Abstract

A high-resolution spectrograph for the 3.6-m Devasthal Optical Telescope (DOT) of Aryabhatta Reearch Institute of Observational Sciences (ARIES; Nainital, India) is envisaged to achieve the various science goals. The spectrograph will have two modes of spectral resolution (40 000 and 80 000) with a wavelength coverage of 380 - 900 nm. The design of the spectrograph will be similar to many contemporary high-resolution spectrometers in the world and will be based on a modern design using the white pupil concept. It will be a bench mounted fibre-fed spectrograph. In this article, we present the various science goals, technical specifications, and concept of design for the proposed spectrograph.
