DESCRIPTION:M dwarfs provide one of the most promising routes to measure t
 he atmospheres of rocky exoplanets. However\, exoplanets in orbit around M
  dwarfs must contend with high and prolonged XUV irradiation that can comp
 letely remove their atmospheres\, raising the question of which\, if any\,
  rocky exoplanets around M dwarfs retain an atmosphere? One way to address
  this question is to determine whether M dwarf rocky exoplanets follow a 
 “Cosmic Shoreline”\, an extrapolation of the irradiation–escape velo
 city relation observed in the Solar System that separates objects with atm
 ospheres from those without. I will present results from JWST GO 1981 that
  is probing the existence of an M dwarf Cosmic Shoreline through transmiss
 ion spectroscopy of five rocky exoplanets around M dwarfs.
