In 1968 (10 November), Lovelace and his collaborators discovered period \(P\approx 33\) ms of the Crab Pulsar.[1][2] As a graduate student working at Arecibo Observatory, Lovelace developed a version of the Fast Fourier transform program [3] [4] which was adapted to run on the Arecibo Observatory's CDC 3200 computer. [5] This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar. [6][7] A few weeks earlier, observers from the National Radio Astronomy Observatory reported about two pulsating sources near the Crab Nebula, with no evident periodicities.[8][9] Lovelace and collaborators found that one of pulsars (the NP 0532) is located in the center of the Crab Nebula (with precision of 10') and found it's period with a high precision: 33.09 ms.[6][7]
This was the fastest pulsar found at that time.[2][10] This discovery helped to proof the idea that pulsars were rotating neutron stars.[11][12] Before that, many scientists believed that pulsars were pulsating white dwarfs or neutron stars.[13][14]
