Secular evolution of compact binaries near massive black holes: gravitational wave sources and other exotica

, 2012
The environment near super massive black holes (SMBHs) in galactic nuclei contain a large number of stars and compact objects. A fraction of these are likely to be members of binaries.

Initial data for black hole-neutron star binaries: a flexible, high-accuracy spectral method [PDF]

, 2008
We present a new numerical scheme to solve the initial value problem for black hole-neutron star binaries. This method takes advantage of the flexibility and fast convergence of a multidomain spectral representation of the initial data to construct high ...

Search for Supermassive Black Hole Binaries in the Sloan Digital Sky Survey Spectroscopic Sample

, 2013
Supermassive black hole (SMBH) binaries are expected in a Lambda CDM cosmology given that most (if not all) massive galaxies contain a massive black hole at their center. So far, however, direct evidence for such binaries has been elusive.

Do binaries in clusters form in the same way as in the field? [PDF]

, 2009
We examine the dynamical destruction of binary systems in star clusters of different densities. We find that at high densities (10^4 - 10^5 Msun pc^-3) almost all binaries with separations > 10^3 AU are destroyed after a few crossing times.

The High Energy X-ray Probe (HEX-P): probing accretion onto stellar mass black holes

Frontiers in Astronomy and Space Sciences
Accretion is a universal astrophysical process that plays a key role in cosmic history, from the epoch of reionization to galaxy and stellar formation and evolution. Accreting stellar-mass black holes in X-ray binaries are one of the best laboratories to

A Connection between Submillimeter Continuum Flux and Separation in Young Binaries

, 1994
We have made sensitive 800-micron continuum observations of low-mass, pre-main sequence (PMS) binary stars with projected separations less than 25 AU in Taurus-Auriga to study disks in the young binary environment.

The evolution of photo-evaporating viscous discs in binaries [PDF]

, 2017
A large fraction of stars are in binary systems, yet the evolution of proto-planetary discs in binaries has been little explored from the theoretical side.

Binary Cumulants

Advances in Applied Mathematics, 2000
The author considers binary sequences (i.e. having letters from the set \(\{0,1\})\), and defines binary cumulants for joint probability distributions on binary sequences of finite length. Distributions on binary sequences of finite length are related to solve some fundamental mathematical problems (e.g. Hilbert's 17th problem).

Astronomical Data Resources for Binary and Multiple Stars

Open Astronomy, 2015
Binary stars form a significant part of stellar population. They are registered and observed by a number of methods. This is the reason for variety of present-day resources of astronomical data dealing with binaries and multiples.

Dusty Common Envelope Evolution

Galaxies
We present the first hydrodynamical simulations of common envelope evolution that include the formation of dust and the effect of radiation pressure on dust grains.
