The Helium Flash Occurs in a 2-Solar-Mass Star When

question 212

Multiple Choice

The helium flash occurs in a 2-solar-mass star when

• A) the core heats up from helium fusion and the gas does not expand to cool down and stabilize the temperature because the gas properties are controlled by degenerate electrons.
• B) convection within the star carries helium to the surface, where it shows its own characteristic spectrum for the first time.
• C) hydrogen fusion ceases abruptly, leaving only the fusion of helium to generate energy.
• D) the core temperature becomes sufficiently high for helium fusion for the first time.
