Infrared Echoes of Precessing Tidal Disruption Events
Hong-Zhou Wu, Shao-Yu Fu, Wen-Long Xu +2
A tidal disruption event (TDE) occurs when a star is torn apart by a supermassive black hole. The resulting UV/optical flare irradiates parsec-scale dust, producing delayed mid-inf…
Turbulent infall onto class 0 disks as cause of CAI brief condensation episode in the solar system
Jiachen Zheng, Xing Wei, Hongping Deng +2
Calcium-aluminum-rich inclusions (CAIs) in carbonaceous chondritic meteorites are the oldest relics in the solar system. Notably, their radiogenic age feature a brief (100 kyr) con…
Higher-Order Mean-Motion Resonances Can Form in Type-I Disk Migration
Finnegan Keller, Fei Dai, Wenrui Xu
Type-I disk migration can form a chain of planets engaged in first-order mean-motion resonances (MMRs) parked at the disk inner edge. However, while second- or even third-order res…
The 4-400 GHz Survey for the 32 Class II Disks in the Taurus Molecular Cloud
Chia-Ying Chung, An-Li Tsai, Melvyn Wright +4
We have compiled the 4-400 GHz broad spectra of 32 Class II protoplanetary disks in the Taurus-Auriga region, which represents the brightest one-third of sources detected in…
Grain Size in the Class I Protostellar System TMC-1A Constrained with ALMA and VLA Observations
Yusuke Aso, Satoshi Ohashi, Hauyu Baobab Liu +1
The disk mass and substructure in young stellar objects suggest that planet formation may start at the protostellar stage through the growth of dust grains. To accurately estimate…
SMA 200-400 GHz Survey for Dust Properties in the Icy Class II Disks in the Taurus Molecular Cloud
Chia-Ying Chung, Sean M. Andrews, Mark A. Gurwell +4
We present a new SMA survey of 47 Class II sources in the Taurus-Auriga region. Our observations made 12 independent samples of flux densities over the 200-400 GHz frequency range.…
