Carbon-enhanced Metal-poor Stars in SDSS/SEGUE. I. Carbon Abundance Estimation and Frequency of CEMP Stars

Young Sun Lee, Timothy C. Beers, Thomas Masseron +8

We describe a method for the determination of stellar [C/Fe] abundance ratios using low-resolution (R = 2000) stellar spectra from the SDSS and SEGUE. By means of a star-by-star co…

The Neutron Star Mass Distribution

Bulent Kiziltan, Athanasios Kottas, Maria De Yoreo +1

In recent years, the number of pulsars with secure mass measurements has increased to a level that allows us to probe the underlying neutron star (NS) mass distribution in detail.…

The Role of Stellar Feedback in the Dynamics of HII Regions

Laura A. Lopez, Mark R. Krumholz, Alberto D. Bolatto +3

Stellar feedback is often cited as the biggest uncertainty in galaxy formation models today. This uncertainty stems from a dearth of observational constraints as well as the great…

Is there a metallicity ceiling to form carbon stars? - A novel technique reveals a scarcity of C stars in the inner M31 disk

M. L. Boyer, L. Girardi, P. Marigo +10

We use medium-band near-infrared (NIR) Hubble Space Telescope WFC3 photometry with model NIR spectra of Asymptotic Giant Branch (AGB) stars to develop a new tool for efficiently di…

The 10830 He I Absorption Line Among Metal-Poor Subdwarfs

Graeme H. Smith, Andrea K. Dupree, Jay Strader

Spectra of the He I 10830 line have been obtained for 23 metal-poor stars, the majority of which are dwarfs ranging in metallicity from [Fe/H] = -2.1 to -0.8. The data were acquire…
