wc star造句

例句与造句

1. Instead WC stars are found at lower luminosities, apparently post-red supergiant stars.
2. The expected progenitors of Type Ib supernovae, luminous WC stars, are not observed at all.
3. WO-type stars are extremely rare and all the known examples are more luminous and more massive than the relatively common WC stars.
4. By 2006, the abundances were measured as 55 % helium, 45 % carbon, and 5 % oxygen, typical of a WC star.
5. The ratio between the two types of Wolf-Rayet stars ( WC stars and WN stars ) in IC 10 is very different from the ratio in other galaxies in the Local Group, which may be somehow due to the starburst nature of the galaxy.
6. It's difficult to find wc star in a sentence. 用wc star造句挺难的
7. Thus the SMC is seen to have few WR stars compared to its stellar formation rate and no WC stars at all ( one star has a WO spectral type ), the milky way has roughly equal numbers of WN and WC stars and a large total number of WR stars, and the other main galaxies have somewhat fewer WR stars and more WN than WC types.
8. Thus the SMC is seen to have few WR stars compared to its stellar formation rate and no WC stars at all ( one star has a WO spectral type ), the milky way has roughly equal numbers of WN and WC stars and a large total number of WR stars, and the other main galaxies have somewhat fewer WR stars and more WN than WC types.
9. The maximum mass of a main-sequence star that can evolve through a red supergiant phase and back to a WNL star is calculated to be around in the milky way, in the LMC, and in the SMC . The more evolved WNE and WC stages are only reached by stars with an initial mass over at near-solar metallicity, in the LMC . Normal single star evolution is not expected to produce any WNE or WC stars at SMC metallicity.
