The transformation of a main sequence star into a red
... Both, the core and the shell owe their stability to a property of stars which usually is referred to as negative heat capacity. A negative heat capacity of a system means that its temperature decreases when a heat flow enters it . However, the temperature decrease has to be paid for. It can be reali ...
