Which of the following is least reasonable regarding novae and supernovae?
Group of answer choices
A type I (carbon-detonation) supernova results when a white dwarf in a binary system absorbs enough mass from its companion to push it over the Chandrasekhar limit.
A type II supernova results from any supermassive star at the end of its life, when it runs out of fusion energy and collapses.
A nova can occur multiple times in a binary system.
If a white dwarf in a binary system absorbs enough mass to go beyond the Chandrasekhar limit, the white dwarf explodes as a supernova.
The reason a type I supernova does not produce hydrogen lines is that the explosion originates from a stellar core (white dwarf), where hydrogen has already fused to produce heavier elements (so there is no longer any hydrogen).
More supernovae are observed in the Milky Way because they are much closer to us than those in other galaxies.
1. The neutrino flux from SN 1987A was estimated to be 1.3 x 1014 m-2 at the location
of Earth. If the average energy per neutrino was approximately 4.2 MeV, estimate
the total amount of energy in joules released via neutrinos during the supernova
explosion. (SN 1987A was located in the LMC at a distance of 50 kpc.).
Indicate whether the following are properties of Type Ia or Type II supernovae.
(Select 1-Type Ia, 2-Type II. If the first is 1 and the rest 2, enter
12222222).
A) Produces very heavy elements like Uranium during the explosion.
B) Can occur in a very old star cluster.
C) Supernovae of this type have the same peak luminosity.
D) Could completely explode and leave no remnant behind.
E) Can only occur in a binary system.
F) The spectrum shows very little Hydrogen.
G) Caused by a white dwarf exceeding the Chandrasekhar mass limit.
