Eccentric Signatures of Stellar-Mass Binary Black Holes with Circumbinary Disks in LISA
Isobel M. Romero-Shaw, Samir Goorachurn, Magdalena Siwek +1
Stellar-mass binary black holes may have circumbinary disks if formed through common-envelope evolution or within gaseous environments. Disks can drive binaries into wider and more…
