Formation of high eccentric GW inspirals and tidal captures in binary-single interactions.

Abstract: Interactions between binaries and singles in dense stellar systems play an important role both dynamically and observationally. A key question is how dissipative effects, such as gravitational wave emission and and tidal interactions, might affect the dynamics and outcomes of these interactions. I will in this talk show that the main effect from including such corrections is the formation of GW inspirals and tidal captures. These inspirals or captures are formed with an extremely high eccentricity which leads to distinct observables. I will in particular show recent theoretical progress, which makes it possible to estimate inspiral cross sections for any mass hierarchy and orbital configuration. This is currently impossible using brute-force N-body techniques.
