main sequence
yes
The HR diagram does not reference stars on their way to the main sequence, only during or after.
The temperature of main sequence stars can vary quite a bit.
Beacuse they are dimmer, but they're also bigger than the main sequence stars.
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.

No. Main sequence stars are simply stars that are fusing hydrogen into helium and have a specific relationship between color and luminosity. They range from red dwarfs to large O-type main sequence stars.
Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion.

In the HR-diagram, a diagram of color vs. luminosity, most stars are concentrated close to one curve, called the "main sequence". It turns out that stars on the main sequence are the stars that mainly get their energy by converting hydrogen into helium.
There are billions of stars that are not on the main sequence.
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" is the tern.
Most of the stars in the universe are found on the main sequence. Stars fall off the main sequence when they begin to die.
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
