Circumstellar Disks Around Binary Stars In Taurus
We have conducted a survey of 17 wide (> 100 AU) young binary systems in Taurus with the Atacama Large Millimeter Array (ALMA) at two wavelengths. The observations were designed to measure the masses of circumstellar disks in these systems as an aid to understanding the role of multiplicity in star and planet formation. The ALMA observations had sufficient resolution to localize emission within...
متن کاملVortices in Circumstellar Disks
We discuss the physics of vortices in the circumstellar disks associated with young stellar objects. We elucidate the basic physical properties of these localized storm systems. In particular, we consider point vortices, linear vortices, the eeects of self-gravity, magnetic elds, and nonlinear aspects of the problem. We nd that these vortices can exist in many diierent forms in the disks of you...
متن کاملOn the alignment between the circumstellar disks and orbital planes of Herbig Ae/Be binary systems
Context. The majority of the intermediate mass, pre-main-sequence Herbig Ae/Be stars reside in binary systems. As these systems are young, their properties may contain an imprint of the star formation process at intermediate masses (2-15 M⊙). However, these systems are generally spatially unresolved, making it difficult to probe their circumstellar environment to search for manifestations of th...
متن کاملObservations of Circumstellar Disks
The imaging of disks around young stars presents extreme challenges in high dynamic range, angular resolution, and sensitivity. Recent instrumental advances have met these challenges admirably, leading to a marked increase in imaging discoveries. These have opened up a new era in studies of the origin of planetary systems. Questions about our own solar system’s formation, and of the prevalence ...
متن کاملImaging Circumstellar Debris Disks
In the early 1980s, the Infrared Astronomy Satellite (IRAS) detected thermal emission from dust grains with temperatures of 50-125 K and fractional luminosities (Lgrains/L∗) in the range 10 -10 around four main sequence stars: Vega, Fomalhaut, β Pictoris, and ǫ Eridani. Coronagraphic observations of β Pic confirmed that the grains do indeed lie in a disk, perhaps associated with a young planeta...
