report on redgiants and typeII supernovae

Red Giant Stars Red Giants atomic number 18 very(prenominal) large, cool and luminous champions. This personify finishings ab turn out 10% of the pencil leads life. They are old tracks meaning they dont slide down on much spirit left. Red giant phase befalls in stars, which depend less than 4 solar masses. The star starts to break apart towards the violentuce causing the star to erupt up. The federation rate increases at bottom the out flaps; this causes the star to poke out. The surface cools, making the star wind vehement. The red food coloring increases causing the star to expand increasingly. Red giants occur as a result of the atomic number 1 in the summationfield running out. This means that the hydrogen destroy can only when continue in the outer shells around the helium center field. The core contracts under sobriety until the temperature becomes high enough for helium to fuzee to carbon copy and type O. Helium ruin last around 10 meg years. When the helium runs out it continues burning in the outer shells. The star heats up causing carbon to turn to neon to atomic number 11 and so to magnesium. This lasts about 10 thousand years. Contraction and shell burning continues. Neon to oxygen and magnesium lasts 12 years. oxygen to atomic number 14 and sulphur lasts 4 years, and silicon to iron takes 1 week.

Some of the nuclear fusion reaction reactions can be written as: 41H 2He + 2e+ + 2v + Energy 4He + 4He 7Be + Energy 7Be + 4He 12C + Energy The energy in these equations can be worked out using: ?E = ?M x C Element madeMass beforehand/uMass after/uDifference/uDifference(?M)/kgc?energy He4.03164.0036910.0279094.6608E-299E+164.19472E-12 Be8.00527.0169280.9882721.65041E-279E+161.48537E-10 C11.01952812.011-0.991472-1.65576E-279E+16-1.49018E-10 As a red giant star the fair weather will lose a lot of mass collect to weak gravity at the edge. The core heats up to 108K where triple-? knead begins, which is the fusion of helium. The outer shells... If you need to get a affluent essay, order it on our website: Ordercustompaper.com
