Model Photospheres for Late‐Type Stars from the Inversion of High‐Resolution Spectroscopic Observations: Groombridge 1830 and ε Eridani
An inversion technique to recover LTE one-dimensional model photospheres for late-type stars, which was previously applied to the Sun (Allende Prieto et al. 1998), is now employed to reconstruct, semi-empirically, the photospheres of cooler dwarfs: the metal-poor Gmb1830 and the active star of solar-metallicity Eps Eri. The model atmospheres we …
