Binary Star PDS 144B in Scorpius has a Proplyd – Ionized Protoplanetary Disk
PDS 144B is part of a binary star system known as PDS 144, which is notable for being the first confirmed Herbig Ae/Be binary system (2012) where both stars drive jets. Herbig Ae/Be stars are a class of pre-main-sequence stars that are more massive than T Tauri stars and are characterized by their emission lines…

Abundance of Water in the Form of Icy Crystals in the Frosty Leo Protoplanetary Nebula
The Frosty Leo Nebula, also known as IRAS 09371+1212, is a protoplanetary nebula located approximately 3,000 light-years from Earth in the constellation Leo. Despite their name, protoplanetary nebulae are not related to planets but are formed from material ejected by their aging central stars. Characteristics Observation Significance Protoplanetary nebulae like Frosty Leo are precursors to…

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…
