  bibo_abstract:
  - We investigate whether the nonaccreting phases found in thin, locally isothermal
    circumbinary disks survive when the disk thermodynamics are evolved self-consistently.
    We present grid-based hydrodynamics simulations of circumbinary accretion with
    an energy equation that includes viscous and hydrodynamic heating coupled to radiative
    blackbody cooling in the high-Mach number regime. We find that, although gas accumulates
    and heats at the far edge of the circumbinary cavity, the regions that launch
    accretion streams remain comparatively cold, leading to potentially long-lived
    suppression of the binary accretion rate as the large-scale feeding rate is reduced
    towards the Eddington limit. This runaway nonaccretion problem, however, is weakened
    relative to locally isothermal solutions. Despite their low accretion rates, binaries
    interacting with disks in a nonaccreting phase can remain sufficiently luminous
    and variable at optical and near-infrared frequencies to be detectable in upcoming
    wide-field surveys such as LSST and the Roman Space Telescope. Because of the
    effective truncation of the surrounding disk, though, such systems are comparatively
    faint in high energy, photoionizing emission, and may therefore appear as intrinsically
    X-ray–weak active galactic nuclei with weak or absent emission line features.
    We additionally suggest an update to grid-based sink prescriptions for approximating
    mass loss across an unresolved horizon when including an energy conservation equation.@eng
