The B2FH paper supported Fred Hoyle’s hypothesis that all elements heavier than this element were not formed through BBN. For 10 points each:
[10h] Name this element that is proposed to sink beneath a star’s atmosphere over time, thus increasing the rate of turbulent mixing. This element is the heaviest whose distribution is depicted on the Schramm plot.
ANSWER: lithium [or Li; accept lithium-7 or Li-7]
[10e] The brown type of these stars can be identified via the relative abundance of lithium. The white type of these low-mass stars forms after sun-like stars run out of fuel.
ANSWER: dwarf stars [accept brown dwarfs or white dwarfs]
[10m] A major source of lithium is the “classical” type of these phenomena, which are about 1,000 times brighter than their “recurrent” type. The “dwarf” type of these phenomena necessarily occurs [emphasize] below the Chandrasekhar limit.
ANSWER: novae [or novas; accept classical novae or recurrent novae or dwarf novae; reject “supernova” or “kilonova”]
