the Exoplanet Population Observation Simulator

EPOS is a software package to simulate observations of exoplanet populations. It provides an interface between planet formation simulations and exoplanet surveys such as Kepler, accounting for detection biases in transit and radial velocity surveys. _images/epos-arrows.png


Use EPOS to calculate:

  • Planet ocurrence rates (notebook)
  • Planet occurrence rate distributions (notebook)
  • Planetary system architectures (notebook)
  • Synthetic observations of planet formation models
  • Survey biases of transit surveys other than Kepler (notebook)
  • Planet populations in radial velocity surveys (notebook)
  • Binned planet occurrence rates


EPOS is written in Python 3 and hosted on github.

The quickest way to install epos is via pip:

pip install epospy
