Casual picture of me in a balloon chair C. E. Brasseur

I am currently a PhD student studying with Dr. Moira Jardine at the University of St Andrews, where my research focuses on magnetic fields on cool stars. I also have an interest in multi-wavelength studies of stellar flares. In addition to stellar astronomy I am a dedicated astronomical software developer, and am involved in the Astropy Project where I am a maintainer for the Astroquery package.

Research

Best flare Another nice flare Neighboring flares

I work with Dr. Rachel Osten, studying stellar flares in the optical and near-ultraviolet, making use of the GALEX and Kepler space telescope surveys. We detected a collection of short-duration ultra-violet flares in the GALEX data, my favorites of which are pictured above. This work is published in Brasseur et al. 2019 and a forthecoming paper will discuss associated Kepler observations.

Astrocut

Astrocut contains cutout tools for astronomical data. It offers efficent cutouts of Transiting Exoplanet Survey Satellite full-frame image sets as well as more generic "fits-cut" tools. Astrocut is the software that backs the TESScut and zCut cutout services. I was the original developer and maintainer for this package.

Astroquery

Astroquery is a set of tools for querying astronomical web forms and databases. It provides streamlined Python access to a plethora of astronomical archives and datasets. I am a package maintainer.

Astronify

Astronify contains tools for sonifying astronomical data, particulary timeseries data such as light curves. I am the lead developer and maintainer of this project.
