We present monitoring observations of the active T Tauri star RW Aur, from 2010 October to 2015 January, using
optical high-resolution (R 10,000) spectroscopy with Canada–France–Hawaii Telescope/ESPaDOnS. Optical
photometry in the literature shows bright, stable fluxes over most of this period, with lower fluxes (by 2–3 mag) in
2010 and 2014. In the bright period our spectra show clear photospheric absorption, complicated variation in the
Ca II λ8542 emission profile shapes, and a large...[Show more]
