Question

After these stars undergo the helium flash, they enter the horizontal branch and then travel along the asymptotic giant branch. For 10 points each:
[10e] Give these post-main sequence stars named for their color and large size. The Sun will become one of these stars before becoming a white dwarf.
ANSWER: red giants [or red giant stars or red giant branch stars; prompt on giant stars]
[10h] AGB stars are named for following the red giant branch of the H–R diagram while undergoing this doubly eponymous process, which causes a star's core to shrink as it radiates energy.
ANSWER: Kelvin–Helmholtz mechanism [or Kelvin–Helmholtz contraction; prompt on answers giving “KH” instead of “Kelvin–Helmholtz”; reject "Kelvin–Helmholtz instability"]
[10m] AGB stars can become Wolf–Rayet stars via a strong form of this phenomenon. The heliopause separates the interstellar medium from a region distinguished by this phenomenon.
ANSWER: stellar wind [or solar wind]
