Two articles, one to be published in “The Astronomical Journal” and one to be published in the journal “Astronomy and Astrophysics”, describe the study of the exoplanet K2-141b, a super-Earth very close to its star, so much that its year lasts only 6.7 hours. A team of researchers led by Luca Malavolta of the University of Padua and the Italian National Institute of Astrophysics used the National Galileo Telescope and its HARPS-N spectrograph to study it.
