V1400 Centauri

V1400 Centauri, also known as 1SWASP J140747.93−394542.6 or simply J1407, is a young, 20-million-year-old pre-main-sequence star that underwent a series of extreme dimming events in April–June 2007. These dimming events, which never appeared again, were thought to have been caused by an eclipse of a disked object known as J1407b. The star is about as…
