Introduction¶

This python interface serves as a link between the raw XML of the: Open Exoplanet Catalogue. It allows:

Searching of planets (including alternate names)
Easy reference of planet parameters ie GJ1214b.ra, GJ1214b.T, GJ1214b.R
Calculation of values like the transit duration.
Define planet types and query planets to find out what they are
Easy rescale of units
Easily navigate hierarchy (ie from planet to star or star to planets)
Availability of system parameters in planets (ie ra, dec, d (distance))

If you use ExoData in a scientific publication, please include a reference to this paper 2015arXiv151002738V.

Installation¶

Install ExoData by running:

pip install exodata

Or download the repo and run

python setup.py install

Getting Started¶

These docs are a work in progress and quite incomplete. The best place to start at present is the readme on the project github page. If you want more information the paper gives some more information and examples.

Modules¶

ExoData is split into a series of modules dealing with the exoplanet database, equations, plots and units.

Module	Description
Assumptions	Holds classification assumptions such as at what mass or radius a planet is defined as a super-Earth.
Astroclasses	Classes for the System, Binary, Star and Planet object types.
Astroquantities	Expands the Product Quantities Python package with astronomical units like Solar Radius and compound units such as \(g/cm^3\).
Database	Holds the database class and the various search methods.
Equations	Implementation of exoplanet related equations including orbital equations, planet and star characterisations and estimations.
Example	Generate example systems for testing code.
Flags	Each object has a flag object attached which lets you know which assumptions have been made such as “calculated temperature”.
Plots	Plot functions for common plot types that can be used to to easily display data from the catalogue.
