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…
Early Planet Formation in Embedded Disks (eDisk). XX. Constraining the Chemical Tracers of Young Protostellar Sources
Rajeeb Sharma, Jes K. Jørgensen, Merel L. R. van 't Hoff +12
Recent studies indicate that the formation of planets in protoplanetary disks begins early in the embedded Class 0/I phases of protostellar evolution. The physical and chemical mak…
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…
JCMT detection of HCN emission from 3I/ATLAS at 2.1 AU
Iain M. Coulson, Yi-Jehng Kuan, Steven B. Charnley +8
We report the detection of HCN () rotational emission from comet 3I/ATLAS at a heliocentric distance of 2.13 AU with the James Clerk Maxwell Telescope (JCMT). Observations w…
Edge-On Disk Study (EODS) III: Molecular Stratification in the Flying Saucer Disk
A. Dutrey, O. Denis-Alpizar, S. Guilloteau +22
Context: Investigating the vertical distribution of molecular content in protoplanetary disks remains difficult in most disks mildly inclined along the line of sight. In contrast,…
YSES 2b is a background star: Differential astrometric M-dwarf measurements in time
Matthew Kenworthy, Tomas Stolker, Jens Kammerer +13
We wish to confirm the nature of YSES 2b, a purportedly faint companion of the young star YSES 2. We used on-sky observations from SPHERE and GRAVITY to measure the astrometric pos…
Multi-modal atmospheric characterization of Pictoris b: Adding high-resolution continuum spectra from GRAVITY
M. Ravet, M. Bonnefoy, G. Chauvin +24
We present the first VLTI/GRAVITY observations at R of Pic b. These four high S/N (20) K-band spectra conserve both the pseudo-continuum and molecular absorp…
Testing the Impact of Planet-stirring, Self-stirring, and Mixed-stirring on Debris Disc Architecture: A Case Study of HD 16743
Jonathan P. Marshall, Marco A. Muñoz-Gutiérrez, Antranik A. Sefilian +1
Dynamical interactions between planets and debris discs can excite the orbits of embedded planetesimals to such a degree that a collisional cascade is triggered, generating detecta…
Discovery and dynamics of a Sedna-like object with a perihelion of 66 au
Ying-Tung Chen, Patryk Sofia Lykawka, Yukun Huang +30
Trans-Neptunian objects (TNOs) with large perihelion distances ( au) and semi-major axes ( au) provide insights into the early evolution of the solar system and th…
Hydrodynamical simulations of the vertical shear instability with dynamic dust and cooling rates in protoplanetary disks
Yuya Fukuhara, Mario Flock, Satoshi Okuzumi +1
Turbulence in protoplanetary disks affects dust evolution and planetesimal formation. The vertical shear instability (VSI) is one of the candidate turbulence-driving mechanisms in…
Edge-On Disk Study (EODS) II: Thermal Structure of the Flying Saucer Disk
S. Guilloteau, O. Denis-Alpizar, A. Dutrey +21
Context. The dust and gas temperature in proto-planetary disks play critical roles in determining their chemical evolution and influencing planet formation processes. Aims. We atte…
Osiris revisited: Confirming a solar metallicity and low C/O in HD 209458b
N. Bachmann, L. Kreidberg, P. Mollière +2
HD 209458b is the prototypical hot Jupiter and one of the best targets available for precise atmosphere characterisation. Now that spectra from both Hubble Space Telescope (HST) an…
Dust Growth in ALMA Rings: II. Dusty Rossby Wave Instability
Can Cui, Konstantin Gerbig, Ya-Ping Li +5
Annular substructures serve as ideal venues for planetesimal formation. In this series, we investigate the linear stage of dust growth within rings. The first paper examines the gl…
exoALMA. XVII. Characterizing the Gas Dynamics around Dust Asymmetries
Lisa Wölfer, Marcelo Barraza-Alfaro, Richard Teague +31
The key planet-formation processes in protoplanetary disks remain an active matter of research. One promising mechanism to radially and azimuthally trap millimeter-emitting dust gr…
