“In a certain sense I made a living for five or six years out of that one star [Ï… Sagittarii] and it is still a fascinating, not understood, star. It's the first star in which you could clearly demonstrate an enormous difference in chemical composition from the sun. It had almost no hydrogen. It was made largely of helium, and had much too much nitrogen and neon. It's still a mystery in many ways ... But it was the first star ever analysed that had a different composition, and I started that area of spectroscopy in the late thirties.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The star ι Sagittarii showed an unusual chemical makeup, lacking hydrogen and rich in helium, nitrogen, and neon, revealing that stars can differ greatly from the Sun.
In simple terms: A star was found with a strange composition, unlike the Sun.
