The gas dissipation from a protoplanetary disk is one of the key processes affecting planet formation, and it is widely accepted that it happens on timescales of a few million years for disks around single stars. In recent years, several protoplanetary disks have been discovered in multiple-star systems, and despite the complex environment in which they find themselves, some of them seem to be quite old, a situation that may favor planet formation. A clear example of this is the disk around HD…

Circumbinary Disk Evolution in the Presence of an Outer Companion Star
We consider a hierarchical triple system consisting of an inner eccentric binary with an outer companion. A highly misaligned circumbinary disk around the inner binary is subject to two competing

The Role of Multiplicity in Disk Evolution and Planet Formation
The past decade has seen a revolution in our understanding of protoplanetary disk evolution and planet formation in single-star systems. However, the majority of solar-type stars form in binary
Long-lived Protoplanetary Disks in Multiple Systems: The VLA View of HD 98800
The conditions and evolution of protoplanetary disks in multiple systems can be considerably different from those around single stars, which may have important consequences for planet formation. We
Observational constraints on dust disk sizes in tidally truncated protoplanetary disks in multiple systems in the Taurus region
The impact of stellar multiplicity on the evolution of planet-forming disks is still the subject of debate. Here we present and analyze disk structures around ten multiple stellar systems that were
A triple protostar system formed via fragmentation of a gravitationally unstable disk
TLDR
Observations of dust and molecular gas emission reveal a disk with a spiral structure surrounding the three protostars in the triple protostar system L1448 IRS3B that appears susceptible to disk fragmentation at radii between 150 and 320 astronomical units, consistent with models for a protostellar disk that has recently undergone gravitational instability, spawning one or two companion stars.
Gas flow and accretion via spiral streamers and circumstellar disks in a young binary protostar
TLDR
High–angular resolution observations of the circumbinary disk around [BHB2007] 11, a young binary protostar system, observe accretion and radio jets associated with the protobinary system, consistent with theoretical predictions.
A circumbinary protoplanetary disk in a polar configuration
Nearly all young stars are initially surrounded by ‘protoplanetary’ disks of gas and dust, and in the case of single stars at least 30% of these disks go on to form planets1. The process of
SHORT DISSIPATION TIMES OF PROTO-PLANETARY DISKS: AN ARTIFACT OF SELECTION EFFECTS?
The frequency of disks around young stars, a key parameter for understanding planet formation, is most readily determined in young stellar clusters where many relatively coeval stars are located in
The dispersal of protoplanetary disks around binary stars
TLDR
It is found that photoevaporative clearing leaves a signature on the distribution of circumbinary disklifetimes, with a sharp increase in disk lifetimes for binary separations a<~0.3-1AU.

We combine the results from several multiplicity surveys of pre-main-sequence stars located in four nearby star-forming regions with Spitzer data from three different Legacy Projects. This allows us

Binary systems are very common among field stars, yet the vast majority of known exoplanets have been detected around single stars. While this relatively small number of planets in binaries is
