Observations of Circumstellar Disks

2007
IRAS observations first showed that a sizable fraction of the nearby stars are (still) surrounded by dust disks (Cheng et al. [3]), the most prominent prototypes of this class of dusty stars being Vega, β Pic, and α PsA. Such dust or debris disks have generated particular interest in the framework of young earth-like planetary systems.

Ripping up a circumstellar disk

Science, 2020
Stellar Astrophysics During the process of star formation, a disk of gas and dust forms around the young star, controlling the accretion of more material. Once the star has formed, any leftover material in this circumstellar disk can form planets. If a binary or triple star forms at the center of the disk, theoretical models predict that tidal torques ...

Circumstellar disks and planetary formation

The Moon and the Planets, 1978
The role of circumstellar disks in star and planetary formation is briefly reviewed. The observed disk around MWC 349 is used as an example and a table of evolutionary time scales and parameters is presented. The disk about MWC 349 is characteristic of that expected about a massive star. Disk structure about solar mass stars is more completely reviewed

Observations of circumstellar disks and infall

AIP Conference Proceedings, 1997
This paper presents an overview of the current status of millimeter and submillimeter wavelength observations of circumstellar disk and infall associated with young stars. Particular attention is paid to the progress and promise of high resolution interferometer observations.

Physical processes in circumstellar disks

1996
We review the basic physical processes which occur incircumstellar disks. We discuss the possible role of gravitational instabilities in producing both disk accretion and secondary bodies within the disk. Next, we consider the viscous evolution of disks and the possible sources of the viscosity. We briefly consider magnetic instabilities tidal effects,
