Numerical Modelling of Dusty Debris
نویسنده
چکیده
Infrared and submillimetre observations of nearby Vega-like stars have revealed a number of clumpy, asymmetric dust debris disks. Previous studies using semi-analytical and numerical methods have suggested planetary companions of various mass as the likely cause of most examples of disk asymmetry. In this paper, we modify an N-body symplectic gravitational integrator to include radiation terms and conduct medium-resolution parameter searches to identify likely planetary candidates in observed Vega-like systems. We also present high resolution models of Vega and ǫ Eridani, comparing our results to those of previous authors, and a new model for Fomalhaut.

Prospects for Detection of Catastrophic Collisions in Debris Disks
We investigate the prospects for detecting dust from two body collisions during the late stages of planet formation at 1–150 AU. We develop an analytic model to describe the formation of a dusty cloud of debris and use numerical coagulation and n-body calculations to predict observable signals from these events. In a minimum mass solar nebula, collisions of 100–1000 km objects at distances of 3...
متن کاملDetecting the Dusty Debris of Terrestrial Planet Formation
We use a multiannulus accretion code to investigate debris disks in the terrestrial zone, at 0.7–1.3 AU around a 1 M⊙ star. Terrestrial planet formation produces a bright dusty ring of debris with a lifetime of & 10 yr. The early phases of terrestrial planet formation are observable with current facilities; the late stages require more advanced instruments with adaptive optics. Subject headings...
متن کاملDusty Debris Disks as Signposts of Planets: Implications for Spitzer Space Telescope
Submillimeter and near-infrared images of cool dusty debris disks and rings suggest the existence of unseen planets. At dusty but nonimaged stars, semimajor axes of associated planets can be estimated from the dust temperature. For some young stars these semimajor axes are greater than 100 as seen from Earth. Such stars are excellent targets for sensitive near-infrared imaging searches for warm...
متن کاملDusty Debris Disks as Signposts of Planets: Implications for SIRTF
Submillimeter and near-infrared images of cool dusty debris disks and rings suggest the existence of unseen planets. At dusty but non-imaged stars, semi-major axes of associated planets can be estimated from the dust temperature. For some young stars these semi-major axes are greater than an arc second as seen from Earth. Such stars are excellent targets for sensitive near-infrared imaging sear...
متن کاملCharacterization of Dusty Debris Disks: the IRAS and Hipparcos Catalogs
Dusty debris disks around main sequence stars are signposts for the existence of planetesimals and exoplanets. From cross-correlating Hipparcos stars with the IRAS catalogs, we identify 153 stars within 120 pc of Earth that show excess emission at 60 μm. This search took special precautions to avoid false positives. Our sample is reasonably well distributed from late B to early K type stars, bu...
