Powerful superflares discovered erupting from superdense stellar corpse

(Image credit: LSU Prof. Robert Hynes, with his BinSim program)An uncommon type of white dwarf star has been emerging in the most severe superflares of its kind ever seen, scientists discover in a new study.The star in concern, known as V2487 Oph, is what astronomers call a reoccurring nova.”Until now, superflares had actually only been identified in “regular” star types like “regular” (non-recurrent nova) white dwarfs, giant stars, supergiant stars and more. Hence, in this case of an Earth-like world around the closest star, superflares preclude the development of life on any world in the system, and it makes the finest and closest world inhospitable for human colonization,” Schaefer added.While superflares on V2487 Oph appear to be regular, as Pagnotta revealed, the stars last nova occasion occurred in 1998, fading over a couple of weeks.

Therefore, in this case of an Earth-like world around the closest star, superflares preclude the formation of life on any world in the system, and it makes the finest and closest planet inhospitable for human colonization,” Schaefer added.While superflares on V2487 Oph seem to be regular, as Pagnotta exposed, the stars last nova event occurred in 1998, fading over a couple of weeks.
