Extractions: Died : 1995 Subrahmanyan Chandrasekhar, a Nobel Laureate in Physics and one of the greatest astrophysicists of modern times was born on October 19, 1910 in Lahore, (now in Pakistan) to parents Chandrasekhara Subrahmanya Ayyaa civil servant and Sita Balakrishnan. Being the nephew of the great, C.V. Raman a Nobel Prize winner in Physics young Chandrashekhar's interest in the subject came naturally to him. In 1930, at the age of 19, he completed his degree in Physics from Presidency College, Madras and went to England for postgraduate studies at the Cambridge University. Chandrasekhar was noted for his work in the field of stellar evolution, and in the early 1930s he was the first to theorize that a collapsing massive star would become an object so dense that not even light could escape it; now known as the Black hole. He demonstrated that there is an upper limit ( known as 'Chandrasekhar Limit' ) to the mass of a White dwarf star. His theory challenged the common scientific notion of the 1930s that all stars, after burning up their fuel, became faint, planet-sized remnants known as white dwarfs. But today, the extremely dense neutron stars and black holes implied by Chandrasekhars early work are a central part of the field of astrophysics. Initially his theory was rejected by peers and professional journals in England. The distinguished astronomer Sir Arthur Eddington publicly ridiculed his suggestion that stars could collapse into such objects( black holes). Disappointed, and reluctant to engage in public debate, Chandrasekhar moved to America and in 1937 joined the faculty as an Assistant Professor of Astrophysics at the University of Chicago and remained there till his death. At Chicago, he immersed himself in a personalized style of research and teaching, tackling first one field of astrophysics and then another in great depth. He wrote more than half a dozen definitive books describing the results of his investigations. More than 100,000 copies of his highly technical books have been sold. He also served as editor of the Astrophysical Journal, the fields leading journal, for nearly 20 years; presided over a thousand colloquia; and supervised Ph.D. research for more than 50 students.

Some will be young astronomers just starting to study science, others will be famous scientists who lived long ago. The featured astronomer for March, 2003 is Subramanyan Chandrasekhar was born in India in 1910. He went to high school and college in Madras, India and went to graduate school in England. Photo from The Man Behind the Name Chandra X-Ray Observatory Besides studying the life and death of stars, Chandra also wrote many books about stars, light and black holes. Chandra received the Nobel Prize in 1985, which is the biggest prize that a scientist can get. He died in 1993 in Chicago, where he had lived and taught since 1937! Today, many scientists who study stars and light use what Chandra discovered. Astronomers honored him for his discoveries and teaching by naming an X-Ray Telescope after him: The Chandra X-Ray Observatory . This satellite observes the X-Ray radiation coming from galaxies, black holes, supernovae and other things. Subramanyan Chandrasekhar made many discoveries in astronomy, but he also taught many scientists. According to Nobel laureate Hans Bethe, "Chandra was a first-rate astrophysicist and a beautiful and warm human being." "Chandra probably thought longer and deeper about our universe than anyone since Einstein," said Martin Rees, Great Britain's Astronomer Royal. (

Extractions: The Stellar Graveyard Observations may have confirmed the extreme compactness of white dwarfs, but their internal constitution was not easy to understand given the knowledge of physics that was available in the mid 1920s. In fact, the structure of such compact stars seemed like an unavoidable paradox, and its resolution is a landmark in the development of our understanding of the internal structure of stars. The electron gas in matter as dense as in the companion of Sirius must be degenerate and should be described by quantum statistics. Basically, even an absolutely cold assembly of electrons must retain a spread of momenta (due to Pauli's exclusion principle), and if the electrons are confined to a finite volume (as in a star) there will be an associated pressure. It is this ``electron degeneracy'' pressure that balances gravity in white dwarfs. So, what has this got to do with black holes and neutron stars? Well, a closer examination shows that the electrons in a massive dwarf will be moving at velocities near the speed of light. This means that any theoretical study of white dwarfs must include relativistic corrections. This turns out to have a surprising astrophysical implication. In July 1930 the then 19 year old Subramanyan Chandrasekhar, partly during the long sea voyage from India to England (where he was to become a student at Cambridge), made a calculation that predicted that white dwarfs can never be more massive than roughly 1.4 solar masses. This remarkable result implies that a massive star will not simply fade away as it runs out of nuclear fuel. Instead it will collapse under its own gravitational pull. This leads to a supernova explosion and the subsequent formation of either a neutron star or a black hole.

Extractions: Che cosa è il limite di Chandrasekhar? Risponde Paolo Sirtoli Il limite di Chandrasekhar, dal nome dello scienziato indiano Subramanyan Chandrasekhar che lo calcolò negli anni trenta, è il massimo valore della massa che può avere una stella nana bianca in condizioni di stabilità. Questo valore è di 1,44 masse solari. La vita di una stella è una incessante lotta tra la il peso della stella stessa, che tende a schiacciarla, e qualcos'altro che vi si oppone. In base alla densità della stella, la pressione che si oppone alla gravità è fornita da: Plasma stellare (stelle normali) Gas che, a causa della elevata temperatura, è formato da atomi "spezzati" in elettroni e ioni positivi. Come tutti i gas, si comporta seguendo la legge fondamentale dei gas PV=nRT. La pressione che bilancia la gravità delle stelle è dunque l'agitazione termica del plasma che è proporzionale alla sua temperatura. Plasma "degenerato" (stelle nane bianche)
