Pulsar puzzle stumps astronomers.
Scientist are surprised again, however surprises are one of the greatest motives to become a scientist. A surprise generally means we are going to learn something new. Very often something we could never have imagined. When the phrase ‘I would never have believed it until I saw it with my own eyes’ Literally applies.
An odd fast-spinning pulsar, which is locked in an elongated orbit around another star much like our Sun has left astronomers puzzled how such a system could have formed. |
Typical pulsars spin once a second to about 10 or 20 times a second but J1903+0327 is a “millisecond pulsar” and spins much faster. |
| spins 465 times a second and is the fifth fastest-spinning pulsar known in our Galaxy, say Champion and colleagues, who found the star using the Arecibo radio telescope in Puerto Rico |
| it has a very elongated orbit around a star similar in size and composition to our Sun |
“What we have found is a millisecond pulsar that is in the wrong kind of orbit around what appears to be the wrong kind of star,” says Champion. “Now we have to figure out how this strange system was produced.” |
