dc.description.abstractThe detection and characterization of planets around young stars presents a direct window into some of the most transformative and poorly understood processes of planet evolution, such as formation mechanisms, disk migration, and (perhaps) gap formation. Radial velocity detections can be particularly powerful for a number of reasons, not least of which is their ability to directly constrain planet masses and eccentricities. Yet despite RV analysis’ prolific track record when applied to main sequence stars, employing it to search for planets around young stars has proven exceptionally difficult because of stellar activity. This thesis is dedicated to the development and application of multiwavelength tools for RV planet searches as well as to enlarging the sample of young stars suitable for such searches. It presents work that forwards these causes in three ways: first, by presenting three software pipelines that measure RVs from reduced spectra taken with three different instruments; second, by validating a sample of young stars through follow-up spectroscopy and photometry; and third, by performing a multiwavelength RV planet search of several accreting and non-accreting T-Tauri stars.
