The Great Dimming of Betelgeuse
By: Tom Calderwood, Sky & Telescope Magazine – March 2021 Cover Article, MIT Graduate, leader- AAVSO Photoelectric Group.
Last year, Betelgeuse captured the headlines with its unprecedented fading. There was some speculation that the star might be on the verge of becoming a supernova. The last such event in the Milky Way blazed in our skies over 400 years ago, so interest was high, and astronomers around the globe were on alert. But what really happened? Tom Calderwood- author of “The Great Dimming of Betelgeuse”, S&T March 2021 Cover- will discuss the 2 competing hypotheses for sudden fading of Betelgeuse last year. He acknowledges that there is no universally accepted explanation for this star’s behavior. His talk will review scientific results to date with a special emphasis on work by the American Association of Variable Star Observers (AAVSO).
Tom Calderwood is the leader of the Photoelectric Photometry section of the AAVSO. He is the author of The Great Dimming of Betelgeuse, cover article for Sky & Telescope magazine’s March 2021 issue. He is a retired software engineer, holds a degree in mathematics from MIT, and is a member of the “Months of Betelgeuse” (MOB) professional research collective. Join us for this highly-informative presentation!
