No, i know proton and neutron but proton star? never heard of it, sorry

There cannot be proton stars.
Everything is electrically neutral in bulk. This is because the electric force is so strong that positive and negative charges seek each other out and cancel. So a proton star would be so fabulously positive it would blow apart.
A neutron star is formed when the pressure becomes so great it squeezes the electrons into the protons, yielding neutrons and neutrinos. Actually, during the formation of a neutron star in a supernova, so many neutrinos are produced that they push back against the infalling matter!
Proton decay has not been observed yet.

I don't know of any proton stars. Protons repel each other so a star of only protons is highly unlikely! http://chandra.harvard.edu/resources/faq/black_hole/bhole-65.html said that a star with enough gravity to make it happen would just turn into a black hole anyway! There are neutron stars in which gravity is so intense that the protons and electrons essentially fuse together into neutrons and you lose all the empty space in atoms in the process, making it incredibly dense, compact, and heavy. There is also such a thing as a protostar which is one of the early stages in star birth. That could be what you're thinking of.

No, their are no proton stars, the protons would not beable to stay together, they would repel each other, of course, speaking in that manner, a neutron star should magnetically fall apart so I guess I can't use that.
No, their has not been a star found mostly made up of protons. Neutron stars but not electron or proton stars.

I have no idea about proton stars.
Proton decay has never been observed or proved.
An experiment in japan placed the half life at more than 10^35 years.
The reason why it is excepted is it is required by some grand unification theories and it could give an explanation for the predominance of matter over anti-matter.
If it is observed it will give a great clue which GUT is correct.

I don't know if there is one all I saw were proton electronics, head lights for a car, and something about the sun is a proton star but thats questionable.

Never heard of a proton star..
I wonder where all the protons went to in a neutron star...

In a sense, almost all stars are "proton stars" since they shine by fusing hydrogen--which is just a single proton (with an electron to keep it company!).

No, because the reason it becomes a neutron star, is because all the electrons in the molecules are absorbed back into the protons in the nucleus, because of gravitational pressures, so then they become neutrons.

i've never heard of a proton star... do you mean neutron star? it is a star so dense that only neutrons can exist in it.
