Disc Fragmentation. III. The need for a new paradigm for formation of planets within close binary systems
Luyao Zhang, Sergei Nayakshin, Clement Baruteau +2
The paper proposes that planets in tight binary systems form concurrently with the binary stars via gravitational fragmentation of massive circumstellar discs, with early‑forming m…
Disc fragmentation. II. Ejection of low mass Free Floating Planets from growing binary systems
Sergei Nayakshin, Luyao Zhang, Aleksandra ÄaloviÄ +4
Observations indicate that disc fragmentation due to Gravitational Instability (GI) is the likely origin of massive companions to stars, such as giant planets orbiting M-dwarf star…
Search for Past Stellar Encounters and the Origin of 3I/ATLAS
Yiyang Guo, Luyao Zhang, Fabo Feng +3
3I/ATLAS, the third discovered interstellar object, has a heliocentric speed of 58 km/s and exhibits cometary activity. To constrain the origin of 3I/ATLAS and its past dynamical e…
A Cartesian catalog of 30 million Gaia sources based on second-order and Monte Carlo error propagation
Luyao Zhang, Fabo Feng, Yicheng Rui +2
Accurate measurements of stellar positions and velocities are crucial for studying galactic and stellar dynamics. We aim to create a Cartesian catalog from Gaia DR3 to serve as a h…
