BTW, how much could the Moon shield?

Probably not the entire Earth, but surely the "penumbra" of the star involved would be larger than the penumbra of the Sun. Assuming, again, that you were lucky enough to have the Moon in front of the star. In reality, odds are good that suspect stars aren't even in line with the Moon's orbit.
