Astrophysicists have finally solved a mystery lasting almost 350 years to uncover the first documented merger between a white and brown dwarf star.
Père Dom Anthelme, a French astronomer and monk, described a vivid outburst in the skies below the constellation Cygnus, which is shaped like a swan, back in 1670. Scientists have long believed the star in the constellation dubbed CK Vulpeculae to be a nova, a type of star that suddenly flares up, shining bright for a while before fading out.
Novas - Stars - Type - Classica - Novas
Novas are created when two nearby stars begin merging together. The most common type, dubbed classica novas, are between a white dwarf and a main sequence, sub-giant, or red giant star. The white dwarf starts sucking material from its companion to create a shroud of hydrogen gas around it. As it heats up, the gas reaches a temperature hot enough to begin fusing, reviving the leftover dead core temporarily.
The explosion spotted in 1670 isn’t a classic nova however, according to a group of researchers. In a paper published in the Monthly Notices of the Royal Astronomical Society, the team claim that the source of brightness is, in fact, between a white and brown dwarf star - the first of its kind.
