Table A.1.

Reactions triggered in the originally catalyzed compressed outer crust (calculated in the MB model) up to the first neutron emission. Nuclei based on experimentally determined masses from AME2016 are presented in bold. The neutron-drip points calculated in the continuous approach are presented in blue. In order of columns, we give the pressure P in ( dyn/cm2), the density ρini right before the reaction, λ = Δρ/ρ the relative change in density due to the reaction in percent, the reaction concerned, the energy per nucleon Q of the reaction, the compression ΔP at which the reaction is triggered, and the relative compression δP/P in percent at which the reaction is triggered. The table is separated into 24 parts, one for each shell: the first line (before the dashed lines) includes the top pressure and density of the original shell (first and second column) as well as the nuclei of the shell. An electronic form is available at the CDS.
