The statistical properties of circumstellar disks around young stars are important for constraining theoretical models for the formation and early evolution of planetary systems. In this brief review, I survey the literature related to ground‐based and Spitzer‐based infrared (IR) studies of young stellar clusters, with particular emphasis on tracing the evolution of primordial (“protoplanetary”) disks through spectroscopic and photometric diagnostics. The available data demonstrate that the… Expand

A METHOD TO CONSTRAIN THE SIZE OF THE PROTOSOLAR NEBULA
Observations indicate that the gaseous circumstellar disks around young stars vary significantly in size, ranging from tens to thousands of AU. Models of planet formation depend critically upon theExpand
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 inExpand
Giant planet migration, disk evolution, and the origin of transitional disks
We present models of giant planet migration in evolving protoplanetary disks. Our disks evolve subject to viscous transport of angular momentum and photoevaporation, while planets undergo Type IIExpand
A RESOLVED DEBRIS DISK AROUND THE CANDIDATE PLANET-HOSTING STAR HD 95086
Recently, a new planet candidate was discovered on direct images around the young (10–17 Myr) A-type star HD 95086. The strong infrared excess of the system indicates that, similar to HR8799, β Pic,Expand
Planet population synthesis driven by pebble accretion in cluster environments
The evolution of protoplanetary discs embedded in stellar clusters depends on the age and the stellar density in which they are embedded. Stellar clusters of young age and high stellar surfaceExpand
Protoplanetary disks and planet formation around brown dwarfs and very low-mass stars
Brown dwarfs and very low-mass stars are very common in the Galaxy, yet we know little about the planetary systems they may host. Here we review observational evidence emerging from comparativeExpand
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 binaryExpand
From birth to death of protoplanetary discs: modelling their formation, evolution and dispersal
Formation, evolution, and dispersal processes of protoplanetary disks are investigated and the disk lifetime is estimated. Gravitational collapse of a pre-stellar core forms both a central star and aExpand
Super-Earth masses sculpted by pebble isolation around stars of different masses
We develop a pebble-driven model to study the formation and evolution of planets around stars in the mass range of 0.08 and 1 solar mass. The growth and migration of a large number of individualExpand
Evolution of gas and dust in circumstellar environments: from protoplanetary discs to the formation of planets
Understanding the evolution of gas and dust in circumstellar discs is a major topic in present day astronomy, linked to one of the most interesting challenges: understanding the formation of planets.Expand
