A possible misaligned orbit for the young planet AU Mic c
H. Yu, Z. Garai, M. Cretignier +98
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measur…
MINDS. JWST-MIRI reveals a peculiar CO-rich chemistry in the drift-dominated disk CX Tau
Marissa Vlasblom, Milou Temmink, Sierra L. Grant +20
Radial drift of icy pebbles can have a large impact on the chemistry of the inner regions of protoplanetary disks. Compact dust disks (50 au) are suggested to have a high…
Combined analysis of the 12.8 and 15 JWST/MIRI eclipse observations of TRAPPIST-1 b
Elsa Ducrot, Pierre-Olivier Lagage, Michiel Min +36
The first JWST/MIRI photometric observations of TRAPPIST-1 b allowed for the detection of the thermal emission of the planet at 15 , suggesting that the planet could be a bare…
CHEOPS observations confirm nodal precession in the WASP-33 system
A. M. S. Smith, Sz. Csizmadia, V. Van Grootel +86
Aims: We aim to observe the transits and occultations of WASP-33b, which orbits a rapidly-rotating Scuti pulsator, with the goal of measuring the orbital obliquity via the grav…
Radii, masses, and transit-timing variations of the three-planet system orbiting the naked-eye star TOI-396
A. Bonfanti, I. Amateis, D. Gandolfi +38
TOI-396 is an F6V star () orbited by three transiting planets. The orbital periods of the two innermost planets are close to the 5:3 commensurability ( d…
A multi-technique detection of an eccentric giant planet around accelerating star HD 57625
D. Barbato, D. Mesa, V. D'Orazi +42
The synergy between different detection methods is a key asset in exoplanetology, allowing for both precise characterization of detected exoplanets and robust constraints even in t…
A joint effort to discover and characterize two resonant mini Neptunes around TOI-1803 with TESS, HARPS-N and CHEOPS
T. Zingales, L. Malavolta, L. Borsato +130
We present the discovery of two mini Neptunes near a 2:1 orbital resonance configuration orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest…
A complete Herbig disk mass survey in Orion
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +3
Disks around intermediate mass stars called Herbig disks are the formation sites of giant exoplanets. Obtaining a complete inventory of these disks will therefore give insights int…
Intermediate mass T Tauri disk masses and a comparison to their Herbig disk descendants
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +3
The precursors of Herbig stars are called Intermediate Mass T Tauri (IMTT) stars, which have spectral types later than F, but stellar masses between 1.5 and 5 M_\odot, and will eve…
The emergence of the Md-Macc correlation in the MHD wind scenario
Luigi Zallio, Giovanni Rosotti, Benoît Tabone +3
There is still much uncertainty around the mechanism that rules the accretion of proto-planetary disks. In the last years, Magnetohydrondynamic (MHD) wind-driven accretion has been…
Magnetic Field Evolution of Hot Exoplanets
Konstantinos Kilmetis, Aline A. Vidotto, Andrew Allan +1
Numerical simulations have shown that the strength of planetary magnetic fields depends on the convective energy flux emerging from planetary interiors. Here we model the interior…
Detection and Characterisation of Giant Planets with Gaia Astrometry
A. L. Wallace, A. R. Casey, A. G. A. Brown +1
Astrometric observations with Gaia are expected to play a valuable role in future exoplanet surveys. With current data from Gaia's third data release (DR3), we are sensitive to per…
Diversities and similarities exhibited by multi-planetary systems and their architectures: I. Orbital spacings
Alexandra Muresan, Carina Persson, Malcolm Fridlund
The rich diversity of multi-planetary systems and their architectures is greatly contrasted by the uniformity exhibited within many of these systems. Previous studies have shown th…
Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood
Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62
The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
Water depletion and 15NH3 in the atmosphere of the coldest brown dwarf observed with JWST/MIRI
H. Kühnle, P. Patapis, P. Mollière +21
With a temperature of K WISE0855 is the coldest brown dwarf observed so far. Using the James Webb Space Telescope (JWST) we obtained observations that allow us to charac…
Atmospheric escape in hot Jupiters under sub-Alfvénic interactions
Andrés Presa, Florian A. Driessen, Aline A. Vidotto
Hot Jupiters might reside inside the Alfvén surface of their host star wind, where the stellar wind is dominated by magnetic energy. The implications of such a sub-Alfvénic environ…
On the origin of transition disk cavities: Pebble-accreting protoplanets vs Super-Jupiters
Shuo Huang, Nienke van der Marel, Simon Portegies Zwart
Protoplanetary disks surrounding young stars are the birth places of planets. Among them, transition disks with inner dust cavities of tens of au are sometimes suggested to host ma…
Giant planets population around B stars from the first part of the BEAST survey
P. Delorme, A. Chomez, V. Squicciarini +23
Exoplanets form from circumstellar protoplanetary discs whose fundamental properties (notably their extent, composition, mass, temperature and lifetime) depend on the host star pro…
The K2-24 planetary system revisited by CHEOPS
V. Nascimbeni, L. Borsato, P. Leonardi +82
K2-24 is a planetary system composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large TTVs, i.e., an excellent laboratory to sea…
Trajectory of the stellar flyby that shaped the outer solar system
Susanne Pfalzner, Amith Govind, Simon Portegies Zwart
Unlike the Solar System planets, thousands of smaller bodies beyond Neptune orbit the Sun on eccentric ( 0.1) and ( 3) orbits. While migration of the giant planets…
Gravitational instability in a planet-forming disk
Jessica Speedie, Ruobing Dong, Cassandra Hall +7
The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes…
