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…
Eccentric Accretion Disks in Active Galactic Nuclei
Hongping Deng
We report that moderately eccentric flows around supermassive black holes (SMBHs), formed via either circumnuclear gas accretion or tidal disruption events, generate eccentricity c…
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…
The stochastic nature of migration of disc instability protoplanets in three-dimensional hydrodynamical and MHD simulations of fragmenting discs
Noah Kubli, Lucio Mayer, Hongping Deng +1
We present a detailed analysis of the nature of migration of protoplanetary clumps formed via disc instability in self-consistent 3D hydrodynamical (HD) and magneto-hydrodynamical…
