Monitoring Hard-Tails of LMC X-3 and LMC X-1
Abstract
LMC X-3 and LMC X-1 are fiducial black hole candidates and both are always in the 'soft' spectral state. They often exhibit hard-tails above 10 keV besides the soft optically-thick disk spectra. GINGA satelli te observed the two sources several times, and the hard-tail componets were found to be variable, and the variation seemed independent of the soft component. However, GINGA observations were sparse and irregular, not enough to precisely quantify the relat ion of the two components. We propose to monitor the two sources regularly and frequently with the XTE PCA, in order to clarify the relationship of the two components. Our model predicts the soft component lags behind the hard component by several t ens of days.
