The frequency of the pulsar changes since the the pulsar loses energy through magnetic dipole radiation.
Unlike the Global Positioning System of satellites used by cars and smart phones, the pulsar system wouldn't need humans to make daily corrections.
The Power3-II chip uses the same CMOS-7S copper process as the Pulsar chip, and is expected to run at 300MHz to 400MHz, providing from 50% to 100% more oomph than the current 200MHz Power3 chip.
The essential features of black widow and redback binaries are that they place a normal but very low-mass star in close proximity to a millisecond pulsar, which has disastrous consequences for the star," (http://www.
Ralph Eatough, scientist at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn and second author of the publication, said that there are different kinds of pulsars, just like there are different animal species in a zoo.
Millisecond pulsars are thought to achieve such speeds because they are gravitationally bound in binary systems with normal stars.
The idea of using pulsars to search for gravitational waves dates back to the late 1970s, Jenet says.
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight.
Many pulsars have a rather erratic behaviour: in the space of a few seconds, their emission becomes weaker or even disappears for a while, just to go back to the previous level after some hours," Hermsen said.
Similarly, by monitoring timing changes in a constellation of suitable millisecond pulsars spread all over the sky, we may be able to detect the cumulative background of passing gravitational waves.
In that theory, all pulsars emit both radio waves and gamma rays, The region where each type of radiation is generated is determined by the pulsar's strong magnetic field.
Pulsar SS400 shares similarities with the earlier rumoured Pulsar 375.
