NASA Exoplanet Archive: Getting CUTE With New Data

The archive has added a new dataset by NASA’s Colorado Ultraviolet Transit Experiment (CUTE)
CubeSat. The mission is measuring near-ultraviolet transmission spectroscopy of a dozen Jupiter- and Neptune-sized planets and monitoring the stellar activity of the host stars.

The NASA Exoplanet Archive will host the spectroscopic time series for each transit observation. In this initial release, we are serving 20 transits across four planets: KELT-9 b, KELT-20 b, MASCARA-4 b, and WASP-189 b. Our Firefly-based interface provides a central location to browse, plot, and download the data, which include time series spectra and 2D FITS images.

To get started, click the Data pull-down menu in our site navigation and select CUTE Mission in the Other section, or go directly to https://exoplanetarchive.ipac.caltech.edu/cgi-bin/CUBESAT/nph-cubesat?cute.

Note: The Exoplanet Archive’s interface provides access to the time series spectroscopy used to measure the transmission spectra, which will eventually also be served through the archive’s Atmospheric Spectroscopy Table.

More information about CUTE mission data and the online service is provided on the User Guide tab within the interface.
