A Romp with Betelgeuse
– Tom Calderwood
Last year, Betelgeuse entertained us 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? This month's speaker is ATMoB member, Tom Calderwood, and his presentation is titled "A Romp with Betelgeuse". He acknowledges 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 an ATMoB member since 1984 and the
leader of the Photoelectric Photometry section of the AAVSO. He is the author of The Great Dimming of Betelgeuse
, the cover
article of 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" professional research collective. I hope you can join us for his presentation!
