In your "life-cycle of a star" slide, there was a star category called "Black dwarf". What makes a black dwarf star and why are they different from brown dwarfs.
A main sequence star that lacks the mass necessary to explode in a supernova will become a white dwarf, a 'dead' star that has burned through all of its hydrogen and helium fuel. After enough time has passed, all of the leftover heat will have radiated away, it will no longer be emitting heat or light, the white dwarf will become a black dwarf. In this stage, it becomes incredibly difficult to find, making it an "invisible" black dwarf. -I hope this answered your question!

A neutron star is a type of compact star that can result from the gravitational collapse of a massive star after a supernova. Neutron stars are the densest and smallest stars known to exist
Young stars are not found in isolation, but are found in large groups. These groups are close to large clouds of molecular gas. The typical cloud is very large and very cold. The gas within the cloud has a density of over 1,000 molecules per cubic centimeter. This is the primary home for star birth.
Stars first give off visible light when the center of the protostar becomes hot enough to give off visible light and most of the cloud of gas and dust has fallen into it. So now it looks like a star. That takes about a million years, if the star is about the mass (weight) of our sun.

ReplyDeleteIn your last side you mentioned a star called a neutron star. What is a neutron star exactly?

ReplyDeleteCan an isolated star formation be created from more dense clouds as well or do they have to be small?

DeleteAt what point in the birth of a star does the star start giving off visible light and why?
