Are neutron stars and quark stars immortal?

[Leiningen]

Hello!

You won't remember me, I have been here once more than a year ago with a few questions. Now I have a new question. If proton decay destroys all "normal" objects in the universe, what will happen to neutron stars and quark stars?
The wikipedia says:
--- Although the phenomenon is referred to as "proton decay", the effect would also be seen in neutrons bound inside atomic nuclei. ---
Is it the same with neutrons bound inside a neutron star? And what about quark stars? I don't like the idea that they are still there, after even the biggest black holes have vaporized via Hawking-radiation.

Hello!

Thank you for the link! But are there any statements about the possibility of the decay of neutron stars and quark stars? It's a rather long article, and English isn't my native language. I looked through it to have an overview, but couldn't find passages where my question is adressed...

FATE OF THE UNIVERSE>THE DEATH OF STARS>NEUTRON STARS
http://library.thinkquest.org/C01266...on%20stars.htm

A neutron star is essentially a giant atomic nucleus. The protons and electrons are squeezed together so tightly that they combine to form neutrons that are practically in contact with one another. The density within a neutron star is almost equivalent to the density of an atomic nucleus.

‘Yes, stars will die after the exhaustion of nuclear fuel, and as mentioned previously, a lot of heavy stars of the first generation has already died; but the heavy elements generated by these massive stars are recycled by supernovea and form the terrestrial planet and human. These heavy elements are also essential for the formation of light, stable and long lived stars in the later generations of stars in form of dust grains.’

Non-linear magnetic field decay in neutron stars

Abstract
There exists both theoretical and observational evidence that the magnetic field decay in neutron stars may proceed in a pronounced non-linear way during a certain episode of the neutron star's life. In the presence of a strong magnetic field the Hall-drift dominates the field evolution in the crust and/or the superfluid core of neutron stars.

Pretty interesting subject and I added a bunch of bookmarks during the search for these links-thanx.

I hope you find the answer and post it so I can know too.

Don't forget about bablefish and google scholar
