Black Holes, White Dwarfs and other Dead Stars -Part 1

A description of the bizarre properties of stars at the end of their life, actually they are already dead as they no longer generate energy by Nuclear Fusion. These remnants: White Dwarfs, Neutron Stars, and Black Holes require quantum mechanics to fully describe their nature.

what is the smallest a star could be? 0.5 solar mass???

[jas2754]

About 0.1 Solar Mass

hahaha hopefully your still awake.

this type of science is the only one that interests me. i hate chemistry but astrology is quite something. for some reason when i think about space it makes me think that the things that humans do are pointless.

[jas2754]

You mean Astronomy. ;-)

If light is affected by gravity then how can light be used as a reference to a stars size? Well it looks like it is small and it is a very dense star with gravity 1.4 times that of our sun. Wouldn't the light be affected to where the star only looked smaller?

[jas2754]

An object of 1.4 solar masses will bend light indeed, especially if it is on the order of the dimaeter of the Earth. The estimate of 1.4 solar masses for the limit of a white dwarf does not come from observations... rather it is a prediction based on electron degeneracy.

There are no black holes, just brown stars waiting to go nova. Einsteins mass limit is the neutron star.

This is real helpful, thanks. :)

I came across this vid in hopes of helping me study for a tezt that is coming up, it was very helpful, thankyou for that first of all. But I was wondering if its not too much to ask to make a vid or explanation on how neutron/electron degeneracy pressure works. If not its ok :)

right. thats what i said... in my head XD
