Finding Planets Around White Dwarf Remnants of Massive Stars
Andrew Gould, Mukremin Kilic
Planet frequency shows a strong positive correlation with host mass from the hydrogen-burning limit to M ~ 2Msun. No search has yet been conducted for planets of higher-mass hosts…
Investigation of the Contamination of the Gould (2003) Halo Sample
Andrew Gould
A recent astroph posting argued that the Gould (2003a) halo sample is substantially contaminated with thick-disk stars, which would then ``wash out'' any signature of granularity i…
Microlens Parallax Measurements with a Warm Spitzer
Andrew Gould
Because Spitzer is an Earth-trailing orbit, losing about 0.1 AU/yr, it is excellently located to perform microlens parallax observations toward the Magellanic Clouds (LMC/SMC) and…
Ground-based Microlensing Surveys
Andrew Gould, B. Scott Gaudi, David P. Bennett
Microlensing is a proven extrasolar planet search method that has already yielded the detection of four exoplanets. These detections have changed our understanding of planet format…
Discovery of a Very Bright, Nearby Gravitational Microlensing Event
B. Scott Gaudi, Joseph Patterson, David S. Spiegel +18
We report the serendipitous detection of a very bright, very nearby microlensing event. In late October 2006, an otherwise unremarkable A0 star at a distance ~1 kpc (GSC 3656-1328)…
