Hydrodynamical Simulations of Resonant Breaking in Multi-Planet Systems via Rebound Migration During Disk Dispersal
Beibei Liu, Clément Baruteau, Zhaohuan Zhu +3
This study extends the investigation of rebound outward migration to multi-planet systems near an inner expanding disk cavity driven by stellar X-ray photoevaporation. Using 2D hyd…
Coupling dynamical accretion and chemical differentiation: A unified framework for the diversity of Earth and Mars
Zhihui Kong, Beibei Liu, J. ZhangZhou +8
The physical and geochemical differences between Earth and Mars provide fundamental constraints on terrestrial planet formation, yet a self-consistent framework linking dynamical a…
Capture and Stability of Resonant Planet Pairs in Turbulent Disk
Linghong Lin, Beibei Liu, Fei Dai +6
We present a theoretical framework for the resonance capture and stability of two-planet systems in turbulent disks. By incorporating stochastic forcing (parameterized by ) alo…
Reproducing the stellar-mass dependence of the giant planet occurrence rate with pebble accretion models
Heather F Johnston, Olja Panic, Sabine Reffert +2
The stellar mass dependence of the unbiased giant planet occurrence rate may be the best statistical tool to constrain the formation of such planets. This rate rises and falls as a…
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…
Hydrodynamical Simulations of Planet Rebound Migration in Photo-evaporating Disks
Beibei Liu, Clément Baruteau, Zhaohuan Zhu +2
This study investigates the orbital migration of a planet located near the truncated edge of protoplanetary disks, induced by X-ray photo-evaporation originating from the central s…
