Which state of matter exists at the extremely high temperatures found on stars?

Long before when there were still 3 known states of matter to man which were the solid, the liquid, and the gas, the state of matter that existed at the extremely high temperatures found on stars is the gas state. After some time and with the help of scientific aid in this endeavor, a new state of matter was added to the original list which is the plasma. Plasma is like gas since it doesn't have any definite shape or volume. The thing is that its electrons are stripped off from their positions and form a sea of it making the matter conducive to electricity.
