In one way, yes. If the white dwarf is in a close binary system with another star, when that star expands into a red giant, the white dwarf can start siphoning gas from it. Eventually the heat and pressure of the accumulated gas ignites nuclear fusion, triggering a Type 1a supernova.
If the sun were to run out of fuel, it would eventually expand into a red giant, consuming Mercury and Venus, and possibly Earth. After this phase, it would shed its outer layers to become a planetary nebula, leaving behind its core as a white dwarf. The white dwarf would slowly cool and fade away over billions of years.
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.
A white dwarf that has stopped radiating energy would essentially cool down and fade away into a black dwarf. This cooling process can take billions of years, during which the white dwarf becomes invisible to telescopes that detect radiation and can only be inferred by its gravitational influence.
There are not black dwarfs. It would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of the universe.
A white dwarf is the remnant of a star like our sun which forms when the stars runs out of elements to fuse. As such it will not kill you directly but if you were on the earth then you would freeze to death because the sun would no longer be producing the amount of heat that it does now.There are however situation where a white dwarf could kill you directly. When a white dwarf is in orbit round a normal star in a binary system, it is possible for the white dwarf to 'steal' gas from its companion. This hydrogen gas can accumulate on the what dwarf's surface and may periodically explode as a 'nova'. If, over time, enough material is stolen to make the white dwarf heavier than 1.4 solar masses (the Chandrasekhar limit), it will then explode as a type 1a 'super nova' which will destroy the white dwarf completely. If you were on a planet orbiting a star near such an explosion, it would kill you.
If a white dwarf gained enough mass to reach the 1.4 solar-mass white dwarf limit, it would undergo a catastrophic event known as a Type Ia supernova. This explosion would release a tremendous amount of energy and result in the complete destruction of the white dwarf.
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
When a black hole collides with a white hole, it is theorized that they would cancel each other out, resulting in the release of energy and potentially creating a new type of cosmic event.
When a white hole and a black hole collide, it is theorized that they would cancel each other out, resulting in the release of a burst of energy. This event is purely hypothetical as white holes have not been observed in nature.
Convert into a dwarf white star which is really hot, then a neutron star, and finally, a black hole.
That would be "Procyon". Since its mass is only about 1.5 times the mass of our Sun, I would expect it to become a white dwarf.
If a dwarf star crashed into a planet,the planet would likely explode.
Not exactly. A white dwarf would be hard to see from Earth, and Sirius is the brightest star from our point of view. Sirius has two components; one of them, Sirius B, is a white dwarf.
Before a white dwarf, a star would undergo the red giant phase. After a white dwarf, a star may end its life cycle as a black dwarf, although no black dwarfs are currently known to exist in the universe due to the long timescales required for a white dwarf to cool down.
