Planet Migration in Protoplanetary Disks with Rims
Zhuoya Cao, Ya-Ping Li, Douglas N. C. Lin +1
Complex structures, including sharp edges, rings and gaps, have been commonly observed in protoplanetary disks with or without planetary candidates. Here we consider the possibilit…
Capture and Escape of Planetary Mean-motion Resonances in Turbulent Discs
Yi-Xian Chen, Yinhao Wu, Ya-Ping Li +4
Mean-motion resonances (MMRs) form through convergent disc migration of planet pairs, which may be disrupted by dynamical instabilities after protoplanetary disc (PPD) dispersal. T…
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…
Formation of free-floating planetary mass objects via circumstellar disk encounters
Zhihao Fu, Hongping Deng, Douglas N. C. Lin +1
The origin of planetary mass objects (PMOs) wandering in young star clusters remains enigmatic, especially when they come in pairs. They could represent the lowest-mass object form…
Concurrent Accretion and Migration of Giant Planets in their Natal Disks with Consistent Accretion Torque
Ya-Ping Li, Yi-Xian Chen, Douglas N. C. Lin
Migration commonly occurs during the epoch of planet formation. For emerging gas giant planets, it proceeds concurrently with their growth through the accretion of gas from their n…
Dust Accumulation near the Magnetospheric Truncation of Protoplanetary Discs. II. The Effects of Opacity and Thermal Evolution
Rixin Li, Yi-Xian Chen, Douglas N. C. Lin
Dust trapping in the global pressure bump induced by magnetospheric truncation offers a promising formation mechanism for close-in super-Earths/sub-Neptunes. These planets likely f…
Chaotic Type I Migration in Turbulent Discs
Yinhao Wu, Yi-Xian Chen, Douglas N. C. Lin
By performing global hydrodynamical simulations of accretion discs with driven turbulence models, we demonstrate that elevated levels of turbulence induce highly stochastic migrati…
Wide Dust Gaps in Protoplanetary Disks Induced by Eccentric Planets: A Mass-Eccentricity Degeneracy
Yi-Xian Chen, Zhuoxiao Wang, Ya-Ping Li +2
The tidal perturbation of embedded protoplanets on their natal disks has been widely attributed to be the cause of gap-ring structures in sub-mm images of protoplanetary disks arou…
Planet Population Synthesis
W. Benz, S. Ida, Y. Alibert +2
With the increasing number of exoplanets discovered, statistical properties of the population as a whole become unique constraints on planet formation models provided a link betwee…
