Detection of Extrasolar Planets by Gravitational Microlensing (2009)
Gravitational microlensing provides a unique window on the properties and prevalence of extrasolar planetary systems because of its ability to find low-mass planets at separations of a few AU. The...
Ground-based Microlensing Surveys (2007)
Gould, Andrew, Gaudi, B. Scott, Bennett, David P.
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 formation ``beyond the...
Discovery of a Very Bright, Nearby Gravitational Microlensing Event (2007)
Gaudi, B. Scott, Patterson, Joseph, Spiegel, David S., Krajci, Thomas, Koff, R., Pojmanski, G., ...
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) brightened...
Characterization of Gravitational Microlensing Planetary Host Stars (2006)
Bennett, David P., Anderson, Jay, Gaudi, B. Scott
The gravitational microlensing light curves that reveal the presence of extrasolar planets generally yield the planet-star mass ratio and separation in units of the Einstein ring radius. The...
Identification of the OGLE-2003-BLG-235/MOA-2003-BLG-53 Planetary Host Star (2006)
Bennett, David P., Anderson, Jay, Bond, Ian A., Udalski, Andrzej, Gould, Andrew
We present the results of HST observations of the host star for the first definitive extrasolar planet detected by microlensing. The light curve model for this event predicts that the lens star...
Systematic Analysis of 22 Microlensing Parallax Candidates (2005)
Poindexter, Shawn, Afonso, Cristina, Bennett, David P., Glicenstein, Jean-Francois, Gould, Andrew, Szymanski, Michal K., ...
We attempt to identify all microlensing parallax events for which the parallax fit improves \Delta\chi^2 > 100 relative to a standard microlensing model. We outline a procedure to identify three...
Large Magellanic Cloud Microlensing Optical Depth with Imperfect Event Selection (2005)
I present a new analysis of the MACHO Project 5.7 year Large Magellanic Cloud (LMC) microlensing data set that incorporates the effects of contamination of the microlensing event sample by variable...
Photometric Confirmation of MACHO Large Magellanic Cloud Microlensing Events (2005)
Bennett, David P., Becker, Andrew C., Tomaney, Austin
We present previously unpublished photometry of three Large Magellanic Cloud (LMC) microlensing events and show that the new photometry confirms the microlensing interpretation of these events. These...
Systematic analysis of 22 microlensing parallax candidates (2005)
Poindexter, Shawn, Afonso, Cristina, Bennett, David P., Glicenstein, Jean-Francois, Gould, Andrew, Szymanski, Michal K., ...
We attempt to identify all microlensing parallax events for which the parallax fit improves Deltachi2>100 relative to a standard microlensing model. We outline a procedure to identify three types of...
The Mass of the MACHO-LMC-5 Lens Star (2004)
Gould, Andrew, Bennett, David P., Alves, David R.
We combine the available astrometric and photometric data for the 1993 microlensing event MACHO-LMC-5 to measure the mass of the lens, M=0.097 +/- 0.016 Msun. This is the most precise direct mass...
I compare an aggressive ground-based gravitational microlensing survey for terrestrial planets to a space-based survey. The Ground-based survey assumes a global network of very wide field-of-view ~2m...
Simulation of a Space-Based Microlensing Survey for Terrestrial Extra-Solar Planets (2000)
Bennett, David P., Rhie, Sun Hong
We show that a space-based gravitational microlensing survey for terrestrial extra-solar planets is feasible in the near future, and could provide a nearly complete picture of the properties of...
Bennett, David P., Rhie, Sun Hong
We present a conceptual design for a space based Galactic Exoplanet Survey Telescope (GEST) which will use the gravitational microlensing technique to detect extra solar planets with masses as low as...
Line Caustic Microlensing and Limb Darkening (1999)
Rhie, Sun Hong, Bennett, David P.
In a line caustic crossing microlensing event, the caustic line moving across the surface of the source star provides a direct method to measure the integrated luminosity profile of the star....
Red Clump Stars as a Tracer of Microlensing Optical Depth (1997)
Zaritsky and Lin have recently suggested that the color magnitude diagram of the Large Magellanic Cloud (LMC) contains evidence of foreground red clump stars. They interpret this as evidence of tidal...
Detecting Earth-Mass Planets with Gravitational Microlensing (1996)
Bennett, David P., Rhie, Sun Hong
We show that Earth mass planets orbiting stars in the Galactic disk and bulge can be detected by monitoring microlensed stars in the Galactic bulge. The star and its planet act as a binary lens which...
A Test of Gamma Ray Burst Recurrence in the BATSE 3B Data Set (1995)
Bennett, David P., Rhie, Sun Hong
We analyse the BATSE 3B catalog using the pair-matching statistic. This statistic counts only the burst pairs which may have originated from the same source, so it is less likely to yield false...
Is There Evidence for Repeating Gamma Ray Bursters in the BATSE Data? (1994)
Bennett, David P., Rhie, Sun Hong
The possibility that classical gamma ray bursts (GRB) occasionally repeat from the same locations on the sky provides a critical test of GRB models. There is currently some controversy about whether...
