Color measurements of the polarized light scattered by the dust in protoplanetary disks
J. Ma, H. M. Schmid, T. Stolker
Ground-based high-contrast instruments have yielded reflected light images of protoplanetary disks. Quantitative measurements of the reflected radiation provide strong constraints…
The origin and evolution of wide Jupiter Mass Binary Objects in young stellar clusters
Simon Portegies Zwart, Erwan Hochart
The recently observed population of 540 free-floating Jupiter-mass objects, including 40 dynamically soft pairs in the Trapezium cluster have raised interesting questions on their…
A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
A Near-infrared Variability Survey of Young Planetary-mass Objects
Pengyu Liu, Beth A. Biller, Johanna M. Vos +12
We present a photometric variability survey of young planetary-mass objects using the New Technology Telescope in the Js and Ks bands. Surface gravity plays an important role in th…
15NH3 in the atmosphere of a cool brown dwarf
David Barrado, Paul Mollière, Polychronis Patapis +40
Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits as the governing physical and chemical processes in them are nearly identic…
SO2, silicate clouds, but no CH4 detected in a warm Neptune
Achrene Dyrek, Michiel Min, Leen Decin +44
WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…
Evolution of helium triplet transits of close-in gas giants orbiting K-dwarfs
Andrew P. Allan, Aline A. Vidotto, Carolina Villarreal D'Angelo +2
Atmospheric escape in exoplanets has traditionally been observed using hydrogen Lyman- and H- transmission spectroscopy, but more recent detections have utilised the metastab…
A hybrid approach for solving the gravitational N-body problem with Artificial Neural Networks
Veronica Saz Ulibarrena, Philipp Horn, Simon Portegies Zwart +3
Simulating the evolution of the gravitational N-body problem becomes extremely computationally expensive as N increases since the problem complexity scales quadratically with the n…
The sulphur species in hot rocky exoplanet atmospheres
L. J. Janssen, P. Woitke, O. Herbort +4
The first JWST observations of hot Jupiters showed an unexpected detection of SO2 in their hydrogen-rich atmospheres. We investigate how much sulphur can be expected in the atmosph…
No random transits in CHEOPS observations of HD 139139
R. Alonso, S. Hoyer, M. Deleuil +78
HD 139139 (a.k.a. 'The Random Transiter') is a star that exhibited enigmatic transit-like features with no apparent periodicity in K2 data. The shallow depth of the events (2…
Composition and thermal properties of Ganymede's surface from JWST/NIRSpec and MIRI observations
D. Bockelee-Morvan, E. Lellouch, O. Poch +21
JWST NIRSpec IFU (2.9-5.3 mu) and MIRI MRS (4.9-28.5 mu) observations were performed on both the leading and trailing hemispheres of Ganymede with a spectral resolution of ~2700. R…
Imaging detection of the inner dust belt and the four exoplanets in the HR8799 system with JWST's MIRI coronagraph
Boccaletti A., Mâlin M., Baudoz P. +35
The multi planet system HR8799 is the first target observed with MIRI's coronagraphs as part of the MIRI-EC Guaranteed Time Observations exoplanets programme in Nov. 2022. We obtai…
IRAS4A1: Multi-wavelength continuum analysis of a very flared Class 0 disk
O. M. Guerra-Alvarado, N. van der Marel, J. Di Francesco +7
Understanding the formation of substructures in protoplanetary disks is vital for gaining insights into dust growth and the process of planet formation. Studying these substructure…
Euclid: Identification of asteroid streaks in simulated images using deep learning
M. Pöntinen, M. Granvik, A. A. Nucita +114
Up to 150000 asteroids will be visible in the images of the ESA Euclid space telescope, and the instruments of Euclid offer multiband visual to near-infrared photometry and slitles…
Dust evolution in protoplanetary disks
Nienke van der Marel, Paola Pinilla
Planet formation models rely on knowledge of the physical conditions and evolutionary processes in protoplanetary disks, in particular the grain size distribution and dust growth t…
Refining the properties of the TOI-178 system with CHEOPS and TESS
L. Delrez, A. Leleu, A. Brandeker +84
The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with orbital periods between 1.9 and 20.7 days. All planets…
Radio multiwavelength analysis of the compact disk CX Tau: Presence of strong free-free variability or anomalous microwave emission
Pietro Curone, Leonardo Testi, Enrique Macias +8
Protoplanetary disks emit radiation across a broad range of wavelengths, requiring a multiwavelength approach to fully understand their physical mechanisms and how they form planet…
Tracing snowlines and C/O ratio in a planet-hosting disk: ALMA molecular line observations towards the HD169142 disk
Alice S. Booth, Charles J. Law, Milou Temmink +2
The composition of a forming planet is set by the material it accretes from its parent protoplanetary disk. Therefore, it is crucial to map the chemical make-up of the gas in disks…
Impacts of high-contrast image processing on atmospheric retrievals
Evert Nasedkin, Paul Mollière, Jason Wang +5
Many post-processing algorithms have been developed in order to better separate the signal of a companion from the bright light of the host star, but the effect of such algorithms…
The Chemical Inventory of the Inner Regions of Planet-forming Disks -- The JWST/MINDS Program
Inga Kamp, Thomas Henning, Aditya M. Arabhavi +40
