Planet Formation: the Direct Approach While thousands of exoplanets have been confirmed over the past 20 years, allowing for valuable inferences about the formation process, only a handful of candidate exoplanets with ages commensurate with the epoch of planet formation are known. We are thus left with only a general picture and a set of broad processes and time lines but little concrete data. Kepler in particular has taught us that exoplanets are common; therefore they must be fairly easy to form. However, we do not know _how_ easy exoplanets are to form, whether all, one in two, or one in ten survive, nor where/when the formation process takes place. Furthermore, it is unclear how the answers to these questions weigh on the probability of formation of habitable planets. Given the challenging nature of young star observations, i.e. relatively large distances, accretion, extreme stellar activity, obscured location in molecular clouds, massive planets provide the easiest access to the direct study of planet formation. In addition, the presence or absence of giant planets / hot Jupiters may have a profound impact on the prospects for Earth-like / habitable planets generally. I will review recent young candidate planet identifications, describe the optical and infrared surveys undertaken by my colleagues and I with the 2dCoude and IGRINS at McDonald Observatory, and more recently IGRINS at the DCT, and discuss prospects for significant future advances in the field.
