JWST’s Sharper View of EX Lup: Cold Water from Ice Sublimation during Accretion Outbursts

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. A strong accretion outburst was observed with Spitzer-InfraRed Spectrograph in 2008 in EX Lup, the prototype of EXor variables, and found to increase...
