Clues to the Metallicity Distribution in the Galactic Bulge: Abundances in OGLE-2007_BLG-349S
Judith G. Cohen, Wenjin Huang, A. Udalski +2
We present an abundance analysis based on high dispersion and high signal-to-noise ratio Keck spectra of a very highly microlensed Galactic bulge dwarf, OGLE-2007-BLG-349S, with Te…

Hexadecapole Approximation in Planetary Microlensing
Andrew Gould
The frequency of microlensing planet detections, particularly in difficult-to-model high-magnification events, is increasing. Their analysis can require tens of thousands of proces…
