luminosity class उदाहरण वाक्य

उदाहरण वाक्य

1. This is reflected in its uncertain luminosity class, between IV ( the subgiants ) and V ( main sequence dwarf star stars like the Sun ).
2. The spectrum of this star matches a stellar classification of G2 IV, with the luminosity class of'IV'indicating this is a subgiant star.
3. This star has a stellar classification of F2 Ia, with the'Ia'luminosity class indicating this is a supergiant more luminous than typical supergiants.
4. The luminosity class of IV indicates that this is a Sun's radius and an effective temperature of 12, 800 K in its outer envelope.
5. Accurate calibrations are available for the temperatures of class O stars, although these are slightly different for SMC metallicity and for stars of different luminosity classes.
6. HD 50064 has variously been assigned spectral types of B6, B9, and B1, and is readily seen to have a bright supergiant luminosity class.
7. The luminosity classes of O-type stars are assigned on the relative strengths of the He II emission lines and certain ionised N and Si lines.
8. A luminosity class of'III'indicates this is a giant star that has exhausted the hydrogen at its core and evolved away from the main sequence.
9. The stellar classification of Alpha Fornacis is F8IV, where the luminosity class IV indicates this is a subgiant star that has just evolved off the main sequence.
10. The luminosity class could not be determined with certainty, but a supergiant can be ruled out and the line widths suggest a giant class is most likely.
