JWST’s Sharper View Of EX Lup: Cold Water From Ice Sublimation During Accretion Outbursts
The unstable accretion phases during pre-main-sequence evolution of T Tauri stars produce variable irradiation and heating of planet-forming regions.

MINDS: The Very Low-mass Star And Brown Dwarf Sample — Hidden Water In Carbon-dominated Protoplanetary Disks
Infrared observations of the inner disks around very low-mass stars (VLMS, <0.3M⊙) have revealed a carbon-rich gas composition in the terrestrial planet-forming regions. Contrary to the typically water-rich T Tauri […]
