Scientists observe structure within the pulses of a Millisecond Pulsar

Indian astronomers have detected microstructure emissions from a millisecond pulsar for the first time. Millisecond pulsars (MSP) are highly magnetized, rapidly rotating neutron stars that take as little as one-thousandth to one-hundredth of a second to rotate about its axis once. In a recently published study, scientists from the Department of Physics at the Indian Institute of Science (IISc) and the National Centre for Radio Astrophysics (NCRA), Tata Institute for Fundamental Research (TIFR), have discovered these microstructure emissions using the Giant Metrewave Radio Telescope (GMRT), an array of thirty antennae scanning the sky for radio sources. They are now uncovering the processes that produce these microstructure emissions. While similar emissions had been discovered from more slowly rotating pulsars, this is the first time they have been discovered coming from millisecond pulsars.
