例句與造句

1. In 2005, using the Tip of the Red Giant Branch ( TRGB ) method, the distance was estimated to be.
2. Stars with a similar mass to the sun evolve towards the tip of the red giant branch with a degenerate helium core.
3. However, NGC 185 is close enough that the tip of the red giant branch ( TRGB ) method may be used to estimate its distance.
4. The tip of the red giant branch is such a method; every galaxy's brightest red giant stars must have exactly the same known luminosity.
5. These are thought to be stars contracting to the extended horizontal branch after a helium flash and ejection of their atmospheres at the tip of the red giant branch.
6. It's difficult to find tip of the red giant branch in a sentence. 用tip of the red giant branch造句挺難的
7. Stars too massive to develop a degenerate helium core on the red giant branch will ignite helium before the tip of the red giant branch and perform a blue loop.
8. Stars with masses similar to the sun develop degenerate helium cores after they leave the main sequence and ascend to the tip of the red giant branch where they ignite helium in a flash.
9. More recently, this inclined geometry for field stars in the LMC has been confirmed via observations of Cepheids, core helium-burning red clump stars and the tip of the red giant branch.
10. It is near the tip of the red giant branch with a stellar classification of M4 II . The outer envelope has an effective temperature of 4, 111 K, giving it the red-orange hue of an M-type star.
11. These include measuring the luminosity of planetary nebulae, comparison with nearby galaxies whose distance has been estimated using standard candles such as cepheid variables, the linear size distribution of globular clusters, . } } and the tip of the red giant branch method using individually resolved red giant stars, . } } These measurements are consistent with each other, and their weighted average yields a distance estimate of.
12. The thermal pulses become larger each time, with the later pulses pushing the luminosity to as much as 5, 000 times the current level and the radius to over 1 AU . According to a 2008 model, Earth's orbit is shrinking due to tidal forces ( and, eventually, drag from the lower chromosphere ), so that it will be engulfed by the Sun near the tip of the red giant branch phase, 3.8 and 1 million years after Mercury and Venus have respectively suffered the same fate.
