Question

Note to moderator: Please read the answerline carefully.The dynamics of this process requires spherical symmetry breaking instabilities like the lepton-number emission self-sustained asymmetry and the SASI. The asymmetry of this process imparts a natal kick velocity. The chief physical mechanism for this process requires neutrino heating in the turbulent gain region. This process begins with a shock wave that eventually stalls due to the ram pressure of accreting material. (-5[1])Towards the end of this process, the rate of the decline from the “plateau” phase to the “radioactive tail” phase on (*) light curves is governed by nickel-56 abundance. When temperatures reach 10 billion Kelvin during this process, photodisintegration occurs. (-5[1])Supernovae that occur via this process (10[2])can form neutron stars and black holes, (10[1])unlike those that occur (10[1])when a white dwarf exceeds (10[1])the Chandrasekhar mass. For 10 points, what process is the implosion of the center (10[1])of a massive star? ■END■ (10[2]0[1])

ANSWER: core collapse [or core-collapse supernovae; prompt on collapse; prompt on CCSNe; prompt on stellar explosions or supernovae or SNe or Type Ib (“one-B”) supernovae or Type Ic (“one-C”) supernovae or Type II (“two”) supernovae or Type II-P supernovae or Type II-L supernovae or Type IIb supernovae by asking “what physical process is the mechanism for the supernova?” until “supernova” is read; reject “Type Ia (“one-A”) supernovae” or “thermonuclear explosions” or “thermal runaway”] (SASI stands for standing accretion shock instability.)
