Missing Titanium in the Asymmetric Supernova Remnant W 49B

The progenitor of the W 49B supernova remnant is still under debate. One of the candidates is a jet-driven core-collapse supernova. In such a highly asymmetric explosion, a strong α -rich freeze-out is expected in local high-entropy regions, which should enrich elements synthesized by the capture of...
