Atomic gas in debris discs
We have conducted a search for optical circumstellar absorption lines in the spectra of 16 debris disc host stars. None of the stars in our sample showed signs of emission line activity in either Hα, Ca II or Na I, confirming their more evolved nature. Four stars were found to exhibit narrow absorption features near the cores of the photospheric Ca II and Na I D lines (when Na I D data were ava...
متن کاملVertical structure of debris discs
Context. The vertical thickness of debris discs is often used as a measure of these systems’ dynamical excitation, and as clues to the presence of hidden massive perturbers such as planetary embryos. However, this argument might be flawed because the observed dust should be naturally placed on inclined orbits by the combined effect of radiation pressure and mutual collisions. Aims. We criticall...
متن کاملCollisional Dust Avalanches in Debris Discs
We quantitatively investigate how collisional avalanches may develop in debris discs, as the result of the initial break-up of a planetesimal or comet-like object, triggering a collisional chain reaction due to outward escaping small dust grains. We use a specifically developed numerical code that follows both the spatial distribution of the dust grains and the evolution of their size-frequency...
متن کاملDebris discs around nearby Solar analogues
An unbiased search for debris discs around nearby Sun-like stars is reported. Thirteen G-dwarfs at 12-15 parsecs distance were searched at 850 μm wavelength, and a disc is confirmed around HD 30495. The estimated dust mass is 0.008 M⊕ with a net limit . 0.0025 M⊕ for the average disc of the other stars. The results suggest there is not a large missed population of substantial cold discs around ...
متن کاملA search for debris discs around stars with giant planets
Eight nearby stars with known giant planets have been searched for thermal emission in the submillimetre arising from dust debris. The null results imply quantities of dust typically less than 0.02 Earth masses per star. Conversely, literature data for 20 Sun-like stars with debris discs show that 5 per cent have gas giants inside a few astronomical units – but the dust distribution suggests th...
