Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

The Binary Population and Spectral Synthesis suite of binary stellar evolution models and
synthetic stellar populations provides a framework for the physically motivated analysis of …

Context. Many stars do not live alone, but instead have one or more stellar companions.
Observations show that these binaries, triples, and higher-order multiples are common …

Abstract Using the Zwicky Transient Facility alert stream, we are conducting a large
spectroscopic campaign to construct a complete, volume-limited sample of transients …

Gravitational wave transients, resulting from the merger of two stellar remnants, are now
detectable. The properties and rates of these directly relates to the stellar population which …

In recent years, observations have shown that multiple-star systems such as hierarchical
triple and quadruple-star systems are common, especially among massive stars. They are …

The gamma-ray burst GRB 211211A and its associated kilonova-like emission were
reported recently. A significant difference between this association event and GRB …

The Galactic center is dominated by the gravity of a super-massive black hole (SMBH),
Sagittarius A*, and is suspected to contain a sizable population of binary stars. Such …

We present panchromatic observations and modeling of the Calcium-rich supernova (SN)
2019ehk in the star-forming galaxy M100 (d≈ 16.2 Mpc) starting 10 hr after explosion and …

We conduct the first 3D hydrodynamic simulations of oxygen–neon white dwarf–neutron
star/black hole mergers (ONe WD–NS/BH mergers). Such mergers constitute a significant …
