New Model Reveals 'Kicks' in Sun-Like Star Death Throes
A recent study led by Caltech's Jim Fuller proposes a new model for the final stages of sun-like stars. As these stars age, they expand into red giants, gradually shedding their outer mass into space. Their remaining cores then contract to form white dwarfs, a common stellar endpoint across the universe. The new model suggests that this process of escaping mass from the stars' surfaces generates a series of "little kicks" during their death throes.

When stars similar to our sun reach the end of their lives, they undergo a transformation, first expanding into red giants. During this phase, their outer layers of material begin to bubble and are gradually expelled into space.
Following the red giant phase, the remaining core of the star contracts, forming a dense remnant known as a white dwarf. Given that most stars conclude their existence in this manner, white dwarfs are prevalent throughout the cosmos.
A new model, developed by Jim Fuller, a professor of theoretical astrophysics at Caltech, offers a fresh perspective on the final stages of sun-like stars. This model proposes that the mass escaping from the stars' surfaces during these death throes leads to a series of subtle "kicks."
According to Phys.org, this research introduces new insights into stellar evolution.
