Chandrasekhar Limit: Definition, Derivation & Application

The super-Chandrasekhar mass white dwarfs that gave rise to these supernovae are believed to have had masses up to 2.4–2.8 solar masses. One way to potentially explain the problem of the Champagne Supernova was considering it the result of an aspherical explosion of a white dwarf. Visa mer The Chandrasekhar limit is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M☉ (2.765×10 kg). White dwarfs resist Visa mer Electron degeneracy pressure is a quantum-mechanical effect arising from the Pauli exclusion principle. Since electrons Visa mer The core of a star is kept from collapsing by the heat generated by the fusion of nuclei of lighter elements into heavier ones. At various stages of stellar evolution, the nuclei required for this process are exhausted, and the core collapses, causing it to become … Visa mer After a supernova explosion, a neutron star may be left behind (except Ia type supernova explosion, which never leaves any remnants behind). These objects are even more compact … Visa mer In 1926, the British physicist Ralph H. Fowler observed that the relationship between the density, energy, and temperature of white dwarfs could be explained by viewing … Visa mer In April 2003, the Supernova Legacy Survey observed a type Ia supernova, designated SNLS-03D3bb, in a galaxy approximately 4 billion light years away. According to a group of astronomers at the University of Toronto and elsewhere, the observations of this supernova are … Visa mer • Bekenstein bound • Chandrasekhar's white dwarf equation • Schönberg–Chandrasekhar limit Visa mer WebbThe Chandrasekhar Limit and the Fate of Stars. Between the ages of 18 and 28 (1929 to 1939) Chandrasekhar was intensely interested in the physics of stars – astrophysics. Traveling by ship in 1930 to begin his Ph.D. at Cambridge, he calculated a number. In his honor this number is now called The Chandrasekhar Limit.
