 (B3 Vpe). Fo…
Discovery of the strongly eccentric, short-period binary nature of the B-type system HD 313926 by the MOST satellite
Slavek Rucinski, Rainer Kuschnig, Jaymie M. Matthews +7
The MOST photometric space mission discovered an eclipsing binary among its guide stars in June 2006 which combines a relatively large eccentricity e = 0.20 with an orbital period…
The Gemini Deep Planet Survey -- GDPS
David Lafreniere, Rene Doyon, Christian Marois +10
We present the results of the Gemini Deep Planet Survey, a near-infrared adaptive optics search for giant planets and brown dwarfs around nearby young stars. The observations were…
MOST Detects g-Modes in the Late-Type be Star beta CMi (B8Ve)
H. Saio, C. Cameron, R. Kuschnig +10
The Microvariability and Oscillations of stars (MOST) satellite has detected low-amplitude light variations (1 mmag) in the Be star CMi (B8Ve). The observations lasted…
