Our group continues to obtain coronagraphic observations of disks around young stars with the STIS and ACS instruments on HST. Previously unknown highly structured disks and jets have been discovered, and some of the disks show "clearings", possibly due to planets. Spectroscopy of these stellar disks has also been obtained. The coronagraphic images and spectra are used to constrain models of the formation and evolution of the disks and the formation of possible planets.
