Binary contamination in the SEGUE sample: Effects on SSPP determinations of stellar atmospheric parameters

Schlesinger, Katharine; Johnson, Jennifer A; Lee, Young Sun; Masseron, Thomas; Yanny, Brian; Rockosi, Constance; Gaudi, B S; Beers, Timothy C


We examine the effects that unresolved binaries have on the determination of various stellar atmospheric parameters for targets from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) using numerical modeling, a grid of synthetic spectra, and the SEGUE Stellar Parameter Pipeline (SSPP). The SEGUE survey, a component of the Sloan Digital Sky Survey-II (SDSS-II) project focusing on Galactic structure, provides medium resolution spectroscopy for over 200,000 stars of various...[Show more]
