چکیده

The recently discovered RRAT sources are characterized by very bright radio bursts which, while being periodically related, occur infrequently. We find bursts with the same characteristics for the known pulsar B0656+14. These bursts represent pulses from the bright end of an extended smooth pulse-energy distribution and are shown to be unlike giant pulses, giant micropulses or the pulses of normal pulsars. The extreme peak-fluxes of the brightest of these pulses indicates that PSR B0656+14, were it not so near, could only have been discovered as an RRAT source. Longer observations of the RRATs may reveal that they, like PSR B0656+14, emit weaker emission in addition to the bursts.

Pulsar B 0656 + 14 a Very Nearby Rrat Source ?

The recently discovered RRAT sources are characterized by very bright radio bursts which, while being periodically related, occur infrequently. We find bursts with the same characteristics for the known pulsar B0656+14.

The extreme radio emission of PSR B 0656 + 14 — Is B 0656 + 14 a very nearby Rotating Radio Transient ?

We present a detailed study of the single radio pulses of PSR B0656+14. The emission can be characterized by two separate populations of pulses: bright pulses have a narrow " spiky " appearance in contrast to the underlying weaker broad pulses. The shape of the pulse profile requires an unusually long timescale to achieve stability (over 25,000 pulses at 327 MHz) caused by spiky emission. The e...

Pulsar Psr B0656+14, the Monogem Ring, and the Origin of the ‘knee’ in the Primary Cosmic Ray Spectrum

The Monogem ring is a bright, diffuse, 25◦-diameter supernova remnant easily visible in soft X-ray images of the sky. Projected within the ring is a young radio pulsar, PSR B0656+14. An association between the remnant and pulsar has been considered, but was seemingly ruled out by the direction and magnitude of the pulsar proper motion and by a distance estimate that placed the pulsar twice as f...

The bright spiky emission of pulsar B 0656 + 14

Context. We present a detailed study of the single radio pulses of PSR B0656+14, a pulsar also known to be a strong pulsed source of high-energy emission. Aims. Despite the extensive studies at high-energy wavelengths, there is little or no published work on its single-pulse behaviour in the radio band. In this report we rectify this omission. Methods. Radio observations using the Westerbork Sy...

We present the result of astrometric observations of the radio pulsar PSR B0656+14, made using the Very Long Baseline Array. The parallax of the pulsar is π = 3.47± 0.36 mas, yielding a distance 288 −27 pc. This independent distance estimate has been used to constrain existing models of thermal x-ray emission from the neutron star’s photosphere. Simple blackbody fits to the x-ray data formally ...
