Discussion Post #2- Types of Stars
ASTR 1000
Name:
Jerry Bhardwaj
Instructions: Please complete all questions asked below.
Discussion Prompts for Fi
rst Video
:
1.
What is the First Video you watched?
First video was about brown dwarves.
2.
Please give a summary of the Stellar Object/s discussed in the video. (at least 100
words)
When a star has barely enough mass to become a star, it might start the process like a normal star but
then not there might not be enough to generate it into a star. It would then just sit there and eventually
start cooling off, being named a red dwarf. The WISE found hundreds of brown dwarves and then
thousands, requiring new classifications to be created for the different types of stars. Some of these stars
are so dark that they emitted no light at all. Those that emit at least a little bit of light, the star would
actually be magenta. Even if you dump more mass, they won’t grow any bigger.
3.
Please list two (2) examples of this object and an interesting fact about each listed
item. (Example for Low Mass Stars: The Sun, Interesting fact: Orbited by at least
one planet with carbon-based life.)
Teide 1 was the first red dwarf found by using the L test in a nearby in Pleiades. Gliese 229 has methane
in it’s atmosphere which is super delicate.
Discussion Prompts for Second Video:
4.
What is the Second Video you watched?
Neutron Stars
5.
Please give a summary of the Stellar Object/s discussed in the video. (at least 100
words)
The contents of the neutron star are as bizarre as anything gets in the universe. It’s collapsing under its
own gravity. Under the huge pressure, they’ll create neutrons by crushing all the subatomic particles.
When there is a continued applied pressure that tries to push the neutrons together, it’ll run into a wall
and create a huge shock wave, creating an explosion and blowing the contents of the star into space. A
neutron star has the surface gravity 100 billion times stronger than earth’s. A neutron star can have a
magnetic field several trillion times stronger than the sun. Bell discovered the first ever pulsar, which is a
neutron star that spins rapidly with super strong magnetic fields launching twin beams of energy away
from the stars. Magnetars are a quadrillion time stronger than the sun.
6.
Please list two (2) examples of this object and an interesting fact about each listed
item. (Example for Low Mass Stars: The Sun, Interesting fact: Orbited by at least
one planet with carbon-based life.)
Neutron stars are so dense that it weighs 400 million tons in just a 6-sided die.
The first neutron star was detected in 1965 and then another one a few years later and
this time it was correctly identified as what it was.
