Azad Bin Rajib Hazarika MIAMP AES is an Indian mathematician, astrophysicist and plasma physicist who spent his professional life in India.
Hazarika studied higher secondary at Poona College and the graduation (BSc), postgraduation (MSc), Doctorate PhD mathematics) from Jai Narain Vyas University.
Hazarika was JRF UGC - NET, Senior research fellowship UGC - NET, post-doctoral fellow. He worked as Research Associate DST in Plasma Physics Division in the project Development of Plasma Physics division in Institute of Advanced Study in Science and Technology where he taught and did research. His teaching and research career comes a long time: (1993-) Kamla Nehru College for Women, Jodhpur and the science faculty of Jai Narain Vyas University. At different other institutions: Institute of Advanced Study in Science and Technology (1998–1999), Nowgong College (2000–2001) working as assistant professor in the mathematics department, as a gazetted officer I of Assam Education Service (AES - I), Government of Assam in Diphu Government College (2004–present). His name appears in Marquis Who's Who in the world and WorldCat.[1]
Known for theoretical studies of the physical processes of importance to the structure and evolution of the neutron stars. His mathematical treatment of stellar evolution yielded many of the current theoretical models of the later evolutionary stages of massive stars and black holes. The Chandrasekhar limit is improved for neutron stars as Bhatia Hazarika Limit is named after him. Hazarika worked on a wide variety of physical solutions to the understanding of stellar structure, neutron star, stellar dynamics, the quantum theory of hydrodynamic and plasma instability, turbulence, equilibrium and the stability of mathematical theory of black holes and the theories of colliding gravitational waves and gravitational collapse.[2] At the Institute of Advanced Study in Science and Technology, he developed a theoretical model explaining the structure of neutron stars that took into account the mass with the velocities of electrons that comprise their degenerate matter. He showed that the mass of a neutron star could not exceed 2.828 times that of the sun against the Chandrasekhar limit. Hazarika revised the models of stellar dynamics on rotating neutron stars or pulsars about the galactic centre. His solution to this complex dynamical problem involved a set of many partial differential equations, describing a new quantity as
M star = 2 3/2 Msun
Hazarika has received many awards from different organisations:
