Massive B-type pulsators in low-metallicity environments
C. Karoff, T. Arentoft, L. Glowienka +5
Massive B type pulsators such as beta Cep and slowly pulsating B (SPB) stars pulsate due to layers of increased opacity caused by partial ionization. The increased opacity blocks t…
Towards A Census of Earth-mass Exo-planets with Gravitational Microlensing
J. P. Beaulieu, E. Kerins, S. Mao +26
Thirteen exo-planets have been discovered using the gravitational microlensing technique (out of which 7 have been published). These planets already demonstrate that super-Earths (…
Discovery of a peculiar Cepheid-like star towards the northern edge of the Small Magellanic Cloud
J. B. Marquette, P. Tisserand, P. Francois +37
For seven years, the EROS-2 project obtained a mass of photometric data on variable stars. We present a peculiar Cepheid-like star, in the direction of the Small Magellanic Cloud,…
OGLE-2005-BLG-071Lb, the Most Massive M-Dwarf Planetary Companion?
Subo Dong, Andrew Gould, Andrzej Udalski +81
We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These…
Discovery of a Jupiter/Saturn Analog with Gravitational Microlensing
B. S. Gaudi, D. P. Bennett, A. Udalski +66
Searches for extrasolar planets have uncovered an astonishing diversity of planetary systems, yet the frequency of solar system analogs remains unknown. The gravitational microlens…
SPB stars in the open SMC cluster NGC 371
C. Karoff, T. Arentoft, L. Glowienka +5
Pulsation in beta Cep and SPB stars are driven by the kappa mechanism which depends critically on the metallicity. It has therefore been suggested that beta Cep and SPB stars shoul…
