Abstract
We have observed the star GSC 
to investigate whether it is
in a binary with PSR B1929+10. Its spectral type is K4-6 and its
luminosity class is III or II, therefore its distance is 2.4 kpc or
higher. Since the dispersion measure distance of PSR B1929+10 is 0.17 kpc,
we rule out the possibility that these two stars are associated
in a binary. This poses further constraints on the lower limit of kick
velocities in supernova explosions.
Key words: stars: individual: GSC 01060 / 01374 / stars: neutron / pulsars: individual: PSR B1929+10
Based on observations made with the William Herschel Telescope operated on the island of La Palma by the Isaac Newton Group in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias.
