The early stages of a red giant star fit that description.
That depends on the star.
a super-nova
A 'nova'.
Cooler and Dimmer
The Universe is always expanding
the temperature of antares star is 3100 degreeC
the temperature of the pistol star is over 7,500 to about 10,000
A 'nova'.
Energy is absorbed in expanding and lifting the gas.
Cooler and Dimmer
by contracting and expanding
the surface of the star.
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.
