Nucleosynthesisneutron capture reactionsstellar evolutionNeutron reactions are responsible for the formation of all elements heavier than iron. The corresponding seenarios relate to helium burning in Red Giant stars (s process) and to supernova explosions (r and p processes ). These processes are ...
As this red giant swelled with age, this matter poured on its white dwarf companion, occasionally triggering explosions known as novas. Enough material eventually poured onto this white dwarf to set off a far more powerful supernova. The researchers estimate that novas give rise to more than ...
supernovae: generalsupernovae: individual (SN 1989B, SN 1998bu)M66 and M96 in the Leo I Group are nearby spiral galaxies hosting Type Ia supernovae (SNe Ia). We estimate the distances to these galaxies from the luminosity of the tip of the red giant branch (TRGB). We obtain VI ...
A red giant star (foreground) loses its outer layers due to solar wind and the material is accumulated by a nearby white dwarf star, which eventually triggers a supernova explosion like the observed PTF 11kx. Released Aug. 23, 2012.(Image credit: Romano Corradi/Instituto de Astrofísica de...
Stars like the Sun last for billions of years before they swell into a Red Giant and then throw off their outer layers to leave behind a tiny white dwarf remnant. However, much larger stars shine much brighter and burn out far quicker....
The glowing core, called a white dwarf, is left to cool for eternity. More massive stars exit the red giant stage with a bang, transformed by a supernova (explosion) into a neutron star (dense, neutron-filled remains of a star) or a black hole (a single point of infinite mass and ...
A Screenshot of Red Giant Supernova So, how much does it cost? Red Giant has two different levels of access to the Universe, Free and Premium.Free membership gives users access to 31 free plug-ins, 22 effects and 9 transitions.

Red Giant has also created a wonder developer’s tool known as Supernova. The developer’s tool allows you to create, manage and even update various plugins. The only real limitation seems to be your imagination. Supernova will make it easier for developers to create plugins that are needed...
planetary nebulas. Apparently most massive stars manage to lose sufficient material that their masses drop below the critical value of 1.4 M⊙ before they exhaust their nuclear fuel. Evidence supporting this view comes from observations of IRC+10216, a pulsating giant star (a star of great ...
