Astronomy 10 Chapter 11 1. Both used to be normal stars further the white dwarf ran out of hydrogen, they ar both subjected to gravitative theories. A Neutron star is a wandering of neutrons, as het at its rear as the in spite of appearance of the sun and has a great magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must pursue the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of shaft sickness that sweep slightly the sky as the neutron star rotates, and astronomers feel pulses when they sweep all over the Earth. 11. Sometimes in binary systems, mass flows into a fiery accretion disk about the neutron star and causes the emission of x rays. 14. Astronomers have found compacted objects greater than about 3 solar masses. Black great deals and neutron stars at the center of accretion disks can dispatch powerful beams of radiation and gas and such beams have been detected. risky gamma -ray bursts occur for womb-to-tomb than 2 seconds arise during hypernovae, the collapse of considerable stars to form char holes. Chapter 12 3. They can measure light curves of Cepheid variables in opposite galaxies in two nearby clusters. 5.

Because the gas and broadcast in the galaxy tends to redden and dim far outdoor(a) objects, the distant stars could not be peckn, so they could only see a minute part of the galaxy. 7. vitrine I Cepheids are macrocosm 1 stars with surface abundance similar to the sun. Type II Cepheids are population II stars with less metal determined by smartness and size. 9. Dark matter in the halo is demonstrated by its gravitational effect on a spiral galaxys rotary motion curve. W! ithout large amounts of mass in the extended halo, the rotational upper of the galaxy should decrease at large distance from the astronomic core 14. The center of the Milky appearance Galaxy is pronounced by a radio source, genus Sagittarius A, the motion of stars approximately the center shows that it must contain slightly 2.6 million solar masses; a super-massive black hole is...If you want to imbibe a full essay, order it on our website: OrderEssay.net
