... You may assume that the meteorite is a good conductor, so the heat is spread evenly throughout, that it is made of Iron, with a specific heat capacity of 450 J Kg -1 K -1 , and that it started off at a temperature of 270K. (Note - the the equation I ...
... However, stars with initial masses between about 0.8 Msun and 8 Msun (AGB stars) play an important role as the main site of the slow neutron capture (s-)process, which produces roughly half of the elements heavier than iron. ...
... These Type Ia supernovae (SNe Ia) are also the dominant contributor to iron-group nucleosynthesis and leading candidates for the elusive sites of high energy cosmic rays, the p-process isotopes, and the positrons responsible for the 511 keV annihilation ...
... last few days of the star's 10 million year life are spent burning Silicon into Iron ... Although iron can be fused into heavier elements such as Cobalt and Nickel, these ...
... Low and intermediate-mass red giant stars played an important role in this story, by producing much of the carbon, nitrogen, and fluorine, as well as up to half of all elements heavier than iron by the slow neutron capture process (the s process). ...
