This hypothetical event has been dubbed 'bosenova,' which is an end stage of a kind of star known as a boson star.

However, it is difficult to determine what sort of particles it is formed of. Scientists look for theAccording to the study paper posted on the pre-print server, the "accumulation of ultralight dark matter " may result in the production of boson stars.

As boson stars aged, they gradually gained mass by devouring dark matter or swallowing other boson stars., the compact star would eventually pack so much mass within it that the energy of the dark matter could no longer resist the force of gravity, causing the boson star to collapse. The boson star would gradually approach this point of excessive mass buildup. When so much matter is squeezed together, they will begin to collide with one another, releasing high bursts of energy in the process.But how would scientists be able to detect these? Advanced detectors may be able to ultralight dark matter in the future.

“Many experiments around the globe are already searching for lightweight dark matter. A bosenova would appear to these detectors as a surge of dark matter coming from a specific direction in the sky, just like a traditional supernova appears as a surge of light,” mentioned the report.In a broad class of theories, the accumulation of ultralight dark matter with particles of mass 10−22 eV<mϕ<1 eV leads the to formation of long-lived bound states known as boson stars.
