Low-mass stars end their lives here by ejecting their outer layers due to their thermal momentum during the planetary nebula stage, while high-mass stars have enough mass to survive this stage.
Stars form from collapsing cores of molecular clouds, and the core distribution is already skewed in that there are more low-mass nuclei than high-mass nuclei (this is actually observed in molecular clouds). So, of course, there are more low-mass stars than high-mass stars.
Both low-mass and high-mass stars begin to fuse hydrogen into helium, but high-mass stars burn hydrogen faster because the pressure and temperature at their core increases. The second difference is that you can create heavier elements.
The main difference between massive and low-mass stars at this point is the helium flash. Massive stars do not have helium fusion flashes. The exact stages of evolution are: Subgiant Branch (SGB) - combustion of hydrogen shell - expansion of the outer layer.

The Saros cycle is 18 years 11 1/3 days. Because of this 1/3 day means that the earth is 8 hours further along in its rotation than it was at the start of that cycle. the area previously facing the sun is now facing away.
<h3>Why don't total solar eclipses occur in the same places?</h3>
- When the Moon's shadow falls on the Earth, it causes a solar eclipse. They do not occur every month because the Earth's orbit around the sun does not coincide with the Moon's orbit around the Earth.
- The total solar eclipse of March 20, 2015 is part of the Saros 120 eclipse family. A Saros series is a collection of eclipses that are separated by 6,585.3 days from the next (or previous) eclipse.
- This equates to 18 years, 10 days, and 8 hours. The Saros period is unique in that any two eclipses separated by one Saros are very similar.
- The moon is nearly at the same position in relation to its node (the point at which the moon's orbit intersects Earth's orbit) and is also nearly the same distance from Earth. Furthermore, the eclipse occurs at nearly the same time of year.
- Three of the moon's orbital periods repeat after one Saros period of 18 years 10.3 days, resulting in these coincidences. The three periods are as follows:
