The evolution of a primordial binary black hole due to interaction with cold dark matter and the formation rate of gravitational wave events
Sergey Pilipenko, Maxim Tkachev, Pavel Ivanov
In this Paper we consider a problem of formation and evolution of orbital parameters of a binary primordial black hole (PBH) due to gravitational interaction with clustering cold d…
Nonlinear tidal excitation of super-harmonic gravity waves in main-sequence stars in binary and exoplanetary systems
P. B. Ivanov, S. V. Chernov, A. J. Barker
We study the role of nonlinear effects on tidally-excited internal gravity waves in stellar radiation zones in exoplanetary or binary systems. We are partly motivated to study tide…
The dynamics of twisted disc formed after the tidal disruption of a star by a rotating black hole
P. B. Ivanov, V. V. Zhuravlev, J. C. B. Papaloizou
We consider misaligned accretion discs formed after tidal disruption events occurring when a star encounters a supermassive rotating black hole. We use the linear theory of warped…
Dynamical tides in exoplanetary systems containing Hot Jupiters: confronting theory and observations
S. V. Chernov, P. B. Ivanov, J. C. B. Papaloizou
We study the effect of dynamical tides associated with the excitation of gravity waves in an interior radiative region of the central star on orbital evolution in observed systems…
On the formation of a quasi-stationary twisted disc after a tidal disruption event
M. Xiang-Gruess, P. B. Ivanov, J. C. B. Papaloizou
We investigate misaligned accretion discs formed after tidal disruption events that occur when a star encounters a supermassive black hole. We employ the linear theory of warped ac…
The evolution of a supermassive retrograde binary embedded in an accretion disk
P. B. Ivanov, J. C. B. Papaloizou, S. -J. Paardekooper +1
In this note we discuss the main results of a study of a massive binary with unequal mass ratio, q, embedded in an accretion disk, with its orbital rotation being opposed to that o…
