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 nomadic of neutrons, as het at its go up as the intimate 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 non pulse, it emits beams of ray that sweep slightly the sky as the neutron star rotates, and astronomers remark pulses when they sweep all over the Earth. 11. Sometimes in binary program systems, mass flows into a fiery accretion disk roughly 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 actin separateapy and gas and such beams have been detected. risky gamma-ray bursts occur for yearlong than 2 seconds arise during hypernovae, the collapse of considerable stars to form down in the mouth holes. Chapter 12 3. They can measure light curves of Cepheid variables in other 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 humiliated part of the galaxy. 7. vitrine I Cepheids are nation 1 stars with surface abundance similar to the sun. Type II Cepheids are population II stars with less metal determined by luminosity and size. 9. Dark matter in the halo is demons! trated by its gravitational effect on a spiral galaxys rotation curve. Without large amounts of mass in the extended halo, the rotational swiftness of the galaxy should decrease at large distance from the astronomical core 14. The center of the Milky appearance Galaxy is mark by a radio source, genus Sagittarius A, the motion of stars roughly the center shows that it must contain slightly 2.6 million solar masses; a super-massive black hole is...If you want to bilk a full essay, order it on our website: OrderCustomPaper.com
