As more pulsars were discovered, the letter code became unwieldy, and so the convention then arose of using the letters PSR (Pulsating Source of Radio) followed by the pulsar's right ascension and degrees of declination (e.g. PSR 0531+21) and sometimes declination to a tenth of a degree (e.g. PSR 1913+16.7). Pulsars appearing very close ...
This is a delicate experiment, although millisecond pulsars are stable enough clocks that the time of arrival of the pulses can be predicted to the required accuracy; the experiments use collections of 20 to 50 pulsars to account for dispersion effects in the atmosphere and in the space between the observer and the pulsar. It is necessary to ...
A pulsar (pulsating star, on the model of quasar) [1] is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. [2] ...
An extremely slow pulsar has made scientists “slow down” their assumptions about other pulsars. The pace could be caused by a flashing magnetic field rather than pulsar rotation alone.
Millisecond pulsars have been detected in radio, X-ray, and gamma ray portions of the electromagnetic spectrum. The leading hypothesis for the origin of millisecond pulsars is that they are old, rapidly rotating neutron stars that have been spun up or "recycled" through accretion of matter from a companion star in a close binary system.
The pulsar is estimated to have a mass of 1.4 M ☉, which is typical for most neutron stars and pulsars. The radius is estimated to be around 10 kilometres or 6.2 miles (~1.5 × 10 −5 R ☉), also common for pulsars and neutron stars. The pulsar is extremely hot, with a surface temperature of up to around 28,856 K (28,583 °C; 51,481 °F).
There are no known examples of planets around young pulsars. [8] [9] "Third-generation" planets: [6] A companion star is destroyed through the interaction with a pulsar, forming a low-mass disk. Pulsars can emit energetic radiation that heats the companion star, until it overflows its Roche lobe and is eventually destroyed.
For non-sports fans, there's a more primal reason to watch: all the smoking hot players. ... Sure, but other professional athletes are rich and famous too, so it has to be more than that.
