摘要：

We present high-contrast observations of 68 young stellar objects (YSOs) that have been explored as part of the Strategic Exploration of Exoplanets and Disks with Subaru (SEEDS) survey on the Subaru telescope. Our targets are very young (<10Myr) stars, which often harbor protoplanetary disks where planets may be forming. We achieve a typical contrast of similar to 10(-4)-10(-5.5) at an angular distance of 1" from the central star, corresponding to typical mass sensitivities (assuming hot-start evolutionary models) of similar to 10 M-J at 70 au and similar to 6 M-J at 140 au. We detected a new stellar companion to HIP 79462 and confirmed the substellar objects GQ Lup b and ROXs 42B b. An additional six companion candidates await follow-up observations to check for common proper motion. Our SEEDS YSO observations probe the population of planets and brown dwarfs at the very youngest ages; these may be compared to the results of surveys targeting somewhat older stars. Our sample and the associated observational results will help enable detailed statistical analyses of giant planet formation.
