Bajaj achieved this with the 150cc and 180cc Pulsar. This system consists of a pulsar and neutron star in orbit around one another. Bajaj released the UG 4.5 versions of the Pulsar 150. Bajaj also introduced a new Light Sports version of Pulsar named as Pulsar 135LS. An example is a Jupiter-mass object orbiting the pulsar PSR J1719-1438. In 2006, Bajaj introduced another version of Pulsar (UG III). The Sentra was now based on the N16 Pulsar or Nissan Bluebird Sylphy. It featured a 140 kilowatt turbocharged MR16DDT engine found in the Nissan Pulsar ST-S variant. The Philippines also used the Sentra name for its version of the Pulsar. Japanese market N15 Pulsar and Lucino models had drivers airbag as standard. In addition, it can easily detect planets which are relatively far away from the pulsar. Some have considered rotational energy from the central pulsar. They used observations of the pulsar PSR J0537-6910. It was this work that led to the discovery of the first binary pulsar.
