English
Noun
technetium star (plural technetium stars)
- (astrophysics) A star in which technetium has been detected. This is significant because technetium is too short-lived to occur primordially in the star, if the star is about 4.5 billion years old (the estimated age of the Earth), so the star must be producing technetium.
