Is there a name for the star/supernova hypothesized to have been a precursor to the Solar System?
I couldn't find a name for this hypothetical star/nova after some research.


First off, the existence of this former object is hypothetical. Others working in this field have different hypotheses / conjectures; the science is far from settled. Secondly, if true, this star formed a supernova at the time the solar system was born and hence it no longer exists as a star. Thirdly, what's the point? Naming this hypothetical object would add zero credence to the hypothesis, and arguably would detract as being a bit premature.
