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…

Microlensing Events in Five Years of Photometry from the Zwicky Transient Facility

Ruocheng Zhai, Antonio C. Rodriguez, Shude Mao +5

Microlensing has a unique advantage for detecting dark objects in the Milky Way, such as free-floating planets, neutron stars, and stellar-mass black holes. Most microlensing surve…
