Stars are born rotating. Observations of stars on their main sequence reveal that$\sim$  bulk of stars with mass above $\sim 1.5\mso$ are spinning fairly rapidly. While their pre-main sequence evolution is complex, a common assumption is that these stars reach a state of quasi-solid rotation when they start burning hydrogen at the zero age main sequence. From there on their evolution has to account for loss and internal redistribution of angular momentum. Stellar evolution models that include the   Low-mass stars evolve past the main sequence toward their red giant stage. In this phase the star experience
