  • The SEGUE Stellar Parameter Pipeline. V. Estimation of Alpha-element Abundance Ratios from Low-resolution SDSS/SEGUE Stellar Spectra 
    Lee, Y. S; Beers, T. C; Prieto, C. A; Lai, D. K; Rockosi, C. M; Morrison, H. L; Johnson, J. A; An, D; Sivarani, T; Yanny, B (IOP Publishing, 2011-03)
    We present a method for the determination of [α/Fe] ratios from low-resolution (R = 2000) SDSS/SEGUE stellar spectra. By means of a star-by-star comparison with degraded spectra from the ELODIE spectral library and with a ...

P; Shelden, A; Simmons, A; Sivarani, T; van Eyken, J. C; Wan, X; Weaver, B. A; Zhao, Bo (IOP Publishing, 2013-01)
    We present an eccentric, short-period brown dwarf candidate orbiting the active, slightly evolved subgiant star TYC 2087-00255-1, which has effective temperature T eff = 5903 ± 42 K, surface gravity log (g) = 4.07 ± 0.16 ...
