Pulsar

did not get recognized for their hard work and discovery. You might not be familiar with Jocelyn Bell Burnell, Esther Lederberg, and Chien-Shiung Wu. These are women who helped with advancements in science. Jocelyn Bell Burnell is a scientist who discovered pulsars. She made the discovery in 1967 while a graduate at Cambridge University as a radio astronomer. She started working with Anthony Hewish and her job was to assist in…

I found four Perytons when I searched for non-repetitive, dispersed radio bursts in the archival Parkes Multibeam Pulsar Survey. The motivation was to understand this population better, including “Rotating Radio Transients” (RRATs), “Fast Radio Bursts” (FRBs) and “Perytons”. RRATs are radio pulsars which can be detected in single-pulse searches more easily than periodicity searches. It is now believed that these are extreme examples of the radio pulsar population, and their pulsed emissions are…

Pulsars: Lighthouses of the universe Imagine a star between four and eight times the mass of our sun exploding into a supernova. Next imagine watching the inner core condense into a sphere due to the enormous gravity of the star like there’s a new star forming in its place. This new star is so dense it smashes electrons and protons together forming neutrons which form a neutron star. This is the recipe for a pulsar. There are several types of neutron stars but this essay will highlight pulsars.…

tell you where these forms of radiation come from. The answer: Pulsars. Pulsars, or neutron stars, are physics sandboxes that provide extreme conditions for humans to experiment with which are not readily available on Earth. Due to this usefulness, the discovery and research of these phenomena should be of the utmost importance. These neutron stars, barely 12 miles across, are troves of undiscovered scientific mysteries. To begin our journey into the mysteries of pulsars, it is wise to start at…

Throughout the history, numerous scientist made scientist made notable contributions to scientific field which led to significant changes. Those who did amassed their fame and fortune through recognition of their findings while some were denied of their findings. Jocelyn Bell Burnell who then a 24 year old student made a significant impact on findings of pulsars and found the pulsars, a discovery that solved mystery of life and answered unclear questions of astronomy, did not receive the…

Bajaj Eliminator, the internal Bajaj team concurrently developed the 150cc and 180cc Pulsar. BAL also had technical collaborations with Kubota Corporation, Japan for diesel engines & Tokyo R&D Co. Ltd, Japan for production of two-wheelers. Investments in Research & Development: Eliminator launched in Jan 2001 proved too expensive for the Indian Market & thus failed to make a mark. BAL recognized an opportunity provided by changing demographics that suggested a market for a more powerful yet…

cloud. When the core collapses, it heats up which forms clumps that forms protostars. This process takes about 10 million years and will create a star one day. When a star is near the end of it’s life, it can undergo gravitational collapse where protons and electrons are scrunched together. This is what is known as a neutron star. The materials in a neutron star are packed in very tightly. One cubed sized amount of this material can weigh as much as Mount Everest! There have been theories about…

White dwarfs are small and hot, mostly made of carbon. After a red giant loses its outer layers, this is what’s left. They are about the size of Earth, but a lot heavier. A brown dwarf has too small of a mass to have nuclear fusion. A neutron star is very small and super-dense star that is composed mostly of tightly-packed neutrons. It has a thin atmosphere of hydrogen. A pulsar is a rapidly spinning neutron star that emits energy in pulses. A star with eventually use up most of its hydrogen,…

gravity on a planet depends on its size and its mass. If life were to be found on a super earth the legs of said organisms would be thicker to compensate for the atmosphere. It would also be much harder for these organisms to break their atmosphere and reach space due to the fact that everything would be much heavier in this atmosphere. 4.0 How are exoplanets discovered, and how do spectroscopic analyses determine a “fingerprint” of life? Exoplanets have been discovered in a series of…

discovered the second pulsar to ever be observed, SR 1913 + 16. A pulsar is a cosmic source of regular and rapid pulses of radiation usually at radio frequencieS.7 This pulsar was different than the first because it was a binary pulsar meaning it was not a singular body but two revolving around each other. The two bodies were separated by a distance a few times that from the earth to the moon.8 This newly found binary pulsar created much excitement because it provided scientists with a…
