The Inbound Gas and Dust Evolution of Interstellar Comet 3I/ATLAS from Optical Spectroscopy and Multi-band Photometry
Toni Santana-Ros, Alexey Sergeyev, Oleksandra Ivanova +9
Interstellar objects (ISOs) provide direct constraints on the composition and evolution of extrasolar planetary systems. As the third confirmed ISO, comet 3I/ATLAS offers a rare op…
Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
The paper reports the direct imaging discovery of a third giant exoplanet, β Pictoris d, using VLT/ERIS and archival JWST/NIRCam and VLT/SPHERE data, and characterizes its orbit, t…
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…
The Neptunian ridge as a natural outcome of high-eccentricity tidal migration
A. Castro-González, V. Bourrier, D. Ehrenreich +3
Recent occurrence-rate analyses have shown that the transition between the Neptunian desert and the savanna is not smooth but instead exhibits an overdensity of planets at $P_{\rm…
Equilibrium figure of Haumea and possible detection by stellar occultation
C. Staelen, N. Rambaux, F. Chambat +1
The equilibrium figure of dwarf planet Haumea is studied to determine if the observed shape is compatible with a differentiated hydrostatic body. Three groups of interior models of…
Euclid: Asteroid rotation periods from the Euclid Ecliptic Survey
B. Y. Irureta-Goyena, B. Altieri, J. -P. Kneib +142
The Euclid Ecliptic Survey was conducted during the calibration phase of the mission, 23-31 December 2023, as a campaign to study Solar System objects. We used data from this surve…
