The system contains a white dwarf accretor, which likely originated as a post–common envelope carbon–oxygen (CO) white dwarf, and a warm donor (Teff,donor = 16,400 ± 1000 K). The donor probably formed during a common envelope phase between the CO white dwarf and an evolving giant that left behind a helium star or white dwarf in a close orbit with the CO white dwarf. We measure gravitational wave–driven orbital inspiral with ∼51σ significance, which yields a joint constraint on the component masses and mass transfer rate. While the accretion disk in the system is dominated by ionized helium emission, the donor exhibits a mixture of hydrogen and helium absorption lines. Phase-resolved spectroscopy yields a donor radial velocity semiamplitude of 771 ± 27 km s−1, and high-speed photometry reveals that the system is eclipsing. We detect a Chandra X-ray counterpart with LX ∼ 3 × 1031 erg s−1. Depending on the mass transfer rate, the system will likely either evolve into a stably mass-transferring helium cataclysmic variable, merge to become an R CrB star, or explode as a Type Ia supernova in the next million years. We predict that the Laser Space Interferometer Antenna (LISA) will detect the source with a signal-to-noise ratio of 24 ± 6 after 4 yr of observations. The system is the first LISA-loud mass-transferring binary with an intrinsically luminous donor, a class of sources that provide the opportunity to leverage the synergy between optical and infrared time domain surveys, X-ray facilities, and gravitational-wave observatories to probe general relativity, accretion physics, and binary evolution."}],"oa":1,"year":"2023","author":[{"last_name":"Burdge","first_name":"Kevin B.","full_name":"Burdge, Kevin B."},{"full_name":"El-Badry, Kareem","last_name":"El-Badry","first_name":"Kareem"},{"full_name":"Rappaport, Saul","last_name":"Rappaport","first_name":"Saul"},{"first_name":"Tin Long","last_name":"Sunny Wong","full_name":"Sunny Wong, Tin Long"},{"last_name":"Bauer","first_name":"Evan B.","full_name":"Bauer, Evan B."},{"full_name":"Bildsten, Lars","first_name":"Lars","last_name":"Bildsten"},{"full_name":"Caiazzo, Ilaria","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria","last_name":"Caiazzo","orcid":"0000-0002-4770-5388"},{"last_name":"Chakrabarty","first_name":"Deepto","full_name":"Chakrabarty, Deepto"},{"last_name":"Chickles","first_name":"Emma","full_name":"Chickles, Emma"},{"last_name":"Graham","first_name":"Matthew J.","full_name":"Graham, Matthew J."},{"full_name":"Kara, Erin","first_name":"Erin","last_name":"Kara"},{"full_name":"Kulkarni, S.
