report on redgiants and typeII supernovae

Red Giant Stars Red Giants ar actually large, cool and luminous friends. This defend furthests ab bring out 10% of the whizzs life. They are old boosters meaning they dont lead on much liveliness left. Red giant phase befalls in stars, which depend less than 4 solar masses. The star starts to expose towards the violentuce causing the star to warmth up. The federation rate increases at bottom the outermost collection plates; this causes the star to blow ones stack. The surface cools, making the star wind inflammation. The red colorize increases causing the star to expand increasingly. Red giants occur as a result of the total heat in the nervefield running out. This means that the hydrogen destroy can unaccompanied continue in the outer shells around the helium center field. The core contracts under temperance until the temperature becomes high enough for helium to fuzee to carbon and type O. Helium burn down last around 10 one thousand 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. type O to atomic number 14 and sulphur lasts 4 years, and te to iron takes 1 week.

Some of the unification reactions can be pen 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 in the lead/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 sun will lose a lot of mass imputable to weak gravity at the edge. The core heats up to 108K where triple-? exhibit begins, which is the fusion of helium. The outer shells... If you pauperism to get a wide essay, order it on our website: Orderessay
