Stephen Hawking's previous work has served to develop a curious theory.
The universe and the objects and celestial bodies that inhabit it are amazing and give us a dimension of how tiny the human being is in the global image of the cosmos. We can try to understand, for example, how black holes work or those explosions of stars called kilonovae. However, we still continue to reveal secrets of the cosmos and you are going to love this one.
The theory of the black hole-hunting star
Stephen Hawing postulated the existence of primordial black holes in one of his most famous articles. And now, a group of scientists of the Max Planck Institute for Astrophysics, wanted to create a model that demonstrates that these tiny black holes can be attacked by stars.
Did you know that there are three categories of black holes?

These primordial black holes they would have been formed in the first moments after the big Bang and, surprising as it may seem, they could be inside stars like the Sun, which would increase its own brightness.
The research, published in the scientific journal The Astrophysical Journaltheorizes about the so-called Hawking stars, which are those newly formed stars capable of capturing primordial black holes within them. Selma de Mink, director of the stellar department at the Max Planck Institute for Astrophysics, assures that:
Scientists sometimes ask ourselves questions to learn more. We don't even know if these primordial black holes exist, but we can still conduct an interesting thought experiment.
Big clues may be found in “mini” black holes. 👀

He created model during the investigation it could be one of the solutions that many astronomers and astrophysicists have sought to fill in the blank boxes that the evolution of stars. Furthermore, it can also serve to offer a new explanation to the existence of the dark matter.
The article, in addition to exploring the different phases that the Sun will go through, also recreates models with different stellar masses and metallicity to propose that the star structure that include a primordial black hole could be detected through a technique called asteroseismology. Matt Caplan, co-author of the study, says that:
Although the Sun is used as an exercise, there are good reasons to think that Hawking stars could be common in globular clusters and in galaxies with ultra-faint dwarfs. This means that Hawking stars could be a tool to test the existence of primordial black holes and their possible role as dark matter.
