Rotating radio transient

A Rotating radio transient ( dt rapidly rotating volatile radio source ) is a pulsar, a rotating neutron star with a magnetic dipole directed along its synchrotron radiation, which can be better found by searching for single pulses as in a Fourier analysis. The distance between individual pulses is between 10 and detectable 10,000 seconds, wherein the rotation period of RRATs is between 0.1 and seven seconds.

Properties

The Rotating radio transient have been first described in 2005 as a Transient radio bursts. This was the result of a specific search for individual bursts in the radio emission rather than how to search for pulsars previously usual with the help of exact temporal repetitive signals. The width of each radio pulses is between two and 30 milliseconds. The RRAT period show jumps as normal pulsars. In the radio range, the pulses when switched on, strongly modulated with no evidence of modulation frequency.

In the field of X-ray radiation thermal radiation could be detected by at least one RRAT and the derived temperature of more than a million degrees Kelvin confirmed nature as neutron stars. The point source is surrounded by an extended halo in X-rays, resulting from a pulsar wind nebula, or by scattering. There are at least two regular pulsars, which would temporarily perceived as rotating radio transients. Probably the RRATs are only an extreme form of Nullings and the Giant pulses in normal pulsars. This hypothesis leads the current numbers of known rotating radio Transients in an increase in the formation rate of neutron stars by a factor of five to six. This means that either the number of core-collapse supernova in the Milky Way has been underestimated by a corresponding factor, or even run it more development channels to the formation of pulsars. Alternatively, could lead to the suspension of the pulses changes in the number of free charge carriers or current density in the magnetosphere.
