PySME -- Spectroscopy Made Easier

Ansgar Wehrhahn, Nikolai Piskunov, Tanja Ryabchikova

The characterization of exoplanet requires reliable determination of the fundamental parameters of their host stars. Spectral fitting plays an important role in this process. For t…

Non-LTE abundance corrections for late-type stars from 2000Å to 3μm: I. Na, Mg, and Al

K. Lind, T. Nordlander, A. Wehrhahn +6

It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Accurate abundance determination requires taking those effects into account, but the…
