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…
SCExAO/CHARIS and Gaia Direct Imaging and Astrometric Discovery of a Superjovian Planet 3--4 lambda/D from the Accelerating Star HIP 54515
Thayne Currie, Yiting Li, Mona El Morsy +28
We present the discovery of a superjovian planet around the young A5 star HIP 54515, detected using precision astrometry from the Hipparcos Gaia Catalogue of Accelerations and high…
OASIS Survey Direct Imaging and Astrometric Discovery of HIP 71618 B: A Substellar Companion Suitable for the Roman Coronagraph Technology Demonstration
Mona El Morsy, Thayne Currie, Brianna Lacy +27
We present the OASIS survey program discovery of a substellar companion orbiting the young A1V star HIP 71618, detected using precision astrometry from Gaia and Hipparcos and high-…
A tale of three tails: A misaligned streamer and mysterious structures around [BHB2007]1
Aashish Gupta, Antonio S. Hales, L. Ilsedore Cleeves +8
Recent discoveries of streamer-like structures around protostellar sources challenge the traditional picture of isolated, axisymmetric star formation. Here, we present new ALMA obs…
Resolving the large exoKuiper belt of the HD 126062 debris disc and extended gas emission in its vicinity
James M. Miley, Grant M. Kennedy, Alvaro Ribas +8
Intermediate-mass stars (1-3 Msun) host some of the brightest and best-studied debris discs. This stellar class is also the most frequent host of molecular gas in systems older tha…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): V721 CrA and BN CrA have wide and structured disks in polarised IR
Gabriele Columba, Elisabetta Rigliaco, Raffaele Gratton +8
We present near-infrared scattered-light observations of the disks around two stars of the Corona Australis star-forming region, V721 CrA, and BN CrA, obtained with VLT/SPHERE, in…
New Orbital Constraints for YSES 1 b and HR 2562 B from High-Precision Astrometry and Planetary Radial Velocities
Jonathan Roberts, William Thompson, Jason J. Wang +20
We present new VLTI/GRAVITY astrometry and updated orbit fits for the directly imaged companions YSES 1 b and HR 2562 B, substellar objects straddling the planet-brown dwarf bounda…
X-SHYNE: X-Shooter spectra of young exoplanet analogs II. Presentation and analysis of the full library
Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +29
The X-SHYNE library is a homogeneous sample of 43 medium-resolution (R=8000) infrared (0.3-2.5um) spectra of young (<500Myr), low-mass (<20Mjup), and cold (Teff=600-2000K) isolated…
VLT/ERIS observations of the V960 Mon system: a dust-embedded substellar object formed by gravitational instability?
Anuroop Dasgupta, Alice Zurlo, Philipp Weber +8
V960~Mon is an FU Orionis object that shows strong evidence of a gravitationally unstable spiral arm that is fragmenting into several dust clumps. We report the discovery of a new…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): Evidence of planet-disk interaction in the 2MASSJ16120668-3010270 system
C. Ginski, P. Pinilla, M. Benisty +28
The architectures of exoplanet systems are likely set during the initial planet-formation phase in the circumstellar disk. To understand this process, we have to study the earliest…
Protoplanetary disk insights from the first ERIS/APP survey at 4 μm
F. Maio, V. Roccatagliata, D. Fedele +17
We present high-contrast imaging observations of seven protoplanetary disks at 4um using the ERIS on the VLT. This study focuses on detecting scattered light from micron-sized dust…
The Ophiuchus DIsk Survey Employing ALMA (ODISEA): A Unified Evolutionary Sequence of Planet-Driven Substructures Explaining the Diversity of Disk Morphologies
Santiago Orcajo, Lucas A. Cieza, Octavio Guilera +21
Understanding the origin of substructures in protoplanetary disks and their connection to planet formation is currently one of the main challenges in astrophysics. While some disks…
A Multi-Wavelength Study of the Dynamic Environment surrounding the FUor V960 Mon
Philipp Weber, Silvio Ulloa, Sebastián Pérez +11
The evolution of young stars and planet-forming environments is intrinsically linked to their nascent surroundings. This is particularly evident for FU Orionis (FUor) objectsa c…
