- Neutrinos and SN 1987A (Tue Oct 6 7:00 pm)
A core-collapse supernova releases most of its energy as neutrinos. This theoretical conclusion is confirmed by a single event, the supernova seen in the Large Magellanic Cloud in 1987. Large neutrino detectors buried deep underground... - Core-Collapse Supernovae (Wed Sep 9 7:00 pm)
The most energetic supernovae are powered by gravitational potential energy. Once a massive star consumes all of its thermonuclear fuel, it is unable to support itself against its own gravity. The core of such a star collapses to... - Nuclear Reactions in Thermonuclear Supernovae (Tue Jun 2 7:00 pm)
Carbon and oxygen are converted into nickel in a white dwarf through a complex network of reactions. The incremental changes tend to follow the series of atomic nuclei that are multiples in composition of the helium nucleus. ... - Thermonuclear Supernovae (Fri May 1 7:00 pm)
Most type Ia supernovae are attributed to the thermonuclear explosion of white dwarfs. A star becomes a white dwarf before it has completely consumed its thermonuclear fuel. The amount of thermonuclear energy locked within a... - Energetics of Thermonuclear Supernovae (Fri May 1 7:00 pm)
The thermonuclear energy locked inside a white dwarf is sufficient to blow the star apart. In particular, white dwarfs composed of carbon and oxygen, which are more common and contain more thermonuclear energy than those composed...
