Exoplanet and Astrobiology

• Just started
• Help wanted: I am not very familiar with this topic, but it clearly has become one of the most important field in astronomy.

Transient Detection

• exoplanet - Fast & scalable MCMC for all your exoplanet needs
  • exoplanet is a toolkit for probabilistic modeling of transit and/or radial velocity observations of exoplanets and other astronomical time series using PyMC3.
  • By Dan Foreman-Mackey.
• pysyzygy - A fast and general planet transit (syzygy) code written in C and in Python
• tls - An optimized transit-fitting algorithm to search for periodic transits of small planets
  • By Michael Hippke. Based on this paper
  • TLS searches for transit-like features with stellar limb-darkening and including the effects of planetary ingress and egress
• planetplanet - A general photodynamical code for exoplanet light curves
  • By Rodrigo Luger. A general photodynamical code for modeling exoplanet transits, secondary eclipses, phase curves, and exomoons, as well as eclipsing binaries, circumbinary planets, and more
• PyLDTk - Python Limb Darkening Toolkit
  • a Python toolkit for calculating stellar limb darkening profiles and model-specific coefficients for arbitrary passbands using the stellar spectrum model library by Husser et al (2013)
• VESPA - Validation of Exoplanet Signals using a Probabilistic Algorithm
  • By Timothy Morton. It calculats false positive probabilities for transit signals
• juliet - a versatile modelling tool for transiting and non-transiting exoplanetary systems
  • By Néstor Espinoza. Based on the paper Espinoza et al. 2018
• exonailer - Tools for fitting transiting exoplanet lightcurves and radial velocities
  • By Néstor Espinoza. The EXOplanet traNsits and rAdIal veLocity fittER (EXO-NAILER), is an easy-to-use code that allows you to efficiently fit exoplanet transit lightcurves, radial velocities (RVs) or both.
• batman - Bad-Ass Transit Model cAlculatioN
  • batman, a Python package for fast calculation of exoplanet transit light curves.
  • Based on the paper by Laura Kreidberg

Direct Imaging

• PynPoint - Pipeline for processing and analysis of high-contrast imaging data
  • PynPoint is a generic, end-to-end pipeline for the data reduction and analysis of high-contrast imaging data of planetary and substellar companions, as well as circumstellar disks in scattered light.
  • Online document can be found here
• orbitize - Orbit-fitting for directly imaged objects

Radial Velocity

• wobble - precise data-driven RV fitting, now with tellurics
  • By Megan Bedell wobble is an open-source python package for analyzing time-series spectra. It was designed with stabilized extreme precision radial velocity (EPRV) spectrographs in mind, but is highly flexible and extensible to a variety of applications.
• radvel - General Toolkit for Modeling Radial Velocity Data
  • Based on the publication by Fulton et al. 2018

Planet Atmosphere

• PandExo - A Community Tool for Transiting Exoplanet Science with the JWST & HST
  • Tools to help the community with planning exoplanet observations
  • By Natasha Batalha
