Cosmic rays from Galactic pulsars
We calculate energy spectra and mass composition of cosmic rays accelerated by the galactic population of pulsars during their radio and gamma-ray phase. It is assumed that a significant part of the pulsar rotational energy is lost on acceleration of iron nuclei extracted from the surface of the neutron star. The nuclei are accelerated, at first when passing the outer gap of the inner pulsar ma...
متن کاملPopulation Synthesis of Pulsars: Magnetic Field Effects
New results based on methods of population synthesis, concerning magnetic field effects on the evolution of pulsars are reported. The present study confirms that models with timescales for the magnetic field decay longer than the pulsar lifetime are in better agreement with data. These new simulations indicate that the diagram log(PṖ ) log(ts) alone cannot be used to test field decay models. Th...
متن کاملEffect of magnetic field on electron neutrino sphere in pulsars
We study the neutrino interaction rates through charged as well as neutral current weak interactions in hot, dense magnetized matter. At densities near the neutrino sphere, matter in the presence of intense magnetic field is polarized and electrons and protons typically occupy the lowest Landau level. The weak interaction rates in such a situation are severally modified leading to a sizable cha...
متن کاملTitle On the bimodal magnetic field distribution of binary pulsars
We combine the idea of movement of magnetic flux tubes in the stellar interiors with the analysis of crustal physics of accreting neutron stars in lowand high-mass X-ray binaries to explain the bimodal magnetic field distribution of binary pulsars. We propose that this distribution may result from different crustal properties of neutron stars with different accretion rates and amounts of accret...
متن کاملSlowly rotating pulsars and magnetic field decay
Twodozen long period pulsars are separated from the swarm of ordinary pulsars by an obvious gap in the P versus Sd diagram (where Sd = log Ṗ + 21.0), with a plausible upper boundary for ordinary pulsars. Possible pulsar evolutionary tracks are discussed to explain the diagram in terms of previously suggested scenarios of magnetic field decay. The (P–Sd) diagram is difficult to understand if the...
