Data for lodubay/galactic-dtd, a project exploring different models for the Type Ia supernova delay-time distribution (DTD) in multi-zone galactic chemical evolution models with the VICE package. This dataset contains two files: multizone.tar.gz is a compressed archive of all 33 multi-zone outputs (combinations of 8 DTDs x 4 star formation histories, plus one with an alternate stellar migration scheme), and sample.csv contains chemical abundance data from the APOGEE survey (data release 17) and stellar ages from Leung et al. (2023). This project is made reproducible with showyourwork, which will automatically download and extract all data from this deposit when it builds the article. This version contains a minor update to the APOGEE sample file.
