Dust and Gas Debris Around Main Sequence Stars
Debris disks are dusty, gas-poor disks around main sequence stars (Backman & Paresce 1993; Lagrange, Backman & Artymowicz 2000; Zuckerman 2001). Micron-sized dust grains are inferred to exist in these systems from measurements of their thermal emission at infrared through millimeter wavelengths. The estimated lifetimes for circumstellar dust grains due to sublimation, radiation and corpuscular ...
متن کاملMid-infrared Spectra of Dust Debris around Main-sequence Stars
We report spectra obtained with the Spitzer Space Telescope in the λ = 14 – 35 μm range of 19 nearby main-sequence stars with infrared excesses. The six stars with strong dust emission show no recognizable spectral features, suggesting that the bulk of the emitting particles have diameters larger than 10 μm. If the observed dust results from collisional grinding of larger solids, we infer minim...
متن کاملExtrasolar Planets around Main Sequence Stars
The mass distribution of substellar companions exhibits a steep rise for masses below 5 MJ. Thus, the 14 companions having Msin i = 0.5 { 5 MJ are considered the best candidate planets around main sequence stars. The occurrence of such planets within 3 AU is 4%, but 2/3 of them orbit within just 0.3 AU. This \pile up" of planets near stars suggests that inward orbital migration occurred after f...
متن کاملDust disks around old Pre Main - Sequence stars : HST / NICMOS 2 scattered light images and modeling
We present recent near-infrared detections of circumstellar disks around the two old PMS Herbig stars HD141569 and HD100546 obtained with the HST/NICMOS2 camera. They reveal extended structures larger than 350–400 AU in radius. While the HD100546 disk appears as a continuous disk down to 40AU, the HD141569 environment seems more complex, splitted at least into two dust populations. As a convinc...
متن کاملSubmillimeter lines from circumstellar disks around pre-main sequence stars
Observations of submillimeter lines of CO, HCO, HCN and their isotopes from circumstellar disks around low mass pre-main sequence stars are presented. CO lines up to J=6→5, and HCO and HCN lines up to J=4→3, are detected from the disks around LkCa 15 and TW Hya. These lines originate from levels with higher excitation temperatures and critical densities than studied before. Combined with interf...
