XUE 10. The CO2-rich terrestrial planet-forming region of an externally irradiated Herbig disk
Jenny Frediani, Arjan Bik, María Claudia Ramírez-Tannus +18
We investigate the James Webb Space Telescope (JWST) MIRI MRS gas molecular content of an externally irradiated Herbig disk, the F-type XUE 10 source, in the context of the eXtreme…
MINDS: Detection of an inner gas disk caused by evaporating bodies around HD 172555
M. Samland, T. Henning, A. Caratti o Garatti +23
Mechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planet…
MINDS: The very low-mass star and brown dwarf sample. Detections and trends in the inner disk gas
A. M. Arabhavi, I. Kamp, Th. Henning +22
Planet-forming disks around brown dwarfs and very low-mass stars (VLMS) are on average less massive and are expected to undergo faster radial solid transport than their higher mass…
