Extremely bright supernovae may break the Chandrasekhar limit
London, UK (SPX) Feb 14, 2013
White dwarfs forming in extreme magnetic fields could be stabilized, allowing them to get bigger before they explode, leading to a brighter bang when they finally do, according to a team of researchers in India. Type Ia supernovae, caused by exploding white dwarfs, are often used by astronomers as "standard candles" to calculate the distance to a point in space because they are extremely bright and usually have similar luminosity. But some anomalously bright type Ia supernovae that scientists could not ... read more
