Detecting false positives with PLATO using double-aperture photometry and centroid shifts
F. Gutiérrez-Canales, R. Samadi, A. Birch +6
PLATO will discover exoplanets around Sun-like stars through transit photometry and characterize their host stars using asteroseismology. Since photometry for most PLATO targets wi…
Time-resolved X-ray spectra of Proxima Centauri as seen by XMM-Newton
A. Damonte, I. Pillitteri, A. Maggio +2
Stellar soft X-ray ([1, 100] Angstrom) and Extreme Ultraviolet (also EUV, [100, 920] Angstrom; jointly, XUV) radiation affects the evolution and chemistry of exoplanet atmospheres.…
Characterization of debris disks observed with SPHERE
N. Engler, J. Milli, N. Pawellek +33
This study aims to characterize debris disks observed with SPHERE across multiple programs, with the goal of identifying systematic trends in disk morphology, dust mass, and grain…
Interstellar Ices as Carriers of Supernova Material to the Early Solar System
Martin Bizzarro, Martin Schiller, Jesper Holst +10
Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiti…
Exomoon search with VLTI/GRAVITY around the substellar companion HD 206893 B
Q. Kral, J. Wang, J. Kammerer +130
Direct astrometric detection of exomoons remains unexplored. This study presents the first application of high-precision astrometry to search for exomoons around substellar compani…
Rapid-response characterization of near-Earth asteroid 2024 YR4 during a Torino Scale 3 alert
Maxime Devogèle, Olivier R. Hainaut, Marco Micheli +32
On 27 December 2024, near-Earth object (NEO) 2024 YR was discovered by the ATLAS survey and identified as a virtual impactor. A few weeks later, it eventually reached level 3 o…
Ringed versus Ringless Worlds: How Poynting-Robertson Drag Shapes Rings across the Solar System
Ryuki Hyodo, Shigeru Ida
Planetary rings are not only ubiquitous around the giant planets in the outer Solar System, but have also been discovered around several small distant bodies. In contrast, no rings…
Experiments reveal extreme water generation during planet formation
Francesca Miozzi, Anat Shahar, Edward D. Young +7
The most abundant type of planet discovered in the Galaxy has no analogue in our Solar System and is believed to consist of a rocky interior with an overlying thick H2 dominated en…
The MATISSE view of the inner region of the RY Tau protoplanetary disk
J. S. Martin, J. Kobus, J. Varga +44
The T-Tauri type young stellar object RY Tau exhibits a dust depleted inner cavity characteristic of a transition disk. We constrain the spatial distribution and mineralogy of dust…
The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
The resilience of the sailboat stable region
Rafael Sfair, Tiago F. L. L. Pinheiro, Giovana Ramon +1
Binary systems host complex orbital dynamics where test particles can occupy stable regions despite strong gravitational perturbations. The sailboat region, discovered in the Pluto…
Rings around irregular bodies I. Structure of the resonance mesh, applications to Chariklo, Haumea and Quaoar
Bruno Sicardy, Heikki Salo, Maryame El Moutamid +2
Three ring systems have been discovered to date around small irregular objects of the solar system (Chariklo, Haumea and Quaoar). For the three bodies, material is observed near th…
Impact of Charge Transfer Inefficiency on transit light-curves: A correction strategy for PLATO
Shaunak Mishra, Reza Samadi, Diane Bérard
PLATO is designed to detect Earth-sized exoplanets around solar-type stars and to measure their radii with accuracy better than \(2\%\) via the transit method. Charge transfer inef…
Discovery of carbon monoxide emission from five debris disks around young A-type stars
A. Moór, P. Ábrahám, Á +7
Over the past fifteen years, surveys mainly at millimeter wavelengths have led to the discovery of 20 gas-bearing debris disks, most of them surrounding young intermediate-ma…
ATREIDES I. Embarking on a trek across the exo-Neptunian landscape with the TOI-421 system
V. Bourrier, M. Steiner, A. Castro-González +75
The distribution of close-in exoplanets is shaped by the interplay between atmospheric and dynamical processes. The Neptunian Desert, Ridge, and Savanna illustrate the sensitivity…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
Deimos photometric properties: analysis of 20 years of observations (2004-2024) by the Mars Express HRSC camera
A. Wargnier, P. N. Simon, S. Fornasier +6
The goal of this study is to analyze the photometric properties of Deimos using Mars Express (MEX) observations, to improve the photometric properties and provide new insights into…
New constraint on Europa's ice shell: magnetic signature from the ocean
