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 […]

Abundant Water From Primordial Supernovae At Cosmic Dawn

Primordial (or population III) supernovae were the first nucleosynthetic engines in the Universe, and they forged the heavy elements required for the later formation of planets and life. Water, in […]
