- stellar astronomy and atomic spectra
- Language:
- Czech
- Description:
- Double stars five us not only insight into stellar masses, dimensions, and luminosities (as has been appreciated for many years), but also clues as to the late stages of evolution, as in novae and combination variables, where late type giant or supergiant stars are paired with small, hot companions. Some even provide information on atomic spectra, notably iron, whose emission lines are displayed so prominently in objects such as XX Oph and RR Tel.
