Based on the undisturbed, finite thickness disk gravitational potential,we carried out 3-D Monte Carlo simulations of normal pulsars. We find that their scale h
We compare the contrast of faculae, in visible light and in the near infrared (NIR), that were associated with the active region NOAA 8518 which crossed the sol

The initial period of a pulsar is an important factor in our understandingof the formation of neutron stars and of the nature of the equation of state of neutro
