Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way

L. M. Howes, A. R. Casey, M. Asplund +22

The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…

Red noise versus planetary interpretations in the microlensing event OGLE-2013-BLG-446

E. Bachelet, D. M. Bramich, C. Han +98

For all exoplanet candidates, the reliability of a claimed detection needs to be assessed through a careful study of systematic errors in the data to minimize the false positives r…

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…
