sunstardb - The Solar Stellar Database

The sunstardb database service was decommissioned on July 15, 2021.  All code and data are available from the GitHub repository.  Please contact the project lead ricky dot egeland at gmail dot com for any questions.

Sun / stars


sunstardb is a publicly accessible database of observations relevant to the study of stellar magnetism. These observations form the basis of the field known as the "solar-stellar connection," which seeks to understand the mechanisms for the production of magnetic field in stars and their dependence on fundamental properties such as mass, luminosity, etc., as well as to understand the place of the Sun's magnetism in this context. sunstardb aggregates and organizes results published in the literature into one place in order to accelerate research efforts in the solar-stellar connection.

sunstardb consists of the following components:

  • postgreSQL database
  • python APIs for interactive access
  • TODO: a web front-end for basic reporting of database contents

An article on the project has been accepted for publication in The Astrophysical Journal Supplement Series.


The current release of sunstardb is v0.5.0-beta, which was released on Sep 1, 2017. Instructions for accessing the database and all source code can be found in the code repository on GitHub. Future releases are planned for a quarterly cadence, and will be announced on this page and the mailing list.
