Astronomers led by a team at Université de Montréal has made important progress in understanding the intriguing TRAPPIST-1 exoplanetary system, which was first discovered in 2016 amid speculation it could someday provide a place for humans to live.
Not only does the new research shed light on the nature of TRAPPIST-1 b, the exoplanet orbiting closest to the system's star, it has also shown the importance of parent stars when studying exoplanets.
Published in Astrophysical Journal Letters, the findings by astronomers at UdeM's Trottier Institute for Research on Exoplanets (iREx) and colleagues in Canada, the U.K. and U.S. shed light on the complex interplay between stellar activity and exoplanet characteristics.
