fusion is smooth, so the envelopes of these stars do not contract and the evolutionary tracks do not show the small leftward loop. 16.2 The H-shell Fusion Phase of Low-mass Stars of 0.8–2Mʘ We first describe the evolution of a 1Mʘ star as an example of the evolution of a star with 0.8 ≳ M ≳ 2Mʘ. In presenting the evolution of stars, we will discuss their tracks in the HRD ................
