Artist's concept of a luminous blue variable star (ESO/L. Calçada)

An article published in the “Monthly Notices of the Royal Astronomical Society” reports the mysterious disappearance of a massive star of the luminous blue variable type in the Kinman dwarf galaxy. A team of researchers led by Andrew Allan of Trinity College in Dublin, Ireland, detected the disappearance of that star using ESO’s Very Large Telescope (VLT) in Chile. Additional observations and research of archival data to try to better understand the events led to believe that the most likely possibilities are a transformation that led to a sharp drop in brightness, maybe dimmed even more due to the dust that covered it, and its direct collapse into a black hole without a supernova explosion.
