A Framework to Model Stellar Irradiated Disks with Frequency-dependent Absorption and Scattering Opacities in Athena++
Stanley A. Baronett, Yan-Fei Jiang, Zhaohuan Zhu +2
The frequency dependence of opacity is crucial for determining the thermal structure of protoplanetary disks, which in turn influences disk dynamics and planet formation. Yet many…
Shadow-Induced Warps in Protoplanetary disks
Shangjia Zhang, Zhaohuan Zhu, Callum W. Fairbairn
Shadows are commonly observed in protoplanetary disks in near-infrared and (sub)millimeter images, often cast by misaligned inner disks or other obscuring material. While recent st…
JWST/NIRCam Coronagraphic Search for Hidden Planets in the HD~163296 Protoplanetary Disk
Taichi Uyama, Luca Ricci, Marie Ygouf +10
HD~163296 is a Herbig Ae/Be star with multiple signposts of on-going planet formation on its disk, such as prominent rings and gaps, as well as kinematic features as identified by…
High Resolution ALMA Observations of Richly Structured Protoplanetary Disks in Orionis
Jane Huang, Megan Ansdell, Tilman Birnstiel +5
ALMA has detected substructures in numerous protoplanetary disks at radii from a few to over a hundred au. These substructures are commonly thought to be associated with planet for…
3D Radiation-Hydrodynamical Simulations of Shadows on Transition Disks
Shangjia Zhang, Zhaohuan Zhu
Shadows are often observed in transition disks, which can result from obscuring by materials closer to the star, such as a misaligned inner disk. While shadows leave apparent darke…
A Survey of Protoplanetary Disks Using the Keck/NIRC2 Vortex Coronagraph
Nicole L. Wallack, Jean-Baptiste Ruffio, Garreth Ruane +34
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spira…
