The closest black hole to our solar system was discovered by studying the orbit of a star

This is the age of space exploration, and we couldn’t be happier to hear the words of an exoplanet, Black holeAnd a habitable world every few days. Currently, study Notice a sun-like star with a strange orbit.

The star’s orbital properties are so strange that scientists believe it must be part of a black hole binary system. If this international team of researchers is right, that makes it the closest black hole to our solar system.

In addition, this discovery indicates that there must be many dormant black holes scattered across the Milky Way, home to Earth.. Led by researchers from institutes as diverse as the Harvard-Smithsonian Center for Astrophysics, the University of California at Berkeley and your agency; The study was published in Monthly Notices of the Royal Astronomical Society.


The discovery of dormant black holes

Kareem El-Badri, a fellow of the Harvard Society, explained to Universe Today that these observations were part of a larger campaign to identify black hole companions lurking in regular stars in our galaxy.

“I’ve been searching for latent black holes for the past four years using a wide range of datasets and methods,” he said. “My previous attempts yielded a variety of binaries masquerading as black holes, but this was the first time the research had come to fruition,” he added.

The team used data acquired by the European Space Agency’s (ESA) Gaia Observatory to study the dormant black hole. The mission has been on its way for a decade. Measure the locations, distances and motions of more than a billion cosmic objects, whether they are stars, planets, asteroids or galaxies.

The researchers examined 168,065 stars in Gaia Data Release 3 (GDR3) that appear to have dual-body orbits. That’s when they found the star, which the scientists called Gaia BH1. Based on its orbit, they determined that the star must have a binary companion of black holes.

This may be the first time a black hole has been observed in the Milky Way without the use of X-ray emissions or other energetic emissions. Models predict that the Milky Way contains about 100 million black holes. But we’ve only observed about 20 of them. All the previous ones we’ve observed are in ‘X-ray binaries’: the black hole is eating a companion star, and it glows brightly in X-rays. The gravitational potential energy of this material is converted into light.

Al-Badri added, “But this is only the tip of the iceberg: a much larger population may be hiding, hiding in widely spaced dichotomies. The discovery of Gaia BH1 sheds early light on this group.”

The study has been published on the arXiv portal ahead of print and is awaiting peer review.
