II.3 S-curves of Local Disk Solutions~ L Eddstandard solutionswithout magnetic fieldS-curves with different values ofΦ 1= B ϕHOur model may help raise the critical accretion rate (or luminosity)for the thermal instability, which may be consistent with theobserved X-ray sources with high luminosities.11
III. Summary• By assuming that the field responds negatively to a positivetemperature perturbation, we find that the critical massaccretion rate increases significantly. This accounts for thestability of the observed sources with high luminosities.• Our model also presents a possible explanation as to why onlyGRS 1915+105 seems to show thermally unstable behavior.This peculiar source holds the highest accretion rate (orluminosity) among the known high state sources.12
