RX J1713.7-3946: Hadronic and Leptonic Energy Budgets at a TeV Shell

This paper computes the energy, density and acceleration budgets of RX J1713.7-3946 from a small set of adopted, published input values, using the relations stated in the Methods and a deposited script that reproduces every number. At the adopted density of one particle per cubic centimetre, the proton-proton loss time is 7.05e+07 years and the observed gamma-ray luminosity requires 5.34e+49 erg stored in protons, a fraction 0.0534 of a standard explosion energy. That fraction is squarely in the range that diffusive shock acceleration theory regards as efficient but not extravagant, so energetics alone cannot exclude the hadronic reading for this source, unlike the low-density case of SN 1006. The calculation is a computation from stated assumptions, not a measurement, and each headline result is reported together with the diagnostic that tests whether the assumed evolutionary phase applies to this object.
