Sentences with phrase «explosion of a white dwarf star»

Known as 2014J, this was a Type la supernova caused by the explosion of a white dwarf star, the inner core of star once it has run out of nuclear fuel and ejected its outer layers.

Neither study searched for the stars responsible for so - called type Ia supernovae, which are explosions of white dwarf stars that have grown overweight by feasting on material from a companion star.

Observations of the explosions of white dwarf stars in binary systems, so - called Type Ia supernovae, in the 1990s then led scientists to the conclusion that a third component, dark energy, made up 68 % of the cosmos, and is responsible for driving an acceleration in the expansion of the universe.

Not exact matches

Imagine being able to view microscopic aspects of a classical nova, a massive stellar explosion on the surface of a white dwarf star (about as big as Earth), in a laboratory rather than from afar via a telescope.

Type Iax supernovae may be caused by the partial destruction of a white dwarf star in such an explosion.

Type Ia supernovae are caused by the complete destruction of a white dwarf star in a thermonuclear explosion.

Professor Mould and his PhD student Syed Uddin at the Swinburne Centre for Astrophysics and Supercomputing and the ARC Centre of Excellence for All - sky Astrophysics (CAASTRO) assumed that these supernova explosions happen when a white dwarf reaches a critical mass or after colliding with other stars to «tip it over the edge».

Both occur in systems where two stars orbit each other: a white dwarf sucks away the outer layers of a larger companion star until the smaller star reaches a critical mass, causing an explosion.

My research concentrates on the study of exploding stars — mainly nova outbursts caused by thermonuclear explosions on the surface of white dwarfs in binary star systems.

Type Ia supernovae are fairly rare in the nearby Universe and represent the explosion of at least one white dwarf star in a binary system.

This animation shows the explosion of a white dwarf, an extremely dense remnant of a star that can no longer burn nuclear fuel at its core.

Archival work, of course, isn't exactly what most scientists dream to be doing at NASA, so in 1999 Dr. Livio began shifting his research, focusing on black holes, acceleration of mass, white dwarves, neutron stars and particularly on supernova explosions.
