Transitional millisecond pulsars provide us with a unique laboratory to study the interaction between the matter inflowing towards the NS, its rotating magnetosphere and the outgoing radiation, particle wind and jets.
A population of gamma-ray millisecond pulsars seen with the Fermi Large Area Telescope.
While young pulsars usually appear in isolation, more than half of millisecond pulsars occur in binary systems, which suggested an explanation for their rapid spin.
Researchers regard the system as a unique laboratory for understanding how millisecond pulsars form and for studying details of how accretion takes place on neutron stars.
These systems can completely consume their companion stars, and that's how we think solitary millisecond pulsars form", said Alice Harding, an astrophysicist at NASA's Goddard Space Flight Center said in a statement.
Their study can also help explain an increasing number of observed binary millisecond pulsars which seem to require a triple system origin.
Prof Lyne then considered the creation of binary pulsar systems and millisecond pulsars, objects rotating so rapidly that the pulse of radiation from the star occurs hundreds of times a second.
Because of their predictable pulsations-especially millisecond pulsars, which are the mission's prime target and are found to spin as much as 700 times per second-"they are extremely reliable celestial clocks" and can provide high-precision timing just like the atomic clock signals supplied through the 26-satellite, military-operated Global Positioning System (GPS), an Earth-centric service that weakens the farther one travels out beyond Earth orbit and into the solar system, Arzoumanian said.
To detect a general background of such waves, astronomers would need to monitor 20 of the millisecond pulsars for five to 10 years, with the arrival time of the radio waves determined to an accuracy of 100 nanoseconds, Jenet estimates.
There are some excess gamma rays observed in the Galactic Center but these are probably due to an unresolved population of millisecond pulsars.
17 ( ANI ): Two astronomers have proposed a new path for the formation of a newly discovered class of millisecond pulsars with similar orbital periods and eccentricities.
This star's capricious behavior appears to be fueled by a nearby companion star and may give new insights into the birth of millisecond pulsars.
