| Abstract: | The thermal stability of stars with a condensed core and an extended convective envelope (red giants) is discussed. It is shown that the thernal stability is determined by the way the opacity of the photosphere depends on density and temperature. In particular, the H? opacity in red giants' photospheres ensures their stability. |
