The SPACE Program II: No discernible spectral features in the transmission spectrum of the sub-Neptune HD 191939 b observed with HST/WFC3
Cyril Gapp, Lorena Acuña-Aguirre, Reza Ashtari +17
The atmospheres of sub-Neptunes provide a window into their internal structure and history, shedding light on the origin of this common, but enigmatic, class of exoplanets. However…
Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system
Federica Rescigno, Manu Stalport, Ancy Anna John +28
We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…
TOI-2147 b and TOI-6019 b: Two eccentric warm Jupiters detected and characterized with TESS and MaHPS
Luis Thomas, Louise D. Nielsen, Hanna Kellermann +36
The population of Jupiter-sized exoplanets with orbital periods between 10 and 200 days (WJs) exhibits a broad range of orbital eccentricities and system architectures, suggesting…
A distant brown dwarf coplanar to a warm Jupiter and a hot super-Earth
Matías I. Jones, Luca Naponiello, Trifon Trifonov +21
In transiting planetary systems, in which planetary sizes are accurately determined from transit observations, the presence of transit-timing variations (TTVs), especially when com…
A Warm Massive Pair of Planets around TOI-1232 Revealed with Transit-timing Variations and Doppler Spectroscopy
Deyan P. Mihaylov, Jan Eberhardt, Trifon Trifonov +32
TOI-1232 is a G-dwarf star with a mass of , a radius of , and slightly higher metallicity than solar of Fe/H = .…
PLATOSpec's first results: Three new transiting warm Jupiters from the WINE survey TIC 147027702, TIC 245076932 and TIC 87422071
Pavol Gajdoš, Rafael Brahm, Lorena Acuña-Aguirre +33
We report the discovery and characterisation of three transiting warm Jupiters: TIC 147027702b, TIC 245076932b and TIC 87422071b. These systems were initially identified as transit…
The bulk metal content of WASP-80 b from joint interior-atmosphere retrievals: Breaking degeneracies and exploring biases with panchromatic spectra
Lorena Acuña-Aguirre, Laura Kreidberg, Paul Mollière +1
WASP-80 b is an unusually low-density exoplanet in tension with the metal-rich composition expected for a planet of its mass. We aim to derive precise constraints on WASP-80 b's bu…
Evidence of a gap in the envelope mass fraction of sub-Saturns
Luis Thomas, Louise D. Nielsen, Lorena Acuña-Aguirre +1
Under the core-accretion model, gas giants form via runaway accretion. This process starts when the mass of the accreted envelope becomes equal to the mass of the core. Here, we mo…
A transiting hot Jupiter with two outer siblings orbiting an intermediate-mass post main-sequence star
Y. Reinarz, M. I. Jones, R. Brahm +15
Exoplanetary systems with multiple giant planets present an opportunity to understand planet formation, migration processes, and long-term system-wide dynamical interactions. In pa…
TOI-1438: A rare system with two short-period sub-Neptunes and a tentative long-period Jupiter-like planet orbiting a K0V star
Carina M. Persson, Emil Knudstrup, Ilaria Carleo +44
We present the detection and characterisation of the TOI-1438 multi-planet system discovered by TESS. We collected a series of follow-up observations including high-spectral resolu…
On Linking Planet Formation Models, Protoplanetary Disk Properties, and Mature Gas Giant Exoplanet Atmospheres
Adina D. Feinstein, Richard A. Booth, Jennifer B. Bergner +34
Measuring a single elemental ratio (e.g., carbon-to-oxygen) provides insufficient information for understanding the formation mechanisms and evolution that affect our observations…
