Enhancing the performance and capabilities of the MIRI instrument on JWST
S. Kendrew, M. Engesser, K. Rowlands +23
MIRI, the Mid-Infrared Instrument on the James Webb Space Telescope, is the only instrument sensitive to wavelengths longward of 5 um on the observatory. In this regime, MIRI bring…
ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution
Allison Youngblood, Kevin France, Brian Fleming +37
The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…
A Search for Wide-orbit Planets Around M-dwarfs using Deep MIRI 15-micron Images
Yihan Li, Yifan Zhou, Rachel Bowens-Rubin +7
Wide-orbit (10 AU) gas giant planets shape the architecture of planetary systems, yet their occurrence rate remains poorly constrained. JWST has obtained the deepest mid-infrare…
Hot Rocks Survey V: Secondary Eclipse Photometry of GJ 3473 b with JWST/MIRI
Måns Holmberg, Hannah Diamond-Lowe, João M. Mendonça +16
JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmo…
A break in planet occurrence near the pebble isolation mass should be observable by the Roman microlensing survey
Claudia Danti, Michiel Lambrechts, Hannah Diamond-Lowe
Microlensing detections are uniquely well-suited to probing the population of planets outside the water iceline, down to planetary masses comparable to the Earth. Here, we perform…
Atmospheric constraints on GJ 1214 b from CRIRES+ and prospects for characterisation with ANDES
A. Peláez-Torres, A. Sánchez-López, C. Jiang +5
In this study, we aim to constrain the atmospheric composition of GJ 1214 b using all available transits observed with the upgraded CRIRES+ spectrograph at the VLT by searching for…
