One or more bound planets per Milky Way star from microlensing observations
A. Cassan, D. Kubas, J. -P. Beaulieu +39
Most known extrasolar planets (exoplanets) have been discovered using the radial velocity or transit methods. Both are biased towards planets that are relativ…
MOA-2009-BLG-387Lb: A massive planet orbiting an M dwarf
Virginie Batista, A. Gould, S. Dieters +25
We report the discovery of a planet with a high planet-to-star mass ratio in the microlensing event MOA-2009-BLG-387, which exhibited pronounced deviations over a 12-day interval,…
Limits on additional planetary companions to OGLE-2005-BLG-390L
D. Kubas, A. Cassan, M. Dominik +1
We investigate constraints on additional planets orbiting the distant M-dwarf star OGLE-2005-BLG-390L, around which photometric microlensing data has revealed the existence of the…
Discovery of Five New R Coronae Borealis Stars in the MACHO Galactic Bulge Database
A. Zaniewski, Geoffrey C. Clayton, D. L. Welch +3
We have identified five new R Coronae Borealis (RCB) stars in the Galactic bulge using the MACHO Project photometry database, raising the total number of known Galactic RCB stars t…
The MACHO Project Large Magellanic Cloud variable star inventory. XI. Frequency analysis of the fundamental mode RR Lyrae stars
C. Alcock, D. R. Alves, A. Becker +20
We have frequency analyzed 6391 variables classified earlier as fundamental mode RR Lyrae (RR0) stars in the MACHO database on the Large Magellanic Cloud (LMC). The overwhelming ma…
The unusual optical afterglow of the gamma-ray burst GRB 021004: Color changes and short-time-scale variability
D. Bersier, K. Z. Stanek, J. Winn +11
We report UBVRI observations of the optical afterglow of the gamma-ray burst GRB 021004. We observed significant (10-20%) deviations from a power law decay on several time scales,…
