Pulsarâ€™s Toggling Behavior: Research
Behavior of pulsar stars has been discovered to possess zombie like characteristics. They are stellar dead bodies which are left from massive star explosion. They are extremely magnetized materials that send beams into space.
Through the observations by astronomers, it has been discovered that eccentricity governs these neutron stars. It was seen that pulsar's X-ray emission switches on and off, just like the radio emission; except that it does it in reverse. This is in disagreement with the expected beliefs. Wim Hermsen (Netherlands Institute for Space Research and University of Amsterdam, the Netherlands) and his colleagues in their paper have also remarked that this whole phenomenon is a big mystery.
New interpretation said that the pulsar toggled between the X-ray pulses and highly organized pattern of radio pulses. To understand this, scientists examined a pulsar called PSR B0943+10. Xray changed their pattern at the same time as the radio waves. At places where radio signal is strong and organized, X-rays were weak. When the radio wave emission was weak, the X-rays became brighter.
Dr Ben Stappers from The University of Manchester's School of Physics and Astronomy said, "This was the opposite of what we had expected. I've likened the changes in the pulsar to a chameleon. Like the animal the star changes in reaction to its environment, such as a change in temperature."
