In this section, you will soon find short explanatory videos to better understand high-contrast imaging data and the ressources offered in the Exoplanet Imaging Data Challenge.

HR 8799 system orbit video

The young star HR 8799 hosts four giant gaseous planets (Marois et al., 2010). The following video shows 10 different epochs of post-processed high-contrast images of the HR 8799 system observed in the near-infrared over a period of 12 years, from 2009 to 2021. Data are taken using the NIRC2 instrument installed at the Keck Telescope (Mauna Kea observatory, Hawaii, USA).
