On the stability of planetary orbits in binary star systems I. The S-type orbits

This repository contains the results for a test particle (massEqZero directory), a Jupiter-mass (massEqMj directory), and 30 Jupiter mass planets (massEq30Mj directory).

The data are published for any binary mass ratio and eccentricity, applying a common naming scheme. For example, the csv file:

massEqZero/mu_0.5/e_0.5/0/index_a.csv

contains the data for a test particle in a binary with a mass ratio $\mu = 0.5$ and an eccentricity $e = 0.5$ with binary initially at apoapse, at the first initial longitude (see Table 1 in the paper). Note that the data are defined by the path not by the file name, that is the same for any configuration.

In the csv file the stability flag can have one of the following values:

• ST: stable orbit
• CA: the planet collides with the primary star after a given (t_stop) time
• CB: the planet collides with the secondary star
• EJ: ejection

Note: The repository does not contains the raw file with orbits. Please, ask to the authors if you are also interested to these data.

How to use the archive

First clone the repository, then use python (or any language you prefer) to read and process the csv files.
