Partner Groups

Partner Groups

Partner Groups can be established in cooperation with an institute abroad if an outstanding junior scientist (postdoc) returns after a research visit to a Max Planck Institute to a well-equipped high-capacity laboratory in his home country and continues his research on a research topic that is also of interest to the previous host Max Planck Institute.

Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune (India)

Head of the Partner Group: Professor Durgesh Tripathi

The main scientific objective of this collaboration is to study the dynamics and coupling of the solar atmosphere with emphasis on eruptive phenomena on the Sun, heating of the upper solar atmosphere i.e., corona and chromosphere, and sun-climate relationship. The problem of solar coronal and chromospheric heating has been at the forefront of astrophysics research since its discovery in 1940s. Despite major improvements in theoretical modelling and observational capabilities, the solution remains illusive. Additionally, large-scale solar eruptions such as solar flares and coronal mass ejections have direct consequences and potentially devastative impact on space weather and geo-space climate. The occurrence of these highly energetic phenomena has proven to be highly difficult to comprehend. In addition, the UV, EUV and X-ray radiation from the Sun play an important role in shaping our longer-term climate pattern on Earth. In particular the UV radiation from the Sun is of prime importance as it heats the Earth’s Stratosphere and Mesosphere, regulating Ozone abundance and influencing dynamics of Earth’s climate.

In the Sun and Sun-like stars, thermal convection likely drives large-scale flows, differential rotation and meridional circulation, which in turn generate and sustain global magnetic fields (dynamo). However, modeling convection is one of the greatest challenges in stellar physics. This collaboration aims to measure convective velocities in the solar interior using improved techniques of helioseismology applied to Solar Dynamics Observatory observations (hosted at MPI for Solar System Research), to discriminate among competing theories and elucidate global dynamics in stellar convection zones.
