When the primary star in a close binary system evolves into a giant and engulfs its
companion, its core and the companion temporarily orbit each other inside a common …

This work aims to present our current best physical understanding of common-envelope
evolution (CEE). We highlight areas of consensus and disagreement, and stress ideas …

In this work, we study the prospect of detecting the stochastic gravitational-wave background
with the TianQin Observatory. We consider sources of both astrophysical and cosmological …

We propose a new simple formalism to predict the orbital separations after common-
envelope phases with massive-star donors. We focus on the fact that massive red …

Double white dwarf (DWD) binaries are expected to be very common in the Milky Way, but
their intrinsic faintness challenges the detection of these systems. Currently, only a few tens …

Realistic models of the Galactic double white dwarf (DWD) population are crucial for testing
and quantitatively defining the science objectives of the Laser Interferometer Space Antenna …

The third data release of Gaia was the first to include orbital solutions assuming non-single
stars. Here, we apply the astrometric triage technique of Shahaf et al. to identify binary star …

With the remarkable success of the Ligo-Virgo-Kagra consortium in detecting binary black
hole mergers, it has become possible to use the population properties to constrain our …

We review the expected science performance of the New Gravitational-Wave Observatory
(NGO, aka eLISA), a mission under study by the European Space Agency for launch in the …

Post-common envelope binaries (PCEBs) containing a white dwarf (WD) and a main-
sequence (MS) star can constrain the physics of common envelope evolution and calibrate …
