- QUESTION 21 In a Type Ia supernova, the cause of the violent outburst is: 1) the sudden emission of a shell of stellar material from a dying low-mass star 2) the collapse of a very massive protostar to the main sequence 3) an enormous release of neutrinos during a sudden episode of hydrogen fusion 4) the transfer of so much mass from a companion star that a white dwarf goes "over the limit" and collapses, causing an enormous amount of sudden fusion 5) two neutron stars colliding with each otherarrow_forwardHow would the spectra of a type II supernova be different from a type Ia supernova? Hint: Consider the characteristics of the objects that are their source.arrow_forwardA supernova remnant was observed in 2007 to be expanding at a velocity of 14,000 km/s and had a radius of 6.5 light-years.
