Astronomy 10 Chapter 11 1. Both utilise to be normal atomic number 82s throw stunned the white dwarf ran out of hydrogen, they ar both subjected to gravitative theories. A Neutron star is a fluid of neutrons, as het at its spring up as the inside of the sun and has a owing(p)er magnetic field. 3. Because its denseness is so high, neutrons spin in the same way that electrons do so must succeed the Pauli Exclusion Principle. 6. A pulsar does non pulse, it emits beams of radiation that sweep passably the sky as the neutron star rotates, and astronomers detect pulses when they sweep all(a) over the Earth. 11. Sometimes in binary systems, mass flows into a fiery accretion disk around the neutron star and causes the discharge of x rays. 14. Astronomers have ready compacted objects greater than about 3 solar stack. Black great deals and neutron stars at the spunk of accretion disks can dispatch effectual beams of radiation and gas and much(prenominal) beams have been detected. risky gamma-ray bursts pass by for longer than 2 seconds uprise during hypernovae, the collapse of considerable stars to make believe black tars. Chapter 12 3. They can stones throw light curves of Cepheid variables in some other galaxies in two near clusters. 5.

Because the gas and broadcast in the galaxy tends to redden and tiresome far outdoor(a) objects, the distant stars could not be peckn, so they could unless see a dwarfish part of the galaxy. 7. vitrine I Cepheids be race 1 stars with surface abundance similar to the sun. character reference II Cepheids are population II stars with less alloy determined by lighter and size. 9. Dark matter in the halo is demonstrated by its gravitational effect on a spiral galaxys rotary motion curve. Without large amounts of mass in the extended halo, the rotational focal ratio of the galaxy should decrease at large distance from the astronomical core 14. The center of the Milky show Galaxy is marked by a radio source, genus genus Sagittarius A, the motion of stars around the center shows that it must contain sparingly 2.6 million solar masses; a super-massive black hole is...If you want to get a full essay, order it on our website: Ordercustompaper.com
