Electromagnetic Characterization of the LISA Verification Binary ZTF J0526+5934
We present an analysis of new and archival data to the 20.506 minute LISA verification binary J052610.42+593445.32 (J0526+5934). Our joint spectroscopic and photometric analysis finds that the binary contains an unseen M _1 = 0.89 ± 0.11 M _⊙ CO-core white dwarf primary with an M _2 = 0.38 ± 0.07 M...

description | We present an analysis of new and archival data to the 20.506 minute LISA verification binary J052610.42+593445.32 (J0526+5934). Our joint spectroscopic and photometric analysis finds that the binary contains an unseen M _1 = 0.89 ± 0.11 M _⊙ CO-core white dwarf primary with an M _2 = 0.38 ± 0.07 M _⊙ post-core-burning subdwarf, or low-mass white dwarf, companion. Given the short orbital period and relatively large total binary mass, we find that LISA will detect this binary with signal-to-noise ratio 44 after 4 yr of observations. J0526+5934 is expected to merge within 1.8 ± 0.3 Myr and likely result in a D ^6 scenario Type Ia supernova or form a He-rich star that will evolve into a massive single white dwarf. |
