Astronomers have observed huge stars disappear briefly behind celestial bodies of unknown origin

Sergey Koposov, an astronomer at the University of Edinburgh and co-author of this new study, said: “We just observed A dark, huge, slender celestial body passed between us and this distant star. This is so surprising, we can only speculate on its origin.”

This article was published in Research in “Monthly Notices of the Royal Astronomical Society” suggests several possibilities, but this dimming does not seem to be due to the inherent characteristics of the star itself-it must be a companion star bound by gravity.

Many WIT (full name What is this, which represents something that is not clear to astronomers) celestial bodies, which have some explanations: violent quasars, stellar collisions, and new stars. The team said this was almost certainly an occultation event.

They considered many different celestial bodies and ruled out the possibility of celestial bodies passing in front of stars in the universe. The huge disk of debris around white dwarfs and neutron stars is also unlikely to be the cause of the occultation, but the research team said that a cloud of dust, chaotic gas, and debris surrounding the black hole – a “black hole retreat disk” – May be the culprit.

The research team also identified two other candidate events, VVV-WIT-10 and VVV-WIT-11, which indicates that there may be more “winking giants” that need to be discovered and described.
