The instrument called TANSPEC, will provide unique medium resolution (R ~ 2000) spectroscopy capability to the telescope in a broad waveband range of 0.8 to 2.5 microns. It will also have low resolution prism mode (R~200) and a slit viewer with field of view of 1 x 1 arcmin square. This instrument will be extremely sensitive to low temperature stellar photospheres (T · 2500 K) and objects surrounded by warm dust envelopes or embedded in dust/molecular clouds. It is therefore particularly suited to the study of low and very low mass stellar populations (M/Ldwarfs, brown dwarfs), strong mass-losing stars on the asymptotic giant branch (AGB), young stellar objects (YSOs) still in their proto-stellar envelopes and active galactic nuclei (AGN). In this talk, I will discuss about the specification and science goal of this instrument along with some recent updates. |
