Resonant Super-Earths Dancing With EKL Oscillations: TTV Phase Excitation and Resonance Disruption by EKL Interactions between a Cold Jupiter and Stellar Companion
Pin-Gao Gu, Gongjie Li
Near-resonant Kepler planets are dynamically hot, as evidenced by nonzero transit timing variation (TTV) phases, indicating that free eccentricities are not damped. Recent observat…

Investigating the influence of the radiative torque disruption on the size evolution of dust in the heliosphere
Chi-Hang Ng, Pin-Gao Gu, Thiem Hoang
In this paper, we conduct a detailed study on the effect of Radiative Torque Disruption (RATD) mechanism on the fragmentation of micrometer-sized dust grains into nanoparticles wit…

ALMA Observations of Proper Motions of the Dust Clumps in the Protoplanetary Disk MWC 758
I-Hsuan Genevieve Kuo, Hsi-Wei Yen, Pin-Gao Gu
To study the dust dynamics in the dust trapping vortices in the protoplanetary disk around MWC~758, we analyzed the 1.3 mm continuum images of the MWC~758 disk obtained with the At…
