Tracking Protostellar Variability in Massive Protoclusters with ALMA: I. Insights from QUARKS and MaMMOtH
Yuhan Yang, Tie Liu, Sheng-Yuan Liu +22
Millimeter/submillimeter variability is often attributed to dynamical disk-mediated accretion, yet detection is limited to low-mass protostars in nearby clouds. Recent observations…

K-band High-Resolution Spectroscopy of Embedded Massive Protostars
Tien-Hao Hsieh, Michihiro Takami, Michael S. Connelley +7
A classical paradox in high-mass star formation is that powerful radiation pressure can halt accretion, preventing further growth of a central star. Disk accretion has been propose…
The Mass Ratio Distribution of Tertiary Induced Binary Black Hole Mergers
Yubo Su, Bin Liu, Dong Lai
Many proposed scenarios for black hole (BH) mergers involve a tertiary companion that induces von Zeipel-Lidov-Kozai (ZLK) eccentricity cycles in the inner binary. An attractive fe…
On the Correlation between Hot Jupiters and Stellar Clustering: High-eccentricity Migration Induced by Stellar Flybys
Laetitia Rodet, Yubo Su, Dong Lai
A recent observational study suggests that the occurrence of hot Jupiters (HJs) around solar-type stars is correlated with stellar clustering. We study a new scenario for HJ format…
ALMA View of the Infalling Envelope around a Massive Protostar in S255IR SMA1
Sheng-Yuan Liu, Yu-Nung Su, Igor Zinchenko +4
The massive young stellar object S255IR NIRS3 embedded in the star forming core SMA1 has been recently observed with a luminosity burst, which is conjectured as a disc-mediated var…
Spin-Orbit Misalignments in Tertiary-Induced Black-Hole Binary Mergers: Theoretical Analysis
Yubo Su, Dong Lai, Bin Liu
Black-hole (BH) binary mergers driven by gravitational perturbations of tertiary companions constitute an important class of dynamical formation channels for compact binaries detec…
Dynamics of Colombo's Top: Generating Exoplanet Obliquities from Planet-Disk Interactions
Yubo Su, Dong Lai
Large planetary spin-orbit misalignments (obliquities) may strongly influence atmospheric circulation and tidal heating in the planet. A promising avenue to generate obliquities is…
Physics of Tidal Dissipation in Early-Type Stars and White Dwarfs: Hydrodynamical Simulations of Internal Gravity Wave Breaking in Stellar Envelopes
Yubo Su, Daniel Lecoanet, Dong Lai
In binaries composed of either early-type stars or white dwarfs, the dominant tidal process involves the excitation of internal gravity waves (IGWs), which propagate towards the st…
