The GALAH Survey: Scientific Motivation
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +44
The GALAH survey is a large high-resolution spectroscopic survey using the newly commissioned HERMES spectrograph on the Anglo-Australian Telescope. The HERMES spectrograph provide…
Uncertainties in The Interstellar Extinction Curve and the Cepheid Distance to M101
David M. Nataf
I revisit the Cepheid-distance determination to the nearby spiral galaxy M101 (Pinwheel Galaxy) of Shappee & Stanek (2011), in light of several recent investigations questioning th…
The X-Shaped Milky Way Bulge in OGLE-III Photometry and in N-Body Models
David M. Nataf, Andrzej Udalski, Jan Skowron +11
We model the split red clump of the Galactic bulge in OGLE-III photometry, and compare the results to predictions from two N-body models. Our analysis yields precise maps of the br…
Red Giant Branch Bump Star Counts in Data and Stellar Models
David M. Nataf
We compare model predictions to observations of star counts in the red giant branch bump (RGBB) relative to the number density of first-ascent red giant branch at the magnitude of…
The Gaia-ESO Survey: the most metal-poor stars in the Galactic bulge
L. Howes, M. Asplund, A. R. Casey +39
We present the first results of the EMBLA survey (Extremely Metal-poor BuLge stars with AAOmega), aimed at finding metal-poor stars in the Milky Way bulge, where the oldest stars s…
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…
