In 1967, a young doctor. Student Jocelyn Bell discovered an object that “shimmered” in the radio wavelength. This “flicker”, appearing as a regular train of radio pulses, would later be identified with the radiation emitted by a neutron star. A decade later, an artist used a "stacked plot" image of a large number of successive radio pulses as a label and it ended up becoming an iconic image in popular culture. The image was originally created by Harold Craft for his Ph.D. thesis at the Arecibo Observatory, using data from the pulsar discovered by Jocelyn Bell.

ABOUT THE CONFERENCE
Twinkle, little star. In August 1967, Jocelyn Bell, a young student at Cambridge University, discovered something that sparkled on the radio wavelength. It turned out that it really was a “little star”! It soon appeared that she had made one of the greatest discoveries in astronomy; she had discovered a neutron star. Since then, nearly three thousand neutron stars have been discovered. In this talk, I will explain how a neutron star produces electromagnetic radiation and why it “pulsates”.

ABOUT THE LECTURE SERIES
This lecture series is organized by the Astronomical Society of India as part of its golden jubilee celebrations. Aimed at undergraduate and graduate students, this lecture series led by renowned astrophysicist and teacher Professor G. Srinivasan starts from the first principles of physics and rigorously expands the subject to the current state of our understanding.
