Binaries are softer than they seem: Effects of an external potential on the scattering dynamics of binaries

Yonadav Barry Ginat, Hagai B. Perets

Binary evolution is influenced by dynamical scattering with other stars in dense environments. Heggie's law states that, due to their environments, hard binaries (whose orbital ene…

The Equivalence Principle and The Cosmological Constant Problem

Yonadav Barry Ginat

In this essay I point out that, in the context of semi-classical gravity, the equivalence principle can mitigate the cosmological constant problem. On a Minkowski space-time backgr…

Probing supermassive stars and massive black hole seeds through gravitational wave inspirals

Yael Raveh, Yonadav Barry Ginat, Hagai B. Perets +1

We propose a novel source of gravitational wave emission: the inspirals of compact fragments inside primordial supermassive stars (SMSs). Such systems are thought to be an essentia…

An Analytical, Statistical Approximate Solution for Dissipative and non-Dissipative Binary-Single Stellar Encounters

Yonadav Barry Ginat, Hagai B. Perets

We present a statistical approximate solution of the bound, non-hierarchical three-body problem, and extend it to a general analysis of encounters between hard binary systems and s…

Multiple-Scales Approach to The Averaging Problem in Cosmology

Yonadav Barry Ginat

The Universe is homogeneous and isotropic on large scales, so on those scales it is usually modelled as a Friedmann-Lemaître-Robertson-Walker (FLRW) space-time. The non-linearity o…

Axion oscillations in binary systems: angle-action surgery

Vincent Desjacques, Evgeni Grishin, Yonadav Barry Ginat

Scalar, tensor waves induce oscillatory perturbations in Keplerian systems that can be probed with measurements of pulsar timing residuals. In this paper, we consider the imprint o…
