... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

. I will briefly summarise the methods to estimate the magnetic field strengths of different types of neutron stars and the caveats associated with them. In this context I will present some recent results we have obtained in finding the limits to the field strengths of accreting millisecond X-ray pulsars from the interaction between the accretion disk and neutron star magnetosphere.
