摘要

We are conducting a multiwavelength radial velocity (RV) survey of the Taurus-Auriga low-mass star forming region. The goal of this survey is to characterize the hot Jupiter population around a sample of 1-3 Myr old classical and weak-lined T Tauri stars. Given the young ages of these targets, a positive detection will help identify the planet formation timescale. The presence of large, cool star spots makes this a challenging environment in which to conduct an RV survey. To distinguish between spot-induced RV variability and true companions, we observe all of our targets in both visible light and K band: spot-induced RV variability exhibits a wavelength dependence that companion-induced variability does not. We present details on our methodology and analysis of several planet candidate targets.
