Abstract:Nova 1670 is a historical transient bearing strong similarities to a recently recognized type of stellar eruption known as the red nova, which is thought to be powered by stellar mergers. The remnant of the transient, CK\,Vul, is observable today mainly through cool circumstellar gas and dust, and recombining plasma, but we have no direct view on the stellar object. Within the merger hypothesis, we aim to infer the most likely configuration of the progenitor system that resulted in Nova 1670. We collected the … Show more
