Description
Young transiting exoplanets (<100 Myr) provide crucial insight into atmospheric evolution via photoevaporation. However, transmission spectroscopy measurements to determine atmospheric composition and mass loss are challenging due to the activity and prominent stellar surface inhomogeneities present on young stars. We observed a full transit of V1298 Tau c, a 23 Myr, 5.59
