Scientific paper

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 the present sample of bright main-sequence F and G stars, none of the G-type stars show infrared excess, but four out of 28 F-type stars are 'Vega-like', and the equilibrium distances of dust shells are within the planet-forming region.
