HH 48 NE Protoplanetary Disk Ices at High Disk Altitudes
“To explain the presence of ices at high disk altitudes, we propose two possible scenarios: a disk wind that entrains sufficient amounts of dust, thus blocking part of the stellar UV radiation, or vertical mixing that cycles enough ices into the upper disk layers to balance ice photodesorption.” HH 48 NE is a protostar located…
