A survey of ultra-compact high-state AM CVn binaries with ZTF and Gaia: New discoveries and observational constraints on Galactic space density

Ilkham Galiullin, Antonio C. Rodriguez, Kareem El-Badry +9

Ultra-compact AM CVn binaries in the high-state of stable mass transfer () are expected to be among the loudest persistent sources for upcomin…

Lithium as a Signpost for Compact Object Binary Candidates in the LAMOST Medium Resolution Survey

Yang Shen, Joshua D. Simon, Kareem El-Badry +1

Binary systems with black hole or neutron star companions are often associated with lithium enhancement. Gaia NS1, a recently discovered neutron-star binary with a lithium-enhanced…

Searching for the Third Wheel: High-Contrast Imaging Constraints on Tertiaries to Black Hole and Neutron Star Binaries

Pranav Nagarajan, Kareem El-Badry, Aniket Sanghi

The authors performed deep adaptive‑optics near‑infrared imaging of several black‑hole and neutron‑star binaries to look for tertiary companions, finding no convincing detections a…

Population demographics of post-interaction WDMS binaries: From common envelope evolution to stable mass transfer

Natsuko Yamaguchi, Kareem El-Badry, Cheyanne Shariat

The authors jointly model three observational samples of white‑dwarf + main‑sequence binaries to constrain how mass transfer and common‑envelope phases shape their demographics, fi…

A systematic survey for hypervelocity runaways from thermonuclear supernovae

Kareem El-Badry, Klaus Werner, Ken J. Shen +16

The explosion of a white dwarf (WD) in a close binary can launch a surviving runaway star at velocities of . Such runaways provide a direct probe of…

The Contribution of Disrupted Dense Star Clusters to Gaia's Compact Object Binaries

Aryanna Schiebelbein-Zwack, Claire S. Ye, Marta Reina-Campos +3

We present the first model of the Milky Way's detectable compact object--luminous star binary population from disrupted dense star clusters. We bridge large-scale cosmological star…
