The Milky Way's stray small star is shrapnel from the Big Bang of the White Dwarf.

A small star wandering in the Milky Way is likely to be a "shrapnel" from a large explosion caused by a white dwarf in a two-star system millions of years ago, the Australian National University has announced.
help people better understand the causes of star explosions and better study the accelerated expansion of the universe.
white dwarf is a low-light, high-density, high-temperature star.
named the White Dwarf because of its white color and relatively small size.
, according to Leia Ferrario, a professor at the Australian National University who was involved in the study, the mass of white dwarfs reaches 1. Four times, a thermonuclear explosion occurs, causing the total or partial destruction of the white dwarf, which in total produces the strongest and brightest Type Ia supernova.
Ia supernova brightness, can be used as a standard reference to measure the expansion of the universe.
did the white dwarf explode? There are currently two theories.
one believes that two white dwarfs combine to form a new super-high density white dwarf, and the other believes that white dwarfs devour their giant companions.
Ferrario says their findings support a second theory that white dwarfs devour their giant mates until they explode into a supernova.
Scientists at the Australian National University, in collaboration with their counterparts in the Czech Republic, Germany, Hungary, the United States and Canada, used multiple telescopes to observe the remainder of an Ia supernova explosion, code-ed LP 40-365, which passed through the Milky Way at a very high speed.
researchers have modeled it mathematically to determine its characteristics, including its density, temperature, and chemical composition.
On the basis of this study, the researchers believe that in a two-star system, a high-density white dwarf grabs material from its star companion, and as the white dwarf grabs more and more material, the situation spirals out of control, and a powerful thermonuclear explosion destroys the two-star system.
the size of a small star was thrown into the universe and flew for millions of years.
