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 (~…
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…
Discovery of the optical counterpart and early optical observations of GRB990712
Kailash C. Sahu
We present the discovery observations of the optical counterpart of the gamma-ray burster GRB990712 taken 4.16 hours after the outburst and discuss its light curve observed in the…
