  • The interferometric observations of dwarf stars in the solar neighbourhood, combined with Hipparcos parallaxes provide very precise values of their linear diameters. In this paper, we report the direct measurement of the angular diameter of the bright star Sirius A with the VINCI/VLTI instrument. We obtain a uniform disk angular diameter ofUD= 5:9360:016 mas in the K band and a limb darkened value ofLD = 6:039 0:019 mas. In combination with the Hipparcos parallax of 379:221:58 mas, this… CONTINUE READING
