Planetary Sciences

Chairman: Prof. S. A. Haider

Overview:

Our research programmes involve the applications of stable and radioactive isotopes to characterize and determine time scales of processes occurring in the early solar system. The aim is to study the origin and evolution of the solar system with focus on inner planets. We also aim to understand physical and chemical processes of planetary atmopsheres using observations, theoretical simulations and modelling of planetary atmospheres (Earth & Mars) and comets. The division is also running the Planetary Science and Exploration Programme (PLANEX, Co-ordinator: Dr. D. Banerjee)


Research Programmes:

  1. Petrographic, chemical and isotopic studies of Meteorites to understand cosmic ray exposure and evolutionary history
  2. Solar X-ray and fluorescence emission from Lunar Surface
  3. Reflectance Spectroscopy of Terrestrial and Lunar samples
  4. Isotope cosmochemistry and early solar system processes
  5. Study of presolar grains to understand various nucleosynthetic processes and stellar evolution
  6. Galactic chemical evolution
  7. Observations and modeling of trace gases, ions and dust, in the lower atmosphere of Mars
  8. Energetics, optical and X-ray emissions and dynamics of planetary ionospheres with emphasis on interaction of solar wind and EUV radiation with planetary and cometary atmospheres
  9. PLANEX (Planetary Science and Exploration Programme) : Develop payloads for planetary misions, Establishment of National facilities for research in planetary sciences, encourage research projects related to planetary sciences at universities and institutes in India.
