Reddening and Extinction Toward the Galactic Bulge from OGLE-III: The Inner Milky Way's Rv ~ 2.5 Extinction Curve
David M. Nataf, Andrew Gould, Pascal Fouqué +11
We combine VI photometry from OGLE-III with VVV and 2MASS measurements of E(J-K_{s}) to resolve the longstanding problem of the non-standard optical extinction toward the Galactic…
Constraining the structure and formation of the Galactic bulge from a field in its outskirts. FLAMES-GIRAFFE spectra of about 400 red giants around (l,b)=(0°,-10°)
Stefan Uttenthaler, Mathias Schultheis, David. M. Nataf +3
The presence of two stellar populations in the Milky Way bulge has been reported recently. We aim at studying the abundances and kinematics of stars in the outer bulge, thereby pro…
MOA-2010-BLG-477Lb: constraining the mass of a microlensing planet from microlensing parallax, orbital motion and detection of blended light
E. Bachelet, I. -G. Shin, C. Han +138
Microlensing detections of cool planets are important for the construction of an unbiased sample to estimate the frequency of planets beyond the snow line, which is where giant pla…
Detached Red Giant Eclipsing Binary Twins: Rosetta Stones to the Galactic Bulge
David M. Nataf, Andrew Gould, Marc H. Pinsonneault
We identify 34 highly-probable detached, red giant eclipsing binary pairs among 315 candidates in Devor's catalog of 10,000 OGLE-II eclipsing binaries. We estimate that there…
