Round 1: Tossup 4

Given these particles’ mean lifetime of 880 seconds and the time from freeze-out to the onset of BBNS, (10[1])one can calculate an abundance denoted Y. The timescale of these particles’ capture differentiates two reactions that occur in AGB stars and during supernovae, called the s- and r-processes. A different particle (-5[1])decays into one of these particles in the first step of the p-p chain. [emphasize] Above the Chandrasekhar (“chun-druh-SHAY-kur”) limit but below the TOV limit, these particles’ (10[1])degeneracy (10[1])pressure keeps massive stars (-5[1])from turning into black holes. (10[1])Pulsars are rapidly rotating (-5[1])members of a class of extremely dense stars made of these particles. (10[1])For 10 points, name these subatomic particles with no charge.
