TESS Photometry and Radial Velocity Analysis of the sub-Neptune Exoplanet Ï Mensae c and the Wider Ï Mensae Planetary System
Skylar S. Larsen, Jake D. Turner, Nikole K. Lewis +10
The paper combines six years of TESS photometry with 22 years of radial‑velocity data to refine the orbital parameters and masses of the sub‑Neptune π Men c and its companion plane…
Bridging Roche Lobe Overflow and micro-TDEs: The Runaway Evolution of Eccentric Mass Transfer in Star-Black Hole Binaries
Tian-Shun Chen, Dong Lai
Binary systems may undergo mass transfer while maintaining significant orbital eccentricities. Stellar-mass black holes (sBHs) can strip stars on eccentric orbits and produce micro…
Magnetically Driven Retrograde Precession in Misaligned Black Hole Accretion Flows
Hong-Xuan Jiang, Yosuke Mizuno, Dong Lai +2
Observations of accreting black hole (BH) systems, such as microquasars and supermassive black holes, often reveal a precessing jet with changing directions, indicating a misaligne…
Spin and Obliquity Distributions of Low-mass Planets Shaped by Dynamical Instability
Dieran Wang, Jiaru Li, Dong Lai
Exoplanetary systems hosting multiple low-mass planets are thought to have experienced dynamical instability, during which planet-planet collisions and mergers occur; these collisi…
Binary Stars Approaching Supermassive Black Holes: Hydrodynamics of Stellar Collisions, Mass Fallback and Partial TDEs
Fangyuan Yu, Dong Lai
When binaries are injected into low-angular-momentum orbits around a central supermassive black hole (SMBH), various outcomes can occur, including binary tidal breakup, double stel…
Binary Stars Approaching Supermassive Black Holes: Tidal Break-up, Double Stellar Disruptions and Stellar Collision
Fangyuan Yu, Dong Lai
In galactic centers, stars and binaries can be injected into low-angular-momentum orbits, resulting in close encounters with the central supermassive black hole (SMBH). Previous wo…
