. The spectrograph works at a resolution of 67000. With the help of simultaneous calibration technique, PARAS has achieved an RV accuracy of 1.3 m/s for the bright sun like quiet stars. Thorium-Argon lamp is used for calibration. New calibration techniques are also being explored by the project team. PARAS can detect planet in the

habitable zone In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.J. F. Kas ...
