Part III Wednesday 15 July 14:20-14:35 TARdYS: Tao Aiuc high Resolution (d) Y-band Spectrograph (6.5 m TAO) Leonardo Vanzi (Pontificia UC, Chile) TARdYS (Tao Aiuc high Resolution (d) Y band Spectrograph) is an idea to equip the Tokyo Atacama Observatory TAO 6.5 meter telescope with an instrument able to measure precise radial velocities of cool stars. The project - a collaboration between the University of Tokyo and Catolica - aims to be a low-budget experiment to explore on a relatively short time scale the opportunity offered to high resolution spectroscopy in the near IR by an exceptional observing site.
