Detection of CO, CO, and HO in the atmosphere of the warm sub-Saturn HAT-P-12b
N. Crouzet, B. Edwards, T. Konings +29
The chemical composition of warm gas giant exoplanet atmospheres (with Teq < 1000 K) is not well known due to the lack of observational constraints. HAT-P-12 b is a warm, sub-Satur…
MINDS. Anatomy of a water-rich, inclined, brown dwarf disk: lack of abundant hydrocarbons
Giulia Perotti, Nicolás T. Kurtovic, Thomas Henning +23
2MASS J04381486+2611399 (or J0438) is one of the few young brown dwarfs (BD) with a highly inclined () disk. Here we report results from JWST-MIRI MRS, HST-ACS a…
SO2, silicate clouds, but no CH4 detected in a warm Neptune
Achrene Dyrek, Michiel Min, Leen Decin +44
WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…
Extended source fringe flats for the JWST MIRI Medium Resolution Spectrometer
N. Crouzet, M. Mueller, B. Sargent +17
The detectors of the JWST Mid-Infrared Instrument (MIRI) Medium Resolution Spectrometer (MRS) form low-finesse resonating cavities that cause periodic count rate modulations (fring…
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…
MINDS: The very low-mass star and brown dwarf sample -- Hidden water in carbon-dominated protoplanetary disks
Aditya M. Arabhavi, Inga Kamp, Ewine F. van Dishoeck +21
Infrared observations of the inner disks around very low-mass stars (VLMS, 0.3) have revealed a carbon-rich gas composition in the terrestrial planet-forming region…
