Why are not giant stars in the main sequence on the H-R diagram?
Because there not that hot
What 2 types of stars can form from a nebula?
Two types of stars that can form from a nebula are main sequence stars, like our sun, and giant stars, which are larger and more luminous than main sequence stars.
What are the five main groups of stars?
The five main groups of stars are main sequence stars, giant stars, supergiant stars, white dwarf stars, and neutron stars. These groups are classified based on their size, temperature, and stage in their life cycle.
The two types of stars that do not fall into the main sequence of an H-R diagram are?
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
What is the step after main sequence in a stars life?
After the main sequence, a star becomes a red giant.

What two types of stars that can form from nebula?
Two types of stars that can form from nebula are main sequence stars, like our Sun, and giant stars, which are larger and brighter than main sequence stars. Main sequence stars fuse hydrogen into helium in their cores, while giant stars have expanded and evolved from the main sequence phase.
What 2 types of stars can form from a nebula?
Two types of stars that can form from a nebula are main sequence stars, like our sun, and giant stars, which are larger and more luminous than main sequence stars.
What sequence of stars is listed in order of increasing luminosity?
The sequence of stars listed in order of increasing luminosity typically includes red dwarfs, main-sequence stars (like our Sun), giant stars, and supergiant stars. Red dwarfs are the least luminous, followed by main-sequence stars, then giant stars, and finally supergiants, which are the most luminous. This order reflects the increasing energy output and size of the stars as they evolve.
What element is the main fuel for main sequence stars for red giant?
Main sequence star: hydrogen-1. Red giants: helium-4.
What are the five main groups of stars?
The five main groups of stars are main sequence stars, giant stars, supergiant stars, white dwarf stars, and neutron stars. These groups are classified based on their size, temperature, and stage in their life cycle.
Its Cooler larger and brighter than most main sequence stars?
red giant
How differ the sun and polaris?
The sun is a main sequence star whereas Polaris is a super-giant.
The two types of stars that do not fall into the main sequence of an H-R diagram are?
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
What stars have left the main sequence?
The main sequence stars are stars that fuse hydrogen, so the stars that have left the main sequence are the ones that have basically run out of hydrogen. They are the Red Giant stars, Supergiant stars and White Dwarf stars.
Are big stars cold?
No. All stars are hot. For stars on the main sequence, the largest it is, the hotter it is. When a star leaves the main sequence to become a giant or supergiant it will cool down, but will remain hot enough to glow brightly.
