context_page_description: K2-32 is a G9-type main sequence star slightly smaller and less massive than the sun. Four confirmed transiting exoplanets are known to orbit this star. A study of atmospheric escape from the planet K2-32b caused by high-energy stellar irradiation indicates that the star has always been a very slow rotator.
context_section_description: The star K2-32 was initially found to have three transiting planet candidates by Andrew Vanderburg and collaborators in 2016. The innermost planet candidate, at that time, K2-32b was confirmed using radial velocity measurements made with the Keck telescope. Confirmation of planets c and d was made by Sinukoff et al. using adaptive optics imaging and computer analysis to eliminate possible false positives.
  The Earth-sized planet K2-32e was discovered and validated by René Heller and team in 2019.
