Scientists have discovered a very unique and bizarre pulsar by detecting millisecond bursts of gamma radiation. The pulsar is unique because it has a star orbiting it at an incredibly fast rate- 90 minutes- and an amazingly close distance. It set the record in those categories for any binary neutron star system ever discovered (the companion is not another neutron star, rather it “is the compact remnant of a star which has been orbiting the pulsar since earlier times.”).
I could understand this article thanks to the recent subject matter in class. The concept of a neutron star is incredible, that gravity can smash matter together in that way. I don’t understand nearly enough about quantum physics to know why or how neutrons have a degeneracy pressure; what are they made of that can repel or not stick together? I always thought of them as essentially being solid mass. It just seems really strange, that you could have a ball of neutrons without it being a singularity ie black hole.
