The surface brightness of the Galaxy at the Solar Neighbourhood
A. -L. Melchior, F. Combes, A. Gould
We present a new determination of the surface brightness of our Galaxy at the Solar Neighbourhood as observed from outside the Galaxy. We rely on various existing optical and infra…
Origin of the Break and Mass-Dependence in the Wide-Binary Projected-Separation Distribution
Andrew Gould, Jason Eastman
The distribution of Galactic-disk wide binaries shows a clear break in slope at projected separations of about r_\perp ~ 2500 AU in two basically independent surveys by Chaname & G…
Limits on the Macho Content of the Galactic Halo from the EROS-2 Survey of the Magellanic Clouds
P. Tisserand, L. Le Guillou, C. Afonso +35
The EROS-2 project was designed to test the hypothesis that massive compact halo objects (the so-called ``machos'') could be a major component of the dark matter halo of the Milky…
Identification of the OGLE-2003-BLG-235/MOA-2003-BLG-53 Planetary Host Star
David P. Bennett, Jay Anderson, Ian A. Bond +2
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…
Removing the Microlensing Blending-Parallax Degeneracy Using Source Variability
R. J. Assef, A. Gould, the EROS-2 +2
Microlensing event MACHO 97-SMC-1 is one of the rare microlensing events for which the source is a variable star, simply because most variable stars are systematically eliminated f…
Protecting Life in the Milky Way: Metals Keep the GRBs Away
K. Z. Stanek, O. Y. Gnedin, J. F. Beacom +7
The host galaxies of the five local, z<0.25, long-duration gamma-ray bursts, each of which had a well-documented associated supernova, are all faint and metal-poor compared to the…
The OGLE-II event sc5_2859 : a Classical Nova outburst?
C. Afonso, J. F. Glicenstein, A. Gould +3
The OGLE-II event sc5_2859 was previously identified as the third longest microlensing event ever observed. Additional photometric observations from the EROS (Experience de Recherc…
Frequency of Hot Jupiters and Very Hot Jupiters from the OGLE-III Transit Surveys Toward the Galactic Bulge and Carina
Andrew Gould, Susan Dorsher, B. Scott Gaudi +1
We derive the frequencies of hot Jupiters (HJs) with 3--5 day periods and very hot Jupiters (VHJs) with 1-3 day periods by comparing the planets actually detected in the OGLE-III s…
Galactic Bulge Microlensing Optical Depth from EROS-2
C. Hamadache, L. Le Guillou, P. Tisserand +34
We present a new EROS-2 measurement of the microlensing optical depth toward the Galactic Bulge. Light curves of clump-giant stars distributed over of t…
