Roland

Introduction

roland is a generic stellar spectral synthesis package that can be run from python.

Description

To run roland you need 1) a model atmosphere, 2) a linelist (or multiple), and 3) the set of stellar parameters and elemental abundances that you want to run.

  1. Model Atmospheres

    MOOG can read Kurucz/ATLAS or MARCS model atmospheres. See pages 12-17 in the MOOG manual for the format and examples.

  2. Linelists

    MOOG requires a specific linelist format. See pages 20-21 in the MOOG manual for the format.

  3. Stellar parameters and elemental abundances.

    The main stellar parameters are Teff, logg, [M/H], and [alpha/M]. These are the first four parameters in the main synthesis.synthesize() function. The individual elements abundances are given in the elems parameters as a list of [element name, abundance] pairs, where abundance in the in [X/M] format relative to the overall metallicity.
