An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on CK Vulpeculae (CK Vul), a nova that was well documented between 1670 and 1672 that left a bipolar nebula. A team of researchers led by Stewart Eyres of the University of South Wales used the ALMA radio telescope to analyze that explosion’s remnants, concluding that it was caused by the collision between a white dwarf and a brown dwarf, the first anomalous nova of this type identified.
