trappist1.py

This module hosts TRAPPIST-1-specific routines.

planetplanet.photo.trappist1.Trappist1(sample=True, distance=12, seed=None, **kwargs)

Returns an instance of planetplanet.photo.System for the full TRAPPIST-1 system. Star and planet parameters are drawn from their respective prior distributions, which are based on the observed values from Gillon et al. (2017), Luger et al. (2017), and Burgasser & Mamajek (2017). Longitudes of ascending node are drawn from the \(\theta\) distribution derived in the paper.

Parameters:
  • sample (bool) – Draw a random sample from the full prior? If False,returns the mean values for all parameters. Default True
  • distance (float) – Distance to the system in parsecs. Default 12
  • seed (int) – Random number generator seed. Default None
  • kwargs – Any other kwargs to be passed to planetplanet.Star(), planetplanet.Planet(), and planetplanet.System().
