We have analyzed the X-ray spectra of the microquasar GRS 1915+105, as observed with the PCA on the Rossi XTE, during periods of stable weak emission, outbursts and rapid flaring. We find that the complicated X-ray intensity curve of this source can be described by the rapid removal and replenishment of matter forming the inner part of an optically thick accretion disk, probably caused by a thermal-viscous instability analogous to that operating in dwarf novae, but here driven by the Lightman-Eardley instability. We find that the mass accretion rate in quiescence is 10^-6 solar masses per year. Only a small fraction of the energy liberated by accretion is emitted as radiation. We suggest that most of this energy is advected into the black hole in the high-viscosity state of the outburst cycle.

  1. Distinct Jet Properties in the X-Ray-Obscured State of GRS 1915+105

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

    VLBI observations during 2025 radio flares find no detectable jet motion in GRS 1915+105, implying its obscured-state jets are slower (βΓ≲0.40) than the pre-2019 relativistic jets.

  2. An atypical X-ray variability component in the black hole candidate AT2019wey

    astro-ph.HE 2026-06 unverdicted novelty 5.0 of 10

    Detection of an imaginary QPO in AT2019wey whose frequency drops from ~5 Hz to ~1 Hz with rising phase lags as the source transitions through HIMS and LHS, showing U-shaped phase-lag spectrum in HIMS.

  3. A 0.03 Hz Radio Quasi-periodic Oscillation During the 2025 Flare of GRS 1915+105

    astro-ph.HE 2026-06 unverdicted novelty 4.0 of 10

    A recurring 0.03 Hz radio QPO was detected in the 2025 flare of GRS 1915+105 at >5.9 sigma in one epoch, identical across S- and X-bands and prior years, indicating an intrinsic accretion-jet timescale.
