Key achievements
Has made outstanding contributions in the variable star field
Goodrich was born in the Netherlands in 1764. When he was young, he became deaf and mute due to fever.As a teenager, he developed a deep interest in the stars.In the winter of 1782, Goodrich, who was less than 20 years old, continuously observed the variable star Darlingwu (Perseus beta) in the constellation Perseus. He estimated its light variation period to be 2 days, 20 hours, 49 minutes and 8 seconds, and proposed the light variation mechanism of Darlingwu. He believed that Darlingwu was a binary star system consisting of two stars, one bright and one dark. The two stars circled each other. When the two stars covered each other,The overall brightness darkens.In 1888, the German astronomer Vogel confirmed the idea of Goodrich by using the spectral method.This kind of binary star is called eclipsing binary star, or eclipsing variable star.In May 1783, GoodrichRoyal SocietyHe reported his theory and won the Copley Medal of the Royal Society.[1]
In the next two years, Goodrich discovered two other variable stars: Beta Lyra (Chinese name is gradually Taiwan II) and Delta Cepheus (Chinese name is Cepheid I).Goodrich correctly pointed out that δ Cepheus is a variable star whose luminosity is changing in the real sense.A large class of stars represented by δ Cepheus is called Cepheid variable stars.
In 1786, Goodrich was electedRoyal Societymember.Two weeks later, Goodrich, under 22, died of overwork.
