Abstract / Description of output
Simultaneous observations of SS433 at IR and visible wavelengths are
reported. Three pronounced features are established: (1) an enormous
apparent excess of IR over optical flux; (2) an almost flat spectrum for
wavelengths greater than 1.2 microns; and (3) a variation of IR and
optical flux together on a time scale of several days. The IR excess is
attributed to a region of gas that radiates by free-free and free-bound
emission processes with a total emission measure of the order of 10 to
the 61st per cu cm.
