Aryabhatta Research Institute
Situated adjacent to the picturesque hill town of Nainital, ARIES ( an acronym of Aryabhatta Research Institute of observational sciencES ) is one of the leading research Institutes which specializes in observational Astronomy & Astrophysics and Atmospheric Sciences. The main research interests of Astronomy & Astrophysics division are in solar, planetary, stellar, galactic and extra-galactic astronomy including stellar variabilities, X-ray binaries, star clusters, nearby galaxies, quasars, and inherently transient events like supernovae and highly energetic gammaray bursts.Research focus in Atmospheric Sciences division is mainly in the lower part of the atmosphere and covers the studies on aerosols and trace gases.Moreover, to strengthen the scientific contribution.
The Institute hosts two telescopes of apertures 56-cm and 104-cm. There are two 15-cm telescopes dedicated for solar observations. The 104-cm optical telescope is being used as a main observing facility by the ARIES scientists since 1972. It is equipped with 2k x 2k, and 1k x 1k liquid N cooled CCD cameras, fast photometer, spectrophotometer, and standard astronomical 2 filters. The telescope uses a SBIG ST-4 camera for auto-guiding through an auxiliary 20-cm telescope.
