Magnetized disk models lower the thermal-viscous instability threshold to Eddington ratios of 0.01-0.03 and yield limit-cycle timescales of months to years, jointly matching observations in five CLAGN only when the inner disk is strongly magnetized.

Spectral fitting of 2022 observations indicates the disk reaches 7-17 R_g from the neutron star at low inclination, with first reported type-II bursts attributed to magnetospheric gating.
Requiring thermal stability and single-valuedness in the thin-disk Ṁ-Σ plane produces a viscosity law α(X) with X = P_gas/P_rad that eliminates the radiation-pressure dominated instability while preserving the effective-temperature profile.
HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.
Multi-wavelength data from SDSS J1430+2303 are interpreted as evidence that radiation pressure instabilities drive a shrinking unstable accretion-disk zone, based on timing analysis, weak soft excess, and SED-derived black-hole parameters.
Black hole spin constraints for Cyg X-1 from XRISM Resolve data are strongly model-dependent, ranging from a*~0.99 with relxill to a*~0 with relxillCp or reflkerrD.

A magnetically-supported disk-corona model for Changing-Look AGN transitions
Magnetized disk models lower the thermal-viscous instability threshold to Eddington ratios of 0.01-0.03 and yield limit-cycle timescales of months to years, jointly matching observations in five CLAGN only when the inner disk is strongly magnetized.

On the assessment of the disk truncation and detection of type-II bursts from the accreting millisecond X-ray Pulsar IGR J17062-6143
Spectral fitting of 2022 observations indicates the disk reaches 7-17 R_g from the neutron star at low inclination, with first reported type-II bursts attributed to magnetospheric gating.

Radiation-pressure instability is an artifact of constant-$\alpha$ closure
Requiring thermal stability and single-valuedness in the thin-disk Ṁ-Σ plane produces a viscosity law α(X) with X = P_gas/P_rad that eliminates the radiation-pressure dominated instability while preserving the effective-temperature profile.

Model dependence of XRISM black-hole spin constraints in Cyg X-1
Black hole spin constraints for Cyg X-1 from XRISM Resolve data are strongly model-dependent, ranging from a*~0.99 with relxill to a*~0 with relxillCp or reflkerrD.
