Deviations Of The Radiative Heating Rate Per Mass Unit Q R Abundance pattern with a 85 a good analytic approximation of the radioactive power per unit of mass by electrons and rays is q ;e(t)ˇ4 109t 1:3 day erg=s=g; (1) q ; (t)ˇ8 109t 1:4 day erg=s=g: (2) since the radioactive power of the actual elemental abundances of merger ejecta may deviate from the above approxi. Time evolution of the total radioactive heating rate per unit mass, 〈q〉, mass number 〈a〉, and temperature 〈t〉 (all mass averaged over the ejecta) for the 1.35–1.35 m ☉ (solid lines) and 1.2–1.5 m ☉ (dotted lines) ns mergers. The same method can be used to estimate the total ejecta mass of r process elements from macronova light curves. we use our model of the heating rate and apply this method to the gw170817 macronova to obtain robust limits on the total mass of r process elements produced. the structure of the paper is as follows. This is because the heating from electrons accumulated from earlier epochs eventually exceeds the generation rate of new electrons. the predicted late time light curves of single isotope kilonovae also have a dependence (equation ( 37 )) but modulated by an exponential factor that gives a steeper decline.

Physical property defining the amount of heat liberated in unit time in a unit volume of rock by the decay of unstable radiogenic isotopes; dimension: w m −3. geoneutrino . an electron antineutrino emitted in β decay of nuclei during radiogenic heat production caused by the decay of the unstable isotopes 238 u, 232 th, and 40 k. Radioactive heating rate per unit mass in ns merger ejecta due to the decay of r process material, calculated for the y e = 0.1 ejecta trajectory from rosswog et al. (1999) and freiburghaus et al. (1999). the total heating rate is shown with a solid line and is divided into contributions from β decays (dotted line) and fission (dashed line).
