Inferred timescales for common envelope ejection using wide astrometric companions
Andrei P. Igoshev, Hagai B. Perets, Erez Michaely
Evolution of close binaries often proceeds through the common envelope stage. The physics of the envelope ejection (CEE) is not yet understood, and several mechanisms were suggeste…

Axion resonances in binary pulsar systems
Mor Rozner, Evgeni Grishin, Yonadav Barry Ginat +2
We investigate the extent to which resonances between an oscillating background of ultra-light axion and a binary Keplerian system can affect the motion of the latter. These resona…

Wide binary companions to massive stars and their use in constraining natal kicks
Andrei P. Igoshev, Hagai B. Perets
The origin of ultra-wide massive binaries (orbital separations ~AU) and their properties are not well characterized nor understood. Here we use the second Gaia d…
