Creating

The primary goal of exoatlas is to create populations of exoplanets which which we can interact in fairly standardized way. Here we summarize a few different pre-defined Population objects we can create.

Documentation to add:

  • Add some more details for populations.
  • Explain how to create your own default population.
  • Talk about filtering false positives in the TOI population.
In [1]:

import exoatlas as ea

Throughout this page we’ll use handy physical_summary() wrapper as a way to visualize some of the basic properties of a particular population. For more on useful plots and plotting tools, see Visualizing.

Solar System

The eight planets in our own Solar System are an extremely useful comparison sample.

Confirmed Planets

The NASA Exoplanet Archive maintains a list of confirmed transiting exoplanets. These are systems that have been characterized in sufficient detail that they are unlikely to be false positives.

This archive contains planets discovered through a variety of methods. We can access all exoplanets in the archive, regardless of discovery method, with:
