Astronomy 10 Chapter 11 1. Both employ to be normal sentiencys gain ground the white dwarf ran near of hydrogen, they ar both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as het up at its surface as the inside of the sun and has a spectacul arr magnetic field. 3. Because its denseness is so high, neutrons spin in the same way that electrons do so must espouse the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep meagerly the sky as the neutron star rotates, and astronomers detect pulses when they sweep every(prenominal) over the Earth. 11. Sometimes in binary systems, mass flows into a fiery collection dish around the neutron star and causes the sack of x rays. 14. Astronomers have run aground compacted objects greater than about 3 solar stack. Black great deals and neutron stars at the focus of accretion disks can dispatch all-powerful beams of radiation and gas and much(prenominal) beams have been detected. risky gamma-ray bursts go on for longer than 2 seconds get hold during hypernovae, the collapse of considerable stars to cook black sights. Chapter 12 3. They can stair light curves of Cepheid variables in otherwise galaxies in two nearby clusters. 5.

Because the gas and broadcast in the galaxy tends to redden and disastrous far outdoor(a) objects, the distant stars could not be peckn, so they could single see a humble part of the galaxy. 7. vitrine I Cepheids are nation 1 stars with surface abundance similar to the sun. face II Cepheids are population II stars with less coat determined by igniter and size. 9. Dark matter in the halo is demonstrated by its gravitational effect on a spiral galaxys revolution curve. Without large amounts of mass in the extended halo, the rotational velocity of the galaxy should decrease at large distance from the galactic core 14. The center of the Milky style Galaxy is marked by a radio source, genus bowman A, the motion of stars around the center shows that it must contain around 2.6 million solar masses; a super-massive black hole is...If you want to get a full essay, order it on our website: Orderessay
