spectral type การใช้

• Due to its dimness, insufficient data exists to determine its spectral type.
• This star was originally a standard for the B3 Ia spectral type.
• It is a yellow giant of spectral type G2Ib-II and lies away.
• The body's spectral type as well as its rotation period remain unknown.
• It has a spectral type of G5, while the luminosity class remains undetermined.
• Total apparent magnitude of 5.3 and integrated spectral type of B1.7.
• The spectral type can be determined by observing the star's spectrum.
• It is a variable star of average magnitude 6.53 and spectral type A1III.
• Its spectral type varies between M4 and M7 as it pulsates.
