A Tale of Two Sightlines: Comparison of Hydrocarbon Dust Absorption Bands toward Cygnus OB2-12 and the Galactic Center

Yvonne J. Pendleton, T. R. Geballe, Laurie E. U. Chu +14

Infrared spectra of hydrocarbon dust absorption bands toward the bright hypergiant Cygnus OB2-12 are compared to published spectra of the Quintuplet Cluster, a sightline to the Gal…

SO2, silicate clouds, but no CH4 detected in a warm Neptune

Achrene Dyrek, Michiel Min, Leen Decin +44

WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…

MINDS: Detection of an inner gas disk caused by evaporating bodies around HD 172555

M. Samland, T. Henning, A. Caratti o Garatti +23

Mechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planet…

JWST/MIRI observations of the young TWA 27 system: hydrocarbon disk chemistry, silicate clouds, evidence for a CPD

P. Patapis, M. Morales-Calderón, A. M. Arabhavi +39

The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST) enables the characterisation of young self-luminous gas giants at previously inaccessible wavelengths, r…

Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI

S. T. Zeegers, Jonathan P. Marshall, Karl D. Gordon +33

The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reac…

JWST's sharper view of EX Lup: cold water from ice sublimation during accretion outbursts

Sarah A. Smith, Carlos E. Romero-Mirza, Andrea Banzatti +9

The unstable accretion phases during pre-main-sequence evolution of T Tauri stars produce variable irradiation and heating of planet-forming regions. A strong accretion outburst wa…
