Hey! I have a question, whose answer I was unable to get after reading some articles regarding neutron start. I've understood that neutron stars lose their rotational energy and emit fragments of it to earth, thus slowing down through the years. I know that this proccess takes billions of years (like every proccess out there!!! :), but I wondered if, out of all the neutron stars we have discovered - are there any who are not rotating at all? Or maybe rotating very slowly? Meaning, are there any n.stars known to us that have lost all their rotational energy? What happens then? Is it even possible to hunt them if they aren't rotating? Most of the energy they emit comes from the rotational energy - are they invisible to us when they stop rotating? Thanks! Tomer.
