MINDS program
MIRI mid-INfrared Disk Survey (MINDS) is a James Webb Space Telescope (JWST) guaranteed time observation program comprising of several European institutions (PID: 1282, PI: Thomas Henning). This program conducts infrared spectroscopic observations of diverse protoplanetary disks using MIRI and NIRSpec instruments on JWST.

2D disc modelling of the JWST line spectrum of EX Lupi
Nov, 2023
We introduce a number of new theoretical approaches and improvements to the thermo-chemical disc modelling code ProDiMo to better predict and analyse the JWST line spectra of protoplanetary discs. We develop a new line escape probability method for disc geometries, a new scheme for dust settlin...
The distribution of volatile elements during rocky planet formation
Nov, 2023
Core segregation and atmosphere formation are two of the major processes that redistribute the volatile elements-hydrogen (H), carbon (C), nitrogen (N), and sulfur (S)-in and around rocky planets during their formation. The volatile elements by definition accumulate in gaseous reservoirs and fo...
SO$_2$, silicate clouds, but no CH$_4$ detected in a warm Neptune
Nov, 2023
WASP-107b is a warm ($\sim$740 K) transiting planet with a Neptune-like mass of $\sim$30.5 $M_{\oplus}$ and Jupiter-like radius of $\sim$0.94 $R_{\rm J}$, whose extended atmosphere is eroding. Previous observations showed evidence for water vapour and a thick high-altitude condensate layer in W...
15NH3 in the atmosphere of a cool brown dwarf
Nov, 2023
Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits as the governing physical and chemical processes in them are nearly identical. Understanding the formation of gas giant planets is challenging, often involving the endeavour to link atmosphe...
MINDS. Abundant water and varying C/O across the disk of Sz 98 as seen by JWST/MIRI
Oct, 2023
MIRI/MRS on board the JWST allows us to probe the inner regions of protoplanetary disks. Here we examine the disk around the classical T Tauri star Sz 98, which has an unusually large dust disk in the millimetre with a compact core. We focus on the H$_2$O emission through both its ro-vibrationa...
A roadmap to the efficient and robust characterization of temperate terrestrial planet atmospheres with JWST
Oct, 2023
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominent is the M8.5V star TRAPPIST-1 and its seven planets, which have been the favored targets of eight JWST Cycle 1 pro...
