Black hole X-ray transients: Results from recent multiwavelength observations
We report preliminary results from multi-wavelength multiepoch observations of XTEJ1859+226 and XTEJ1118+480. The outburst lightcurves and IR-optical-UV spectra of XTEJ1859+226 suggest an irradiation-prolonged thermal-viscous disc instability model for the outburst. XTEJ1859+226 probably has P-orb l...

| description | We report preliminary results from multi-wavelength multiepoch observations of XTEJ1859+226 and XTEJ1118+480. The outburst lightcurves and IR-optical-UV spectra of XTEJ1859+226 suggest an irradiation-prolonged thermal-viscous disc instability model for the outburst. XTEJ1859+226 probably has P-orb less than or similar to 1d. XTEJ1118+480 has P-orb approximate to 4.1hr and was observed in an unusual 'low-hard state' outburst. It exhibits variability on timescales similar to 10s at wavelengths ranging from infrared to X-ray. The accreting material in XTEJ1118+480 has been CNO processed; we discuss implications for the prior evolution of this unusual binary. |
