MODEL FOR ROTATION OF STARS (MORS)

MORS is a Python package for modelling the rotational spin-down and high-energy (X-ray, EUV, Ly-α) emission evolution of low-mass stars. It implements the model of Johnstone, Bartel & Güdel (2021) and is the stellar evolution model integrated into the PROTEUS framework.

Quickstart

import mors

star = mors.Star(Mstar=1.0, Prot=2.7)  # 1 Msun, initial rotation period at 1 Myr
print(star.Lx(150.0))                  # X-ray luminosity at 150 Myr [erg s-1]
