full_context: Document 1: Indian Journal of Physics: The Indian Journal of Physics is a monthly peer-reviewed scientific journal published by Springer Science+Business Media on behalf of the Indian Association for the Cultivation of Science. It was established in 1926 by C. V. Raman and covers applied, experimental, and theoretical physics. The editor-in-chief is Subham Majumdar.
Document 2: Ashoke Sen: Ashoke Sen, FRS ( ; Bengali: অশোক সেন ; born 1956) is an Indian theoretical physicist and distinguished professor at the Harish-Chandra Research Institute, Allahabad. He also is the Morningstar Visiting professor at MIT and a distinguished professor at the Korea Institute for Advanced Study. His main area of work is String Theory. He was among the first recipients of the Fundamental Physics Prize “for opening the path to the realisation that all string theories are different limits of the same underlying theory”. Of the prizes for theoretical physics, the Fundamental Physics Prize is the one which pays the most prize money.
Document 3: Chandrasekhar number: The Chandrasekhar number is a dimensionless quantity used in magnetic convection to represent ratio of the Lorentz force to the viscosity. It is named after the Indian astrophysicist Subrahmanyan Chandrasekhar.
Document 4: Subrahmanyan Chandrasekhar: Subrahmanyan Chandrasekhar, FRS (Tamil: சுப்பிரமணியன் சந்திரசேகர் ; ; 19 October 1910 – 21 August 1995), was an Indian American astrophysicist who was awarded the 1983 Nobel Prize for Physics with William A. Fowler "for his theoretical studies of the physical processes of importance to the structure and evolution of the stars". His mathematical treatment of stellar evolution yielded many of the best current theoretical models of the later evolutionary stages of massive stars and black holes. The Chandrasekhar limit is named after him.
Document 5: Chandrasekhar equation: In astrophysics, the Chandrasekhar equation is a dimensionless form of the Poisson equation for the density distribution of a spherically symmetric isothermal gas sphere subjected to its own gravitaional force, named after the Indian American astrophysicist Subrahmanyan Chandrasekhar. The equation reads
Document 6: Chandrasekhar potential energy tensor: In astrophysics, Chandrasekhar potential energy tensor provides the gravitational potential of a body due to its own gravity created by the distribution of matter across the body, named after the Indian American astrophysicist Subrahmanyan Chandrasekhar. The Chandrasekhar tensor is a generalization of potential energy in other words, the trace of the Chandrasekhar tensor provides the potential energy of the body.
Document 7: Chandrasekhar limit: The Chandrasekhar limit ( ) is the maximum mass of a stable white dwarf star. The limit was first indicated in papers published by Wilhelm Anderson and E. C. Stoner, and was named after Subrahmanyan Chandrasekhar, the Indian astrophysicist who independently discovered and improved upon the accuracy of the calculation in 1930, at the age of 19, in India. This limit was initially ignored by the community of scientists because such a limit would logically require the existence of black holes, which were considered a scientific impossibility at the time. White dwarfs resist gravitational collapse primarily through electron degeneracy pressure. (By comparison, main sequence stars resist collapse through thermal pressure.) The Chandrasekhar limit is the mass above which electron degeneracy pressure in the star's core is insufficient to balance the star's own gravitational self-attraction. Consequently, white dwarfs with masses greater than the limit would be subject to further gravitational collapse, evolving into a different type of stellar remnant, such as a neutron star or black hole. (However, white dwarfs generally avoid this fate by exploding before they undergo collapse.) Those with masses under the limit remain stable as white dwarfs.
Document 8: Meghnad Saha: Meghnad Saha FRS (6 October 1893 – 16 February 1956) was an Indian astrophysicist best known for his development of the Saha ionization equation, used to describe chemical and physical conditions in stars. Saha was the first scientist to relate a star's spectrum to its temperature, developing thermal ionization equations that have been foundational in the fields of astrophysics and astrochemistry. He was repeatedly and unsuccessfully nominated for the Nobel Prize in Physics. Saha was also politically active and was elected in 1952 to India's parliament.
Document 9: Chandrasekhar family: The Chandrasekhar family is an Indian intellectual family. Several members of the family have achieved scientific distinction, notably in the field of physics. Two members of the family, Sir C. V. Raman and his nephew, Subrahmanyan Chandrasekhar, were Nobel laureates in physics.
Document 10: Schönberg–Chandrasekhar limit: In stellar astrophysics, the Schönberg–Chandrasekhar limit is the maximum mass of a non-fusing, isothermal core that can support an enclosing envelope. It is expressed as the ratio of the core mass to the total mass of the core and envelope. Estimates of the limit depend on the models used and the assumed chemical compositions of the core and envelope; typical values given are from 0.10 to 0.15 (10% to 15% of the total stellar mass). This is the maximum to which a helium-filled core can grow, and if this limit is exceeded, as can only happen in massive stars, the core collapses, releasing energy that causes the outer layers of the star to expand to become a red giant. It is named after the astrophysicists Subrahmanyan Chandrasekhar and Mario Schönberg, who estimated its value in a 1942 paper.
Document 11: Raman Science Centre: The Raman Science Centre and Raman Planetarium Complex at Nagpur is an interactive science centre affiliated with Mumbai's Nehru Science Centre. The centre was developed to promote a scientific attitude, portray the growth of science and technology and their applications in industry and human welfare, and hold science exhibits. The centre is named after famous Nobel Prize winner Indian physicist Chandrasekhara Venkata Raman.
Document 12: Subramanian Anantha Ramakrishna: Subramanian Anantha Ramakrishna (born 30 November 1972) is a Professor of Physics in Indian Institute of Technology Kanpur specializing in optics and condensed matter physics. He was awarded the Shanti Swarup Bhatnagar Prize for Science and Technology, India's highest prize for excellence in science, mathematics and technology, in the physical sciences category in the year 2016. Ramakrishna obtained M.Sc. degree from Indian Institute of Technology Kanpur in 1995 after pursuing the integrated 5-year M.Sc. programme and secured Ph.D. from Raman Research Institute, Bangalore, in 2001 for a thesis titled "Light transport and localization in Active and passive random media" written under the supervision of Prof. N. Kumar. He spent two years in Imperial College, London, as a Post Doctoral researcher and joined Indian Institute of Technology Kanpur as an Assistant Professor in May 2003 where he now holds the position of Professor.
Document 13: Raman Research Institute: Raman Research Institute (RRI) is an institute of scientific research located in Bangalore, India. It was founded by Nobel laureate C. V. Raman. Although it began as an institute privately owned by Sir C. V. Raman, it is now funded by the government of India.
Document 14: Collapsar: Collapsar is the shortened form to describe a collapsed star. When an old star no longer has enough fuel for significant fusion reactions there can be three possible outcomes depending on the star's mass. If the star’s mass is less than 1.4 solar masses, known as the Chandrasekhar limit, it will stabilize and shrink, becoming a white dwarf. Above the said limit the star will either become a neutron star or a black hole.
Document 15: C. V. Raman: Sir Chandrasekhara Venkata Raman (7 November 188821 November 1970) was an Indian physicist born in the former Madras Province in India presently called as Tamil Nadu, who carried out ground-breaking work in the field of light scattering, which earned him the 1930 Nobel Prize for Physics. He discovered that when light traverses a transparent material, some of the deflected light changes wavelength. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. In 1954, India honoured him with its highest civilian award, the Bharat Ratna.
