Model of the Her X-1 system showing the twisted and tilted disk. Yellow is coolest and blue is hottest. Boroson 2000.
RXTE/ASM lightcurves of Her X-1. Thin blue arrows designate various x-ray observation times (ASCA, BeppoSax, Suzaku or XMM). Green arrows designate EUVE observation times. Cyan arrows designate ISO observation times. Yellow and magenta arrows designate Spitzer XRT and UVOT observation times. Black arrows designate unidentified observation times.
