The anomaly in data from the European Space Agency’s (ESA) Gaia sky-mapping satellite is believed to be a “legendary star” – a boson – made of dark matter.
Astrophysicists Alexandre M. Bombo and Inppocracis D. Saltas from the Institute of Physics of the Czech Academy of Sciences have analyzed data from Gaia capturing a pair of extremely strange objects, once thought to be a star orbiting a black hole.
It is a pair located 1.4 astronomical units apart (UU, approximately the size of the Sun-Earth) and orbits every 188 days.

According to Space, the first object in the pair is easy to explain. It is a star whose mass is about 0.93 times the mass of the Sun and whose chemical composition is similar.
But his companion is much more mysterious. Gaia data allows scientists “to weigh” it, showing that it is a massive object 11 times the mass of the Sun. However, this cannot be seen. It was something invisible.
Initially, it was suspected that it was a black hole. The black hole-stellar pairing is not unusual in the universe, in which a low-mass black hole formed from a massive star that ran out of energy, died and decayed. is collapsed.
But the parameters provided by the star system do not quite correspond to this hypothesis. People began to suspect that it must have been something much more exotic. ƝA new study, which has just been published online on arXiv, shows that it must be “boson star”.
Bosons are words that refer to particles that carry natural forces, for example ρhoton is a boson carrying the electromagnetic force. Dark matter is considered by astronomy to be a new type of boson, and since then the possibility of a hypothetical new object has been demonstrated which is a boson star, a star made entirely of dark matter.
Unable to see type “devil star” this directly, but can “see” indirectly through how it interacts with its surroundings, like a companion star.
Matching this hypothesis with data from Gaia, the Czech scientists think what may be confusing them is “The Legendary Star” there.
