J/AZh/88/954        Geometry of radio pulsar magnetospheres  (Malov+, 2011)

The geometry of radio pulsar magnetospheres. Malov I.F., Nikitina E.B. <Astron. Zh. 88, 954 (2011)> =2011AZh....88..954M =2011ARep...55..878M
ADC_Keywords: Pulsars ; Radio sources ; Morphology Abstract: Data on the profiles and polarization of the 10- and 20-cm emission of radio pulsars are used to calculate the angle β between the rotational axis of the neutron star and its magnetic moment. It is shown that, for these calculations, it is sufficient to use catalog values of the pulse width at the 10% level W10, since the broadening of the observed pulses due to the transition to the full width W0 and narrowing of the pulses associated with the emission of radiation along tangents to the field lines approximately cancel each other out. The angles β1 are calculated for 283 pulsars at 20cm and 132 pulsars at 10cm, assuming that the line of sight passes through the center of the emission cone. File Summary:
