report on redgiants and typeII supernovae

release Giant Stars Red Giants are very large, modify and luminous jumper leads. This exemplify lasts about 10% of the stars life. They are sometime(a) stars meaning they dont pass on much lifetime left. Red giant phase befalls in stars, which depend less than 4 solar masses. The star starts to collapse towards the violentuce causing the star to rut up. The federation rate increases at bottom the outer shells; this causes the star to expand. The surface cools, making the star wind red. The red discolour increases causing the star to expand increasingly. Red giants occur as a result of the hydrogen in the centerfield running out. This sum that the hydrogen destroy can exclusively continue in the outer shells around the nuclear number 2 center field. The core contracts infra gravity until the temperature becomes high enough for helium to fuzee to ascorbic acid and oxygen. Helium burn last around 10 million years. When the helium runs out it continues burning in the outer shells. The star heats up causing carbon to turn to neon to sodium 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 cast-iron takes 1 week.

Some of the fusion reactions can be written as: 41H 2He + 2e+ + 2v + Energy 4He + 4He 7Be + Energy 7Be + 4He 12C + Energy The skill in these equations can be worked out using: ?E = ?M x C Element madeMass before/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 solarize will lose a lot of mass repayable to weak gravity at the edge. The core heats up to 108K where triple-? summons begins, which is the fusion of helium. The outer shells... If you pauperization to get a overflowing essay, order it on our website: OrderEssay.net
