List the sequence of events that lead to a white dwarf supernova. What are the remnants that are left behind?
Homework Answers
To understand white drarf supernova, we have understand life
cycle of star. when large nebula was formed, it originates stars
based on their size of nebula. when it is too small , then it will
turn into proto stars. if it has sufficient mass to form a star
then nebula turn into star. based on size of star , they will turn
into red giants and red super giants. red gaints and red super
gaints are formed when star runs out of hydrogen at its core and
starts fusing hydrogen into helium. once the star runs out of fuel,
the star will collapse under the influence of gravity. if it is
large star which is more than 8 solar masses, it will turn as
supernova or if it is less than 8 solar masses it will form as
planetary nebula. planetary nebula will turn into white dwarf.
stars which have more than 8 solar masses , which turn into super
nova will form neutron star of black hole.
so the sequence of events lead to white dwarf are small star,red
gaint, planetary nebula. most massive stars with 8 times mass of
sun or more are not become white dwarfs.they will end up as
blackhole or neutron star.

choose A B C D QUESTION 5 When astronomers look at globular clusters they don't see any stars hotter/more luminous than our Sun. What does this mean for the age of the globular cluster? The globular cluster doesn't have enough gravity to capture any stars more massive than our sun yet. The globular cluster is younger than the typical lifetime of a star like our Sun. The globular cluster is older than the typical lifetime of a star like our...

9/ the 2011 Nobel Prize in Physics was awarded to 3 men who study white dwarf supernova explosions, which are known as Type la supernovae. The following problem is designed to give you a feel for what they did, and the sorts of apparent brightnesses and distances they were working with. A typical Type la supernova explosion has a luminosity of 1.72 x 10^36 W. If we observe such a supernova to have an apparent brightness of 1.25 x 10^-17...
