Radiation Hydrodynamics of Self-gravitating Protoplanetary Disks II. Accretion, Migration, Spin, and Internal Structure of GI Fragments

Yang Ni, Hongping Deng, Xue-Ning Bai

In the first paper of this series, we showed that gravitational instability (GI) in protoplanetary disks can produce fragments of planetary rather than brown-dwarf mass, leaving th…

A Formation-Stage Bottleneck for Exomoons around Close-in Rocky Planets

Rongxi Bi, Hongping Deng, Christian Reinhardt +2

Massive moons around rocky exoplanets are expected outcomes of giant impacts, yet no exomoon has been securely confirmed. We address this problem using meshless finite-mass simulat…

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…

Evidence for a Delayed UV Counterpart to X-ray Quasi-periodic Eruptions in Ansky

Hengxiao Guo, Zhen Yan, Ya-Ping Li +15

X-ray quasi-periodic eruptions (QPEs) represent a novel population of extreme, repeating nuclear transients whose physical origins remain debated. A defining characteristic of QPEs…

Effects of Stellar X-ray Photoevaporation on Planetesimal Formation via the Streaming Instability

Xuchu Ying, Beibei Liu, Haifeng Yang +7

The formation of planetesimals via the streaming instability (SI) is a crucial step in planet formation, yet its triggering conditions and efficiency are highly sensitive to both d…

Tidal disruption events in active galactic nuclei: on orbital inclination and Schwarzschild apsidal precession

Minghao Zhang, Wenda Zhang, Hongping Deng +2

Tidal disruption events (TDEs) in active galactic nuclei (AGNs) mark a regime where traditional vacuum models fail to capture the full dynamics, especially due to interaction betwe…
