Einstein’s theory of general relativity and quantum mechanics were among the most startling discoveries in the 20th century. Based on these theories, the maximum mass of a non-rotating non-magnetized white dwarf was found to be about 1.4 solar mass, known as the Chandrasekhar mass-limit. However, over the past decades, various researchers have indirectly predicted many sub- and super-Chandrasekhar limiting mass white dwarfs (white dwarfs which violate the Chandrasekhar mass-limit) from the luminosity based observations of peculiar type Ia supernovae. Several research groups worldwide, earlier proposed different models, including magnetic fields, rotation, modified gravity, noncommutative geometry, and many more, to explain these peculiar white dwarfs.
