HST Observations of X-Ray Transients
  Results from an HST/multiwavelength campaign on the 1996 outburst of GRO J1655-40 are reported. We find evidence for an approximately isothermal outer disk in GRO J1655-40 during the decline from outburst, possibly indicating the outer disk being maintained in the hot state. HST observations of GRO J0422+32 made 2 years after outburst reveal a sharply peaked optical/near UV spectrum, providing strong evidence for non-thermal emission.
