After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

Abstract Michigan InfraRed Combiner-eXeter (MIRC-X) is a new highly sensitive six-
telescope interferometric imager installed at the CHARA Array that provides an angular …

Context. Post-asymptotic giant branch (post-AGB) binaries are surrounded by massive disks
of gas and dust that are similar to the protoplanetary disks that are known to surround young …

Binary post-asymptotic giant branch (post-AGB) stars are thought to be the products of a
strong but poorly understood interaction during the AGB phase. The aim of this contribution …

Context. The innermost astronomical unit (au) in protoplanetary disks is a key region for
stellar and planet formation, as exoplanet searches have shown a large occurrence of close …

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 …

It is often assumed that gravitational-wave (GW) events resulting from the merger of stellar-
mass black holes are unlikely to produce electromagnetic (EM) counterparts. We point out …

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. Aims. In order to study the effects of rotating disks in the post-asymptotic giant
branch (post-AGB) evolution, we observe a class of binary post-AGB stars that seem to be …

Many disc-type post-asymptotic giant branch (post-AGB) stars are chemically peculiar,
showing underabundances of refractory elements in their photospheres that correlate with …
