Students have asked these similar questions
Where does gold (the element) come from?
A. It is produced during the supernova explosions of high-mass stars.
B. It was produced during the Big Bang.
C. It is produced by mass transfer in close binaries.
D. It is produced during the late stages of fusion in low-mass stars.
Which of the following statements about novae is not true?
A. A nova involves fusion taking place on the surface of a white dwarf.
B. A star system that undergoes a nova may have another nova sometime in the future.
C. Our Sun will probably undergo at least one nova when it becomes a white dwarf about 5 billion years from now.
D. When a star system undergoes a nova, it brightens considerably, but not as much as a star system undergoing a supernova.
Is the answer C? Since the sun has no companion star, it cannot gain accreted matter to initiate a nova and so it would not undergo a nova, it would just undergo a type I supernova?
Thanks!
A helium flash occurs
a.
because helium is very explosive and cannot be controlled when the nuclear reactions occur.
b.
because degenerate electrons in the core do not allow the core to expand as it heats up.
c.
in Cepheid variables.
d.
in stars with masses less than 0.4 M.
e.
under none of the above conditions.
