Session 111 - Pulsars.
Display session, Saturday, January 10
Exhibit Hall,
Recent observations have been used to construct multiwavelength (radio to gamma ray) light curves and energy spectra for 10 spin-powered pulsars. The preponderance of light curves showing two peaks connected by a bridge of emission suggests radiation coming from above one pole of the neutron star. In all cases, the peak luminosity is seen in the X-ray or gamma-ray energy range. Although thermal emission is seen in a number of middle-aged pulsars, the output is dominated by nonthermal emission. The integrated luminosity is found to be roughly proportional to the polar cap current or the open field line voltage.
