Astrometric view of companions in the inner dust cavities of protoplanetary disks
Miguel Vioque, Richard A. Booth, Enrico Ragusa +16
Protoplanetary disks with inner dust cavities (often referred to as "transition disks") are potential signposts of planet formation. We use Gaia astrometry to search for planetary…
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…
Observational evidence for a possible link between PAH emission and dust trap locations in protoplanetary disks
Nienke van der Marel, Niels F. W. Ligterink, Ryan van der Werf +4
Polycyclic Aromatic Hydrocarbons (PAHs) are commonly detected in protoplanetary disks, but it is unclear what causes the wide range of intensities across the samples. In this work,…
Mass determination of the three long-period Neptune- and sub-Neptune-sized planets transiting TOI-282
A. Barone, F. Rodler, D. Gandolfi +16
TOI-282 is a bright (V=9.38) F8 main-sequence star known to host three transiting long-period (=22.9 d, =56.0 d, and =84.3 d) small ( 2-4 ) p…
Chasing the storm: Investigating the application of high-contrast imaging techniques in producing precise exoplanet light curves
Ben J. Sutlieff, David S. Doelman, Jayne L. Birkby +10
Substellar companions such as exoplanets and brown dwarfs exhibit changes in brightness arising from top-of-atmosphere inhomogeneities, providing insights into their atmospheric st…
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…
Photoevaporation Can Reproduce Extended Emission from Protoplanetary Disks Imaged by JWST MIRI
R. Nakatani, G. Rosotti, B. Tabone +1
Understanding dispersal of protoplanetary disks remains a central challenge in planet formation theory. Disk winds, driven by magnetohydrodynamics (MHD) and/or photoevaporation, ar…
The effects of stellar activity cycles on planetary atmospheric escape and the HeI 1083nm transit signature
Andrew P. Allan, Aline A. Vidotto, Jorge Sanz-Forcada +1
The HeI 1083nm transit signature is commonly used in tracing escaping planetary atmospheres. However, it can be affected by stellar activity, complicating detections and interpreta…
Molecular line emission from 1000 au scales outflows to <30 au compact structures in NGC1333 IRAS4A2
Osmar M. Guerra-Alvarado, N. van der Marel, P. Nazari +6
Aims. Studying protostellar objects in their earliest stages, particularly during the Class 0 phase, provides key insight into the beginnings of planet formation and dust evolution…
From gas to ice giants: A unified mechanism for equatorial jets
Keren Duer-Milner, Nimrod Gavriel, Eli Galanti +2
The equatorial jets dominating the dynamics of the Jovian planets exhibit two distinct types of zonal flows: strongly eastward in the gas giants (superrotation) and strongly westwa…
The ExoGRAVITY survey: A K-band spectral library of giant exoplanet and brown dwarf companions
J. Kammerer, T. O. Winterhalder, S. Lacour +106
Direct observations of exoplanet and brown dwarf companions with near-infrared interferometry, first enabled by the dual-field mode of VLTI/GRAVITY, provide unique measurements of…
MINDS: The very low-mass star and brown dwarf sample II. Probing disk settling, dust properties, and dust-gas interplay with JWST/MIRI
Hyerin Jang, Aditya M. Arabhavi, Till Kaeufer +11
Disks around very low-mass stars (VLMS) provide environments for the formation of Earth-like planets. Mid-infrared observations have revealed that these disks exhibit weak silicate…
New migration patterns in high planet-star mass ratio systems in disks with low viscosity
Mariana Sánchez, Sijme-Jan Paardekooper, Nienke van der Marel +2
Migration of giant planets remains a complex topic. While significant progress has been made for high-viscosity disks, the migration of planets with large planet-star mass ratios i…
Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b
S. Ulmer-Moll, S. Gill, R. Brahm +64
Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…
