"Emission line spectropolarimetry of low-mass young stellar objects"
National Astronomical Observatory of Japan
Low-mass young stellar objects show various optical emission lines
associated with mass inflow and outflow activities within the
circumstellar environment. These emission lines also possess linear
polarization, which gives us unique information on geometry and
kinematics of the circumstellar structure close to the central star.
We obtained high-dispersion linear polarization spectra of emission
lines of a few low-mass young stellar objects (T Tauri stars). The
echelle spectropolarimeter LIPS, developed by our team, was used on
the UH 2.2-m telescope at Mauna Kea. We show observed results and
discuss the circumstellar structure of T Tauri stars based on
the measured polarization.
