A New LISA-detectable Type Ia Supernova Progenitor in the Southern Sky: SMSS J1138−5139
We present the discovery and analysis of a nearby eclipsing ultracompact accreting binary SMSS J1138−5139, the first well-constrained LISA-detectable Type Ia supernova progenitor. Our time-series optical spectroscopy identifies its orbital period through radial velocity monitoring at ${P}_{\mathrm{o...
