VizieR Online Data Catalog: Grid of NLTE EW and NLTE corrections BaII lines (Korotin+, 2015)
Abstract
The following stellar parameter ranges are covered by our grid, which focuses on more metal-rich stars (compared to the very metal-poor and extremely metal-poor stas) that are typically targeted in current and future surveys:
- effective temperature: 4000-6500K, step = 250K; - surface gravity: 0-5, step = 0.5 - microturbulent velocity: 0-3km/s, step = 1km/s; - metallicity: [Fe/H] = +0.5, 0.0, -0.5, -1.0, -1.5 and -2.0; - relative barium abundance: [Ba/Fe] = -0.40, -0.20, 0.00, +0.20, +0.40, +0.60. For the models with [Fe/H] below -1.00 we calculated NLTE equivalent widths with an increased atmosphere abundance of alpha-elements ([alpha/Fe]=+0.4), while for a metallicity of -0.5 both cases (solar alpha-element abundance and an increased one) were considered. The NLTE equivalent widths of the four barium lines were calculated: 4554, 5853, 6141, and 6496Å. Tables 4 and 5 contain the NLTE equivalent widths and NLTE corrections, respectively. For each barium line we selected six values of [Ba/Fe] (-0.4, -0.2, 0.0, +0.2, +0.4 and +0.6) for the NLTE EW grid, and three values of [Ba/Fe] (-0.2, 0.1, and +0.4) for the NLTE correction grid. For each of these values we list in the corresponding table the EWs or corrections calculated for the full set of effective temperature, surface gravity, microturbulent velocity, and metallicity.
