A research team led by scientists from IRAP (CNRS/CNES/Université Toulouse III—Paul Sabatier) and IPAG (CNRS/UGA) has for the first time measured the internal density of a very young exoplanet orbiting a newly formed, extremely active star. Despite the 'noise' generated by the star's activity, they successfully achieved this using the Canada-France-Hawaii Telescope (CFHT)'s planet hunting instrument SPIRou. The findings are published in MNRAS on 2 February 2021.
