Resumen

The distance from the sun to the center ofthe Galaxy R0 remains a fundamental parameter forGalactic structure. This study uses 36,061 A and Fstars of all luminosity classes with position, parallax,and proper motion taken from the Hipparcos catalogand radial velocities from the Wilson and StrasbourgData Center catalogs. The nonlinear kinematical equationsof condition are solved by the Nelder-Mead simplexalgorithm and give R0 =7.68±0.07 kpc. Therandomness of the residuals, calculated by a runs testas 91.9% probable, shows that the kinematical modelyields satisfactory results.
