Enceladus Offers Clues In The Search For Extraterrestrial Life
[Free University Berlin] With a global ocean of liquid water below a thick crust of ice, Saturn’s moon Enceladus is one of the most promising places to search for life […]

JWST Detection Of Methane Emission From A Young Brown Dwarf
[astro-ph.EP] In recent studies, we have used low-resolution spectroscopy (R~100) with the James Webb Space Telescope (JWST) to uncover low-mass brown dwarfs (2-10 MJup) in the young cluster IC 348 […]

Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
[astro-ph.EP] 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 vertical mixing, photochemistry, and […]

Laboratory Evidence that Methanol-Rich Ice Mantles Lower Methyl Formate Binding Energies
[astro-ph.IM] Complex organic molecules are widely detected in star-forming regions and are important precursors to prebiotic species. Because these molecules are thought to form primarily within icy grain mantles, their […]

Thermal Evolution of Lava Planets Across System Ages: Predictions for Hell of a Survey
[astro-ph.EP] Ultra-short-period (USP) rocky exoplanets can have dayside temperatures high enough to maintain permanent magma oceans, sitting at the intersection of interior geophysics and atmospheric chemistry. Coupled feedbacks between the […]

Thioacetaldehyde (CH3CHS) On Interstellar Ices: A Key Molecule To Unravel Two Chemical Dichotomies In The ISM
[astro-ph.GA] Thioacetaldehyde (CH3CHS), recently detected in TMC-1, has an abundance approximately 36 times lower than its oxygen analog, acetaldehyde (CH3CHO). This makes the CH3CHS/CH3CHO pair the one with the largest […]

Interstellar Disparity: N- vs O-bearing Molecules: A Multidisciplinary Perspective across Interstellar Environments
[astro-ph.GA] Observations of O- and N-bearing molecules reveal systematic chemical differentiation across a wide range of interstellar environments.

A Binary Flux Calibrator Reveals the Scientific Potential of Short-integration JWST MIRI Imaging to Directly Detect sub-Jupiter Exoplanets
[astro-ph.EP] We report the direct imaging detection of a stellar companion to HD 101452 (HIP 56925; Gaia DR3 5384905720847544192), an A star historically used as an infrared flux calibrator.
