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…
Large-amplitude Variability Driven by Giant Dust Storms on a Planetary-mass Companion
Xianyu Tan, Xi Zhang, Mark S. Marley +17
Large-amplitude variations are commonly observed in the atmospheres of directly imaged exoplanets and brown dwarfs. VHS 1256B, the most variable known planet-mass object, exhibits…
Improved characterization of the TOI-2141 system: a dense sub-Neptune with non-transiting inner and outer companions
R. Luque, K. W. F. Lam, J. Cabrera +87
We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star in a relatively long orbit of 18.26 d…
The model for cloudy substellar atmospheres: A grid of self-consistent substellar atmosphere models with microphysical cloud formation
Beatriz Campos Estrada, David A. Lewis, Christiane Helling +3
State-of-the-art JWST observations are unveiling unprecedented views into the atmospheres of substellar objects in the infrared, further highlighting the importance of clouds. Curr…
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…
Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS
Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33
We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…
The first scattered light images of HD 112810, a faint debris disk in the Sco-Cen association
Elisabeth C. Matthews, Mickaël Bonnefoy, Chen Xie +17
Context: Circumstellar debris disks provide insight into the formation and early evolution of planetary systems. Resolved belts in particular help to locate planetesimals in exosys…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems II: A 1 to 20 Micron Spectrum of the Planetary-Mass Companion VHS 1256-1257 b
Brittany E. Miles, Beth A. Biller, Polychronis Patapis +101
We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a 20 M widely separated (8\arcsec, a = 150 au), young, planetary-…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems I: High Contrast Imaging of the Exoplanet HIP 65426 b from 2-16 m
Aarynn L. Carter, Sasha Hinkley, Jens Kammerer +108
We present JWST Early Release Science (ERS) coronagraphic observations of the super-Jupiter exoplanet, HIP 65426 b, with the Near-Infrared Camera (NIRCam) from 2-5 m, and with t…
Signs of late infall and possible planet formation around DR Tau using VLT/SPHERE and LBTI/LMIRCam
D. Mesa, C. Ginski, R. Gratton +31
Context. Protoplanetary disks around young stars often contain substructures like rings, gaps, and spirals that could be caused by interactions between the disk and forming planets…
An HST/STIS View of Protoplanetary Disks in Upper Scorpius: Observations of Three Young M-Stars
Samuel Walker, Maxwell Millar-Blanchaer, Bin Ren +2
We present observations of three protoplanetary disks in visible scattered light around M-type stars in the Upper Scorpius OB association using the STIS instrument on the Hubble Sp…
The SPHERE infrared survey for exoplanets (SHINE) -- II. Observations, Data reduction and analysis Detection performances and early-results
M. Langlois, R. Gratton, A. -M. Lagrange +118
Over the past decades, direct imaging has confirmed the existence of substellar companions (exoplanets or brown dwarfs) on wide orbits (>10 au) from their host stars. To understand…
A High-Contrast Search for Variability in HR 8799bc with VLT-SPHERE
B. A. Biller, D. Apai, M. Bonnefoy +11
The planets HR8799bc display nearly identical colours and spectra as variable young exoplanet analogues such as VHS 1256-1257ABb and PSO J318.5-22, and are likely to be similarly v…
The SPHERE infrared survey for exoplanets (SHINE). III. The demographics of young giant exoplanets below 300 au with SPHERE
A. Vigan, C. Fontanive, M. Meyer +108
The SHINE project is a 500-star survey performed with SPHERE on the VLT for the purpose of directly detecting new substellar companions and understanding their formation and early…
Micrometeoroid Events in LISA Pathfinder
James Ira Thorpe, Jacob Slutsky, John Baker +104
The zodiacal dust complex, a population of dust and small particles that pervades the Solar System, provides important insight into the formation and dynamics of planets, comets, a…
On fragmentation of turbulent self-gravitating discs in the long cooling time regime
Ken Rice, Sergei Nayakshin
It has recently been suggested that in the presence of driven turbulence discs may be much less stable against gravitational collapse than their non turbulent analogs, due to stoch…
On the fragmentation boundary in magnetised self-gravitating discs
Duncan Forgan, Daniel J. Price, Ian Bonnell
We investigate the role of magnetic fields in the fragmentation of self-gravitating discs using 3D global ideal magnetohydrodynamic simulations performed with the "phantom" smoothe…
Milankovitch Cycles of Terrestrial Planets in Binary Star Systems
Duncan H Forgan
The habitability of planets in binary star systems depends not only on the radiation environment created by the two stars, but also on the perturbations to planetary orbits and rot…
Atmospheric electrification in dusty, reactive gases in the solar system and beyond
Ch. Helling, R. G. Harrison, F. Honary +7
Detailed observations of the solar system planets reveal a wide variety of local atmospheric conditions. Astronomical observations have revealed a variety of extrasolar planets non…
Exomoon Climate Models with the Carbonate-Silicate Cycle and Viscoelastic Tidal Heating
Duncan Forgan, Vera Dobos
The habitable zone for exomoons with Earth-like properties is a non-trivial manifold, compared to that of Earth-like exoplanets. The presence of tidal heating, eclipses and planeta…
Disc fragmentation rarely forms planetary-mass objects
Ken Rice, Eric Lopez, Duncan Forgan +1
It is now reasonably clear that disc fragmentation can only operate in the outer parts of protostellar discs ( au). It is also expected that any object that forms via disc…
