Briefings

A new study led by Rhys Seeburger of Liverpool John Moores University reveals that a previously suspected black hole system in the Large Magellanic Cloud is actually a rapidly spinning star. The research paper was posted to the arXiv preprint server on October 27, 2026, challenging the initial classification of the system as a black hole impostor.

Key points

• The system in the Large Magellanic Cloud (LMC) was initially thought to contain a star about five times the mass of the sun orbiting a stellar-mass black hole.
• The new study demonstrates that this is a black hole "impostor" system, meaning the object is actually a rapidly spinning star mimicking black hole behavior.

Context

Massive stars can mimic black hole behavior, leading to misinterpretation. This specific case involves a system in the Large Magellanic Cloud (LMC) cluster NGC 1850, where the initial classification was challenged by a new study.

Limitations

The evidence is limited to the provided text, which states the research paper was posted to arXiv on Oct. 27, 2026. No specific publication date, journal, or author details are provided beyond the lead researcher's affiliation.
