Observations 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 کاملObservations of circumstellar disks with infrared interferometry
The structure and composition of circumstellar disks around young stars is one of the areas in which infrared interferometry has had a major impact. I will review the observational progress in this field starting from the earliest observations of T Tauri, Herbig Ae/Be and FU Ori objects with smaller interferometers. Highlights of recent work include measurements of the inner disk size across 5 ...

متن کاملModelling of Infrared/millimetre Images of Circumstellar Disks with an Embedded Planet
We present radiative transfer (RT) simulations for a circum-stellar disk around a solar-type star with an embedded planet of 1 Jupiter mass. The three-dimensional density structure in the disk results from hydrodynamical simulations. For the simulation of the RT, we applied a self-consistent three-dimensional continuum RT code. Based on images and visibility curves derived from the calculations...
متن کاملDynamics of Circumstellar Disks
We present a series of 2-dimensional hydrodynamic simulations of massive disks around protostars. We simulate the same physical problem using both a ‘Piecewise Parabolic Method’ (PPM) code and a ‘Smoothed Particle Hydrodynamic’ (SPH) code, and analyze their differences. The disks studied here range in mass from 0.05M∗ to 1.0M∗ and in initial minimum Toomre Q value from 1.1 to 3.0. We adopt simp...
