Abstract

One-hundred and three nearby bright Main-Sequence stars of spectral type F and G have been searched for infrared excess in order to find out ‘Vega-like’ characteristics. In our sample of bright Main-Sequence F and G stars none of the G-type stars show infrared excess but 4 out of 28 F-type stars are ‘Vega-like’ and the equilibrium distances of dust shells are within the planet-forming region.
