Direct imaging characterization of cool gaseous planets

Michiel Min, Jo Barstow, Laura C. Mayorga +19

Cool gas giant exoplanets, particularly those with properties similar to those of Jupiter and Saturn, remain poorly characterized due to current observational limitations. This whi…

Astroclimes -- measuring the abundance of CO and CH in the Earth's atmosphere using astronomical observations

Marcelo Aron Fetzner Keniger, David Armstrong, Matteo Brogi +2

Monitoring the abundance of greenhouse gases (GHGs) such as carbon dioxide (CO) and methane (CH) is necessary to quantify their impact on global warming and climate change.…

The Roasting Marshmallows Program with IGRINS on Gemini South III: Seeing deeper into the metal depleted atmosphere of a gas-giant on the cusp of the hot to ultra-hot Jupiter transition

Vatsal Panwar, Matteo Brogi, Krishna Kanumalla +17

Ultra-hot Jupiters are a class of gas-giant exoplanets that show a peculiar combination of thermochemical properties in the form of molecular dissociation, atomic ionization, and i…

Tracing the formation and migration history: molecular signatures in the atmosphere of misaligned hot Jupiter WASP-94Ab using JWST NIRSpec/G395H

Eva-Maria Ahrer, Siddharth Gandhi, Lili Alderson +12

The discovery of hot Jupiters that orbit very close to their host stars has long challenged traditional models of planetary formation and migration. Characterising their atmospheri…

Detectability of oxygen fugacity regimes in the magma ocean world 55 Cancri e at high spectral resolution

Spandan Dash, Matteo Brogi, Fabian Lukas Seidler +5

Ultra-short Period exoplanets (USPs) like 55 Cnc e, hosting dayside magma oceans, present unique opportunities to study surface-atmosphere interactions. The composition of a vapori…

The mystery of water in the atmosphere of Boötis b continues: insights from revisiting archival CRIRES observations

Vatsal Panwar, Matteo Brogi, Siddharth Gandhi +2

The chemical abundances of gas-giant exoplanet atmospheres hold clues to the formation and evolution pathways that sculpt the exoplanet population. Recent ground-based high-resolut…
