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…

Discovery of H Emission from a Protoplanet Candidate Around the Young Star 2MASS J16120668-3010270 with MagAO-X

Jialin Li, Laird M. Close, Feng Long +32

2MASS J16120668-3010270 (hereafter 2MJ1612) is a young M0 star that hosts a protoplanetary disk in the Upper Scorpious star-forming region. Recent ALMA observations of 2MJ1612 show…

exoALMA XI: ALMA Observations and Hydrodynamic Models of LkCa 15: Implications for Planetary Mass Companions in the Dust Continuum Cavity

Charles H. Gardner, Andrea Isella, Hui Li +43

In the past decade, the Atacama Large Millimeter/submillimeter Array (ALMA) has revealed a plethora of substructures in the disks surrounding young stars. These substructures have…

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…

Thermal Structure Determines Kinematics: Vertical Shear Instability in Stellar Irradiated Protoplanetary Disks

Shangjia Zhang, Zhaohuan Zhu, Yan-Fei Jiang

Turbulence is crucial for protoplanetary disk dynamics, and Vertical Shear Instability (VSI) is a promising mechanism in outer disk regions to generate turbulence. We use Athena++…

ALMA Detection of Dust Trapping around Lagrangian Points in the LkCa 15 Disk

Feng Long, Sean M. Andrews, Shangjia Zhang +10

We present deep high-resolution (50 mas, 8 au) ALMA 0.88 and 1.3 mm continuum observations of the LkCa 15 disk. The emission morphology shows an inner cavity and three dust r…
