Abstract

2.9.0 complete a stellar EOS with ideal gas and radiation (#1201) AmrexAstroCxxNetwork: check weak label in ydot_weak (#1216) change how DerivedRate works so it can apply to any strong rate (#1207, #1217) pin nbclient to fix doc build issues (#1214, #1220) standardize Rate.fname and Rate.id (#1209) optimize AmrexAstroCxxNetwork ener_gener_rate (#1210) and use exp10 for performance (#1215) remove Rate.cname and change Rate.fname to be more descriptive (#1206) add a TemperatureTabularRate that works with (T, N_A) pairs (#1175, #1191) update CI to python 3.14 (#1089, #1205) clean up the EOSState classes (#1200) update Zenodo authors (#1204) add a full_library that contains all the rates in pynucastro (#1193) add a unit test on rate IDs (#1199) add a solar composition from Lodders et al. 2020 (#1187) remove Rate.chapter outside of ReacLibRate (#1203) make tabular rates distinguishable (#1196) remove libfile from the Library class -- it only makes sense for ReacLibLibrary (#1185) docstring updates (#1198, #1208) remove list_known_rates -- it only works for single rate files (#1192) centralize the AMReX C++ interpolation routines (#1190) AMReX C++ networks optimizations: use the smallest int type for rate_indices (#1189), eliminate multiple logs in the table rate eval (#1180), remove unneeded parameters (#1183), cache partition function indices and only compute partition function if it is > 1 (#1165, #1167), optimize table lookup for weak rates (#1164) Add SECURITY.md (#1188) network_helper updates: add with_reverse (#1168), add inert_nuclei support (#1184) update CI actions (#1181, #1212) update CI benchmarks to reflect AMReX-Astro Microphysics changes (#1179, #1222) add more screening test coverage (#1172) docs / API link updates (#1170, #1174, #1218, #1221) add Windows CI test (#1163, #1177) disable CPU features when regenerating nets in CI comparisons (#1173) add the ability to plot partition functions (#1166)
