what mechanism make them to re-explode? what are symbiotic novae ?
A symbiotic nova is a type of stellar explosion that occurs in a binary star system, where one star is a white dwarf and the other is either a red giant or a main sequence star. The white dwarf accretes material from its companion, causing a thermonuclear explosion that releases a large amount of energy.
Symbiotic novae are unique because they occur in a binary star system, whereas other types of novae occur in single stars. Additionally, symbiotic novae have longer outbursts and lower peak luminosities compared to other types of novae.
A symbiotic nova is triggered by the accretion of material from the companion star onto the white dwarf. As the accreted material builds up on the surface of the white dwarf, it eventually reaches a critical mass and ignites in a thermonuclear explosion.
Symbiotic novae can have a significant impact on their surrounding environment. The explosion releases a large amount of energy and can create shock waves that can heat up and ionize the surrounding gas. This can lead to the formation of new stars and planets in the vicinity.
Yes, symbiotic novae can provide valuable insights into the evolution of stars in binary systems. By studying the outbursts and characteristics of symbiotic novae, scientists can better understand the processes of accretion, mass transfer, and stellar explosions in binary systems.
