Abstract

In the vicinity of the sun, studying of motions, velocities and features of local stars is a suitable way to cognition of dynamical features of galaxy stars, the source of galaxy disc and also the steps of star evolution. Using the results of big observatories and valid catalogs, many different researches has been done at this field. At present work, using the Hipparcos satellite data, a sample of stars in vicinity of the sun are studied and three parts of velocities of 493 stars which are located in 15 parsec from the sun such as transition velocity, radial velocity and their parallax are obtained. Also, local stars properties such as mass, their distribution in the galaxy, radius, temperature, galactic position and their relation with galactic velocities are investigated and finally the evolution of stars is predicted in the galaxy.
