Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
Olivia Venot, Yamila Miguel, Robin Baeyens +30
Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…
Cosmic ray ionisation of a post-impact early Earth atmosphere: Solar cosmic ray ionisation must be considered in origin-of-life scenarios
S. R. Raeside, D. Rodgers-Lee, P. B. Rimmer
Cosmic rays (CR), both solar and Galactic, have an ionising effect on the Earth's atmosphere and are thought to be important for prebiotic molecule production. In particular, the $…
Abundant hydrocarbons in the disk around a very-low-mass star
A. M. Arabhavi, I. Kamp, Th. Henning +40
Very low-mass stars (those <0.3 solar masses) host orbiting terrestrial planets more frequently than other types of stars, but the compositions of those planets are largely unknown…
MINDS. The DR Tau disk I: combining JWST-MIRI data with high-resolution CO spectra to characterise the hot gas
Milou Temmink, Ewine F. van Dishoeck, Sierra L. Grant +29
The MRS mode of the JWST-MIRI instrument has been shown to be a powerful tool to characterise the molecular gas emission of the inner region of planet-forming disks. Here, we analy…
MINDS: The JWST MIRI Mid-INfrared Disk Survey
Thomas Henning, Inga Kamp, Matthias Samland +39
The study of protoplanetary disks has become increasingly important with the Kepler satellite finding that exoplanets are ubiquitous around stars in our galaxy and the discovery of…
MINDS. JWST-MIRI Reveals a Dynamic Gas-Rich Inner Disk Inside the Cavity of SY Cha
Kamber R. Schwarz, Thomas Henning, Valentin Christiaens +24
SY Cha is a T Tauri star surrounded by a protoplanetary disk with a large cavity seen in the millimeter continuum but has the spectral energy distribution (SED) of a full disk. Her…
The Chemical Inventory of the Inner Regions of Planet-forming Disks -- The JWST/MINDS Program
Inga Kamp, Thomas Henning, Aditya M. Arabhavi +40
The understanding of planet formation has changed recently, embracing the new idea of pebble accretion. This means that the influx of pebbles from the outer regions of planet-formi…
Water in the terrestrial planet-forming zone of the PDS 70 disk
G. Perotti, V. Christiaens, Th. Henning +42
Terrestrial and sub-Neptune planets are expected to form in the inner (AU) regions of protoplanetary disks. Water plays a key role in their formation, although it is yet uncl…
MINDS. Abundant water and varying C/O across the disk of Sz 98 as seen by JWST/MIRI
Danny Gasman, Ewine F. van Dishoeck, Sierra L. Grant +41
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 la…
A rich hydrocarbon chemistry and high C to O ratio in the inner disk around a very low-mass star
B. Tabone, G. Bettoni, E. F. van Dishoeck +43
Carbon is an essential element for life but how much can be delivered to young planets is still an open question. The chemical characterization of planet-forming disks is a crucial…
The energetic particle environment of a GJ 436 b-like planet
D. Rodgers-Lee, P. B. Rimmer, A. A. Vidotto +8
A key first step to constrain the impact of energetic particles in exoplanet atmospheres is to detect the chemical signature of ionisation due to stellar energetic particles and Ga…
Stellar versus Galactic: The intensity of energetic particles at the evolving Earth and young exoplanets
D. Rodgers-Lee, A. A. Vidotto, A. M. Taylor +2
Energetic particles may have been important for the origin of life on Earth by driving the formation of prebiotic molecules. We calculate the intensity of energetic particles, in t…
