Studying the Galactic Bulge Through Spectroscopy of Microlensed Sources: I. Theoretical Considerations
Stephen R. Kane, Kailash C. Sahu
The observed spectra of the microlensed sources towards the Galactic bulge may be used as a tool for studying the kinematics and extinction effects in the Galactic bulge. In this p…
H-alpha Equivalent Width Variations across the Face of a Microlensed K Giant in the Galactic Bulge
M. Albrow, J. An, J. -P. Beaulieu +14
We present VLT FORS1 spectroscopy that temporally resolves the second caustic crossing of the Bulge K giant source of microlensing event EROS 2000-BLG-5, the first time this has be…
Limits on the Abundance of Galactic Planets From Five Years of Planet Observations
M. D. Albrow, J. An, J. -P. Beaulieu +21
We search for signatures of planets in 43 intensively monitored microlensing events that were observed between 1995 and 1999. Planets would be expected to cause a short duration (~…
Microlensing Constraints on the Frequency of Jupiter Mass Planets
B. Scott Gaudi, M. D. Albrow, Jin H. An +17
Microlensing is the only technique likely, within the next 5 years, to constrain the frequency of Jupiter-analogs. The PLANET collaboration has monitored nearly 100 microlensing ev…
PLANET observations of microlensing event OGLE-1999-BUL-23: limb darkening measurement of the source star
M. D. Albrow, J. An, J. -P. Beaulieu +17
We present PLANET observations of OGLE-1999-BUL-23, a binary-lens microlensing event towards the Galactic bulge. PLANET observations in the I and V bands cover the event from just…
