(Select 1-Type Ia, 2-Type II. If the first is 1 and the rest 2, enter
12222222).
A) Can occur in a very old star cluster.
B) Can only occur in a binary system.
C) The spectrum shows strong Hydrogen lines
D) Produces very heavy elements like Uranium during the explosion.
F) Could completely explode and leave no remnant behind.
Supernovae of this type have the same peak luminosity.
Describe each of the following in detail, indicating their respective origins and the differences between them: Nova, Supernova type 1, Supernova type II.
Place the following events in the formation of stars in the proper chronological
sequence, with the oldest first and the youngest last.
w. the gas and dust in the nebula flatten to a disk shape due to gravity
and a steadily increasing rate of angular rotation
x. a star emerges when the mass is great enough and the temperature is
high enough to trigger thermonuclear fusion in the core
y. the rotation of the nebular cloud increases as gas and dust
concentrates by gravity within the growing protostar in the center
z. some force, perhaps from a nearby supernova, imparts a rotation to a
nebular cloud
