We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

Circumbinary disks are found in a variety of astrophysical scenarios, spanning binary star
formation to accreting supermassive black hole binaries. Depending on the characteristics of …

After the companion dynamically plunges through the primary's envelope, the two cores
remain surrounded by a common envelope and the decrease of the orbital period P orb …

Context. In this paper, we focus on post-asymptotic giant branch (post-AGB) binaries and
study the interaction between the different components of these complex systems. These …

We develop a rapid algorithm for the evolution of stable, circular, circumbinary discs suitable
for parameter estimation and population synthesis modelling. Our model includes disc mass …

Context. Many properties of circumbinary discs around evolved post-asymptotic giant branch
(post-AGB) binary systems are similar to those of protoplanetary discs around young stars …

Context. Most studies devoted to Herbig Ae/Be stars (HAeBes) assume solar metallicity.
However, the stellar metallicity,[M/H], is a fundamental parameter that can strongly differ …

Context. Stable circumbinary discs around evolved post-asymptotic giant branch (post-AGB)
binary systems composed of gas and dust show many similarities with protoplanetary discs …

Context. The features in the light curves and spectra of many Type I and Type II supernovae
(SNe) can be understood by assuming an interaction of the SN ejecta with circumstellar …

Aims. We aim to study the dust distribution in the central regions of the Keplerian disk of the
Red Rectangle, the prototype of binary post-AGB stars with rotating circumbinary disks, and …
