Title: HD 185330 — chemically peculiar ³He star in the Kepler field
Keyword(s): stars: chemically peculiar, stars: atmospheres, stars: abundances
Pages: 287 -- 288

Abstract: We analyzed high-resolution spectra of the chemically peculiar ³He star HD 185330. We determined its atmospheric parameters (T_eff, log g, ξ) and constrained its rotation velocity and abundance pattern. In particular, we found a large (×100) phosphorus abundance excess and evidence of ³He and ⁴He abundance stratification in the atmosphere.
