Stellar winds can affect gas dynamics in debris disks and create observable belt winds
Quentin Kral, James Pringle, Luca Matrà +1
Context: Gas is now detected in many extrasolar systems around mature stars aged between 10 Myr to 1 Gyr with planetesimal belts. Gas in these mature disks is thought to be…
Peering into the Young Planetary System AB Pic. Atmosphere, Orbit, Obliquity & Second Planetary Candidate
P. Palma-Bifani, G. Chauvin, M. Bonnefoy +24
We aim to revisit the system AB Pic which has a known companion at the exoplanet/ brown-dwarf boundary. We based this study on a rich set of observations to investigate the compani…
Evolution of pits at the surface of 67P/Churyumov-Gerasimenko
Selma Benseguane, Aurélie Guilbert-Lepoutre, Jérémie Lasue +6
The observation of pits at the surface of comets offers the opportunity to take a glimpse into the properties and the mechanisms that shape a nucleus through cometary activity. If…
Is binning always sinning? The impact of time-averaging for exoplanet phase curves
Giuseppe Morello, Achrène Dyrek, Quentin Changeat
We explore how finite integration time or temporal binning can affect the analysis of exoplanet phase-curves. We provide analytical formulae to account for this effect or, if negle…
A photochemical model of Triton's atmosphere with an uncertainty propagation study
B. Benne, M. Dobrijevic, T. Cavalié +2
Triton is the largest satellite of Neptune and probably a Kuiper Belt Object that was captured by the planet. It has a tenuous nitrogen atmosphere similar to the one of Pluto and m…
X-SHYNE: X-shooter spectra of young exoplanet analogs. I. A medium-resolution 0.65-2.5 one-shot spectrum of VHS\,1256-1257 b
Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +10
We present simultaneous 0.65-2.5 microns medium resolution (3300 < R < 8100) VLT/X-Shooter spectra of the young low-mass (19+/-5MJup) L-T transition object VHS 1256-1257 b, a known…
Transit least-squares survey IV. Earth-like transiting planets expected from the PLATO mission
René Heller, Jan-Vincent Harre, Réza Samadi
In its long-duration observation phase, the PLATO satellite will observe two non-overlapping fields for a total of 4 yr. The exact duration of each pointing will be determined 2 yr…
Probing the innermost region of the AU~Microscopii debris disk
A. Gallenne, C. Desgrange, J. Milli +7
AU Mic is a young and nearby M-dwarf star harbouring a circumstellar debris disk and one recently discovered planet on an 8d orbit. Large-scale structures within the disk were also…
Chemical Diversity in Protoplanetary Disks and Its Impact on the Formation History of Giant Planets
Elenia Pacetti, Diego Turrini, Eugenio Schisano +7
Giant planets can interact with multiple and chemically diverse environments in protoplanetary discs while they form and migrate to their final orbits. The way this interaction aff…
Physical properties of the trans-Neptunian object (38628) Huya from a multi-chord stellar occultation
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +85
Within our international program to obtain accurate physical properties of trans-Neptunian objects (TNOs) we predicted a stellar occultation by the TNO (38628) Huya of the star Gai…
A scaled-up planetary system around a supernova progenitor
V. Squicciarini, R. Gratton, M. Janson +24
Virtually all known exoplanets reside around stars with ; to clarify if the dearth of planets around more massive stars is real, we launched the direct-imaging B-sta…
TOI-2046b, TOI-1181b and TOI-1516b, three new hot Jupiters from \textit{TESS}: planets orbiting a young star, a subgiant and a normal star
Petr Kabáth, Priyanka Chaturvedi, Phillip J. MacQueen +54
We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have or…
The JWST Early Release Science Program for the Direct Imaging & Spectroscopy of Exoplanetary Systems
Sasha Hinkley, Aarynn L. Carter, Shrishmoy Ray +83
The direct characterization of exoplanetary systems with high contrast imaging is among the highest priorities for the broader exoplanet community. As large space missions will be…
Interpreting the atmospheric composition of exoplanets: sensitivity to planet formation assumptions
Paul Mollière, Tamara Molyarova, Bertram Bitsch +13
Constraining planet formation based on the atmospheric composition of exoplanets is a fundamental goal of the exoplanet community. Existing studies commonly try to constrain atmosp…
Exocomets size distribution in the Pictoris planetary system
A. Lecavelier des Etangs, L. Cros, G. Hébrard +8
The star Pictoris harbors a young planetary system, which is characterized by the presence of a gaseous and dusty debris disk, at least two massive planets and many minor bodie…
Milliarcsecond astrometry for the Galilean moons using stellar occultations
B. E. Morgado, A. R. Gomes-Júnior, F. Braga-Ribas +40
A stellar occultation occurs when a Solar System object passes in front of a star for an observer. This technique allows the determination of sizes and shapes of the occulting body…
