Exact Mass Conservation in Binary Neutron Star Merger Simulations
Boris Daszuta, Sebastiano Bernuzzi, Joan Fontbuté +4
A long-standing problem in the simulation of neutron star spacetimes is the treatment of vacuum regions outside the stars. The use of an artificial low-density atmosphere is a comm…
Exploring Composition Mixing in Kilonova Ejecta with Ray-by-ray Simulations
Ruocheng Zhai, David Radice, Fabio Magistrelli +2
Binary neutron star merger (BNSM) ejecta are considered a primary repository of -process nucleosynthesis and a source of the observed heavy-element abundances. We implement comp…
Dynamical Instability of Multi-planet Systems and Free-floating Planets
Ruocheng Zhai, Man Hoi Lee, Tianjun Gan +1
The ejection of planets by the instability of planetary systems is a potential source of free-floating planets. We numerically simulate multi-planet systems to study the evolution…
Systematic KMTNet Planetary Anomaly Search. XII. Complete Sample of 2017 Subprime Field Planets
Yuqian Gui, Weicheng Zang, Ruocheng Zhai +39
We report the analysis of four unambiguous planets and one possible planet from the subprime fields () of the 2017 Korea Microlensing Telescope Network (KMT…
