Strange Pulsar: Newly Discovered Spinning Star Baffles Astronomers

Scientists have discovered a puzzling spinning star that is spontaneously switching between two very different personalities, flipping between emitting strong X-rays and emitting intense radio waves.

While radio frequencies are known to vary as the star changes personalities, the newfound star is the first time example of variability in X-rays as well. The star, called a pulsar because it appears to pulse, has astronomers perplexed.

"When we look now to what is so far published in papers, nothing at this moment can explain what is happening," said the study's lead author, Wim Hermsen of the Netherlands Institute for Space Research and the University of Amsterdam.

The newfound pulsar is officially known as PSR B0943+10. The 5 million-year-old spinning star whips through a rotation every 1.1 seconds which is considered pretty slow for a star of its type, researchers said.

1. Like a variable Klystron or Magnetron

With a variable Magnetic Field, or it could change wavelength by varying the size of the resonant cavity (volume of the Star.) Perhaps the Star is expanding and contracting over time,

2. Or it could be a new sub-type of pulsar
