Sadly the progenitor star name (number) & vital statistics are not listed.
The picture of tycho's supernova remnant also raises another question. As the !a supernova is a binary with the WD having gone "pop", the companion should also still be present and be within the confines of the expanding shell.
Finding the other half of the progenitor of a type 1a supernova would also be interesting, and should be a giant (or subgiant with its outer layers stripped by accretion onto the WD or blast wave ram...) enriched in Fe and a fair quantity of pre Fe transition metals.
have a nice day: Ag
