Roughly 90% of a star's total lifetime is spent on the main sequence, where it fuses hydrogen into helium in its core. After this stage, the star will evolve off the main sequence and follow a different path, such as becoming a red giant or a supernova.
Roughly 98% of the solar nebula's mass consisted of hydrogen and helium gases. These two elements are the most abundant in the universe and are the primary components of stars like our sun.
It is estimated that around 275 to 7,000 stars are born each day in the observable universe. As for the number of stars that die each day, this is more difficult to estimate precisely, but on average, a few large stars likely go supernova every century in a galaxy like the Milky Way, which contains billions of stars.
There are estimated to be around 100 billion galaxies in the observable universe, with each galaxy containing hundreds of billions of stars. This means that the total number of stars in the observable universe is in the order of 10^24 (1 septillion) stars.
Many Hollywood stars support democratic values and policies such as social justice, diversity, and equal rights. Additionally, the entertainment industry often aligns with liberal ideologies promoting inclusivity and progressivism. Hollywood stars may feel that the Democratic party better represents their views and priorities.

most stars you see in the sky are main-sequence stars because stars spend most of there life time as a main secuence stars then they turn into red giants and enggulp the inner planets blow off there outer layer and become white dwarf the will eventually die and give off huge clouds off gas and will become a new star.
Percentage wise - all of them.There are a number that have progressed off of the main sequence:-Betelgeuse. CNO cycle.Rigel: Shell burning.
"main sequence" is the tern.
There are billions of stars that are not on the main sequence.
Of the stars you can see from Earth, 90% are in the main sequence.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
main sequence stars , our sun is also a main sequence star
main sequence stars , our sun is also a main sequence star
Main sequence stars include the hottest stars as well as the coolest ones.
