Observing a 542-day transiting giant with large TTVs: The 2025 transit of HIP 41378 f and new constraints on the outer system
Pietro Leonardi, Alexandre Santerne, Luca Borsato +27
Characterizing long-period transiting exoplanets is inherently challenging due to the rarity and long duration of transit events. Yet, these systems provide unique insights into pl…
The breaking of cold traps and onset of titanium in ultra-hot Jupiter atmospheres: WASP-189b in context
Stefan Pelletier, Romain Allart, Valentina Vaulato +56
Condensates are ubiquitous to all Solar System planets with significant (10mbar) atmospheres. The same is true for most exoplanets with characterised atmospheres, with even ultr…
Next-generation Exo-REM atmospheric models: application to VHS 1256 b to emulate patchy clouds
Alice Radcliffe, Benjamin Charnay, Anne-Marie Lagrange +7
Condensate clouds are a defining feature of brown dwarf and exoplanet atmospheres, producing a broad range of colours on the CMD and giving rise to spectral features such as the di…
Destructuring the disk of AB Aurigae: Dynamics and accretion
Anthony Boccaletti, Emmanuel Di Folco, Anne Dutrey +23
In this paper, we present near-IR polarized images of the AB Aur disk at three epochs spanning 3.85 years with SPHERE/IRDIS, as well as Halpha images obtained with SPHERE/ZIMPOL at…
Towards Doppler eclipse mapping of hot Jupiters. An observational perspective on WASP-33 b with SPIRou
Vincent Yariv, Xavier Bonfils, Nicolas Cowan +7
In the last decade, ground-based high-resolution spectroscopy (HRS) has emerged as a powerful method to probe exoplanet atmospheres both in transit and thermal emission. With HRS s…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains
J. Olofsson, M. R. Jankovic, S. Marino +22
The dust observed in debris disks is the result of a collisional cascade initiated from km-sized parent bodies. Using near-infrared to sub-millimeter observations, we can pr…
Astrochemical Inheritance of Terrestrial Planets Water from Local Wet Silicates
Lise Boitard-Crépeau, Stefano Pantaleone, Cecilia Ceccarelli +3
The delivery of water to the inner Solar System rocky planets, including Earth, remains debated, as standard models assume that they formed from dry grains, inside the snowline of…
Exploration of the inner region of the system HD 142527
T. M. H. Tran, M. Langlois, O. Flasseur +6
HD 142527 is a well-studied intermediate-mass T Tauri star surrounded by a transitional disk with a large dust cavity, spiral structures, and an accreting low-mass companion. Despi…

Gayathri Viswanath, Mickaël Bonnefoy, Catherine Dougados +8
High-resolution spectroscopic observations of helium emission lines provide a powerful probe of accretion geometry in classical T Tauri stars, revealing regions not well traced by…
Weighing the mass of LHS 3844 b
Alejandro Hacker, Nicola Astudillo-Defru, Rodrigo F. Díaz +7
Context: LHS 3844 b (TOI-136 b) is a ultra short-period, Earth-size exoplanet detected by TESS. It is one of the most favourable object for atmospheric characterisation and the stu…
