The exploration of MHD disk winds in the RU Lup disk

SEONGJOONG KIM, Hideko Nomura, Xuening Bai

The magnetohydrodynamic (MHD) disk wind is one of the mechanisms to transport the angular momentum of disk materials in protoplanetary disks. Although high-velocity winds/outflows/jets are easily observed at the optical regime, low-velocity winds are rarely detected. In this study, we investigate how to detect the MHD winds with CO and CN emission lines in mm-wavelengths by ALMA. We briefly introduce our ALMA observation of the RU Lup disk and describe a pipeline to examine the MHD wind signature hidden in the line spectra by comparing our data with a simple parameterized disk wind model.
