Abstract

We present results from our survey for giant exoplanets around nearby A stars using the MMTO 6.5m telescope.

Motivated by the radial velocity detections of giant planets around evolved A stars, we selected A stars visible from the MMTO that are within 25 parsecs. The combination of a deformable secondary mirror AO system and the 3 to 5 micron Clio imaging camera allow us to reach model dependent sensitivities of a few Jupiter masses.

We present the direct imaging results of our survey, and coronagraphic observations of several brighter targets.
