Observational data from nine pulsars, including the Crab pulsar, these stars suggest that fast-spinning neutron emit electromagnetic equivalent of a sonic boom, and a model created to understand this phenomenon shows that the source of emissions would be traveling faster than light. The researchers say that when the bias currents of these emissions are released with a mechanism similar to a synchrotron sources could travel to six times the speed of light, or 1.8 million miles per second. However, while the radiation source exceeds the speed of light, the emitted radiation travels at the normal speed of light once it leaves the source. "This is not science fiction, and does not violate any laws of physics in this model," said John Singleton of Los Alamos National Laboratory in a press conference at the meeting of the Americn Astronomical Society in Washington, DC. "And do not violate Special Relativity Theory of Einstein."
This model, known as pulsars supralumínicos model was described by Singleton and his colleague Andrea Schmidt as the solution to many issues unresolved pulsars. "We take into account a number of chances in this model," said Singleton, "and a huge amount of observational data available, so check there are many opportunities."
Pulsars emit short bursts of radio waves surprisingly regular. The emission of pulses, polarization circulating currents move in a circular orbit, and radiation is analogous to electronic facilities used to produce synchrotron radiation from the far infrared to X-ray experiments in biology and other issues. In other words, the pulsar is a source of radiation with a very wide band width.
However, Singleton said, the fact that the source is moving faster than the speed of light results in a flow that varies as a function of frequency. "Despite the high rate of self-bias current, small movements of the charged particles that form indicating that their rates are still below that of light," he said.
supralumínicas These bias currents are disturbances in the plasma of the pulsar's atmosphere in which oppositely charged particles are minimally displaced in opposite directions, are induced by the rotating magnetic field of the neutron star. This creates the electromagnetic equivalent of a sonic boom from supersonic aircraft speeds. Just foma that can be heard perfectly the "outbreak" very far from the ship, the pulsar analog signals remain strong over long distances.
Already in the 1980 Nobel Prize winner Vitaly Ginzburg and colleagues demonstrated that such bias currents faster than light would act as sources of electromagnetic radiation. Since then, the theory has been developed by Houshang Ardavan, University of Cambridge in the UK, and several demonstrations on the ground of this principle have been carried out in the United Kingdom, Russia and the United States. So far, it has been shown that the bias currents that travel at six times the speed of light emitting highly targeted bursts of radiation in experiments on earth.
Although the presentation of Singleton and Schmidt was very technical, as was recognized over much of the audience (and the audience on-line), LANL researchers said supralumínico model fits the data of the Crab pulsar and eight other pulsars, extending the electromagnetic frequencies from radio to X-rays. In each case, supralumínico model took into account the entire set of data over 16 orders of magnitude of frequency basically only two adjustable parameters. In contrast to previous attempts, which have used several disparate models to fit the small frequency ranges of the spectra of the pulsar, Schmidt said that only a flotation may take into account the entire spectrum of the pulsar.
"We believe we can explain all observational data using this method," said Singleton.
When asked, Singleton said he received some hostile reactions to his model within the community of pulsars, but many others had been "disinterest ready because it explains many of their data."
