Follow-up observations of β-pic-like stars

Session I: Main Sequence Disks


Following the discovery, by IRAS, of the dust disc around Vega and three other main sequence stars, searches have been made for other candidates. Theβ-Pic-like candidates have 12µm excesses and 100µm fluxes (unlike the Vega-like candidates), so they can be further investigated using ground-based techniques. Data are presented here, comprising 10µm spectroscopy and sub-mm observations, for several candidates from the Walker & Wolstencroft list, showing that the stars have silicate dust, and optically thick dust discs even at 1300µm.
