abstract

We explore the long-term evolution of mass-transferring white dwarf binaries undergoing both direct-impact and disk accretion and explore implications of such systems to gravitational wave astronomy. We cover a broad range of initial component masses and show that these systems, the majority of which lie within the LISA sensitivity range, exhibit prominent negative orbital frequency evolution (chirp) for a significant fraction of their lifetimes. Using a galactic population synthesis, we predict ~$2700$ double white dwarfs will be observable by LISA with negative chirps less than $-0.1\ yr^{-2}$. We also show that detections of mass-transferring double white dwarf systems by LISA may provide astronomers with unique ways of probing the physics governing close compact object binaries.

  1. Gravitational Wave Modeling of White-Dwarf--Compact-Object Binaries and Observational Outlook

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    WD–CO binaries produce unique GW waveforms with a sharp f_max cutoff; LGWA/DECIGO will detect many end stages, while terrestrial detectors will not mistake them for sub-solar compact objects.

  2. Detecting White Dwarf Binary Mergers with Gravitational Waves

    gr-qc 2025-10 conditional novelty 6.0 of 10

    MAGIS Space and AEDGE could detect white-dwarf-binary mergers in the 10 mHz–1 Hz band, giving early warning of Type Ia supernova explosions at rates of roughly one every four years and a few hundred per year, respectively.

  3. Astrophysics and cosmology with a decihertz gravitational-wave detector: TianGO

    gr-qc 2019-08 conditional novelty 6.0 of 10

    A decihertz space gravitational-wave detector paired with a ground network would localize compact binary mergers far more precisely than the ground network alone, supporting standard-siren cosmology, early warning, an...

  4. The Missing Link in Gravitational-Wave Astronomy: Discoveries waiting in the decihertz range

    gr-qc 2019-08 accept novelty 3.0 of 10

    A Decihertz Observatory would fill the gap between LISA and ground detectors, enabling early-warning multimessenger astronomy and measurements of intermediate-mass black hole populations.

  5. Population Synthesis of Gravitational Wave Sources

    astro-ph.HE 2025-02 accept novelty 1.0 of 10

    A review of population synthesis: the codes, the environments, and the predicted rates and features of gravitational wave sources, with an emphasis on breaking degeneracies.
