Description
Follow-up spectra and evolutionary models obtained for the manuscript "A hot subdwarf–white dwarf super-Chandrasekhar candidate supernova Ia progenitor", published in Nature Astronomy (https://doi.org/10.1038/s41550-021-01413-0).
This repository includes:
- Spectra taken with the Double-Beam Spectrograph at the Palomar 200-inch telescope, reduced with a PyRAF-based pipeline (https://github.com/ebellm/pyraf-dbsp). Files start with DBSP*, and are separated by spectrograph arm (blue or red). Flux (flux.spec) and flux error (flux.err) are in different files. We provide both fits and ascii files.
- Spectra taken with the Echellette Spectrograph and Imager (ESI) at the Keck II telescope, reduced with the MAKEE pipeline (http://www.astro.caltech.edu/~tb/ipac_staff/tab/makee). Fits and ascii files are provided.
- MESA inlists and resulting data for simulations carried out for the paper. A README file is included in the zip file with further information.
