Exploring the Environment of a Young Circumstellar Disk System
نویسنده
چکیده
I discuss the spectral energy distribution (SED) of the star PDS 144C, in regards to whether it is a member of the PDS 144 system. Looking at the data, I come to the conclusion that it is not a member of the system. Additionally, I perform point spread function (PSF) subtraction on the southern member of the system, PDS 144S, in an attempt to better resolve the disk and determine basic disk properties.

The Evolution of Circumstellar Disks: Lessons from the VLT and ISO
There is strong evidence that the planets in the solar system evolved from a disk-shaped solar nebula ≈4.56 Gyr ago. By studying young stars in various evolutionary stages, one aims at tracing back the early history of the solar system, in particular the timescales for disk dissipation and for the formation of planetary systems. We used the VLT & ISAAC, and ESA’s Infrared Space Observatory & IS...
متن کاملThe Circumstellar Environment of the TTS SU Aurigae
In this contribution we investigate how a disk determines the physical and geometrical properties of the circumstellar environment of the T Tauri SU Aurigae. Our model of the spectral energy distribution of this star includes the central young star, a flat black disk and a diffuse envelope. We also describe the inner interaction region between the disk and the star, the magnetosphere, by analys...
متن کاملThe Circumstellar Environments of Young Stars at AU Scales
We review recent advances in our understanding of the innermost regions of the circumstellar environment around young stars, made possible by the technique of long baseline interferometry at infrared wavelengths. Near-infrared observations directly probe the location of the hottest dust. The characteristic sizes found are much larger than previously thought, and strongly correlate with the lumi...
متن کاملHigh-resolution Optical and Near-infrared Imaging of Young Circumstellar Disks
In the past five years, observations at optical and near-infrared wavelengths obtained with the Hubble Space Telescope and ground-based adaptive optics have provided the first well-resolved images of young circumstellar disks which may form planetary systems. We review these two observational techniques and highlight their results by presenting prototype examples of disks imaged in the Taurus-A...
متن کاملStructure and Evolution of Circumstellar Disks Around Young Stars: New Views from ISO
A question central to understanding the origin of our solar system is: how do planets form in circumstellar disks around young stars? Because of the complex nature of the physical processes involved, multi–wavelength observations of large samples will be required in order to obtain a complete answer to this question. Surveys undertaken with ISO have helped to solve pieces of this puzzle in addi...
