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 legato of neutrons, as het at its locate as the intimate of the sun and has a greater 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 that sweep slightly the sky as the neutron star rotates, and astronomers let on pulses when they sweep all over the Earth. 11. Sometimes in binary star systems, mass flows into a fiery accretion disk slightly 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 radioactivity and gas and such beams have been detected. risky gamma-ray bur sts occur for drawn-out than 2 seconds arise during hypernovae, the collapse of considerable stars to form sour 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 gauzy part of the galaxy. 7. vitrine I Cepheids are cosmos 1 stars with surface abundance similar to the sun. Type II Cepheids are population II stars with less metal determined by lighter and size. 9. Dark matt er in the halo is demonstrated by its gravit! ational effect on a spiral galaxys whirling curve. Without large amounts of mass in the extended halo, the rotational pep pill of the galaxy should decrease at large distance from the astronomical core 14. The center of the Milky appearance Galaxy is marked by a radio source, genus Sagittarius A, the motion of stars virtually the center shows that it must contain slightly 2.6 million solar masses; a super-massive black hole is...If you want to sign up a full essay, order it on our website: OrderCustomPaper.com
