GeoCache: Training-Free Acceleration of Multi-View Texture Diffusion via Geometric Delta Transport
Haotang Li, Zhenyu Qi, Shaohan Henry Wang +6
Geometry-conditioned multi-view diffusion enables high-quality 3D texture generation, but its repeated per-view denoiser evaluations introduce substantial computational cost. Exist…
ALMA 873 m Polarization Observations of the PDS~70 Disk
Hauyu Baobab Liu, Kiyoaki Doi, Simon Casassus +4
At a 112.4 pc distance, the PDS70 protoplanetary disk is a rare case that has been confirmed to host two accreting planets. This makes it the most important laboratory for studying…
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…
Multi-frequency observations of PDS 70c: Radio emission mechanisms in the circum-planetary environment
Oriana DomÃnguez-Jamett, Simon Casassus, Hauyu Baobab Liu +7
PDS 70c is a source of Ha emission and variable sub-mm signal. Understanding its emission mechanisms may enable observations of accretion rates and physical conditions in the circu…
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…
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…
