Leibniz Institute for Solar Physics

The Institute for Solar Physics, German Institut fur Sonnenphysik and abbreviated KIS, is a non-university research institute located in Freiburg, Germany. It was formerly known as the Kiepenheuer Institute for Solar Physics, and from 2018 to 2023 it carried the name Leibniz Institute for Solar Physics. The institute conducts application-oriented basic research in astronomy, astrophysics and solar physics. In July 2023 the Leibniz Association Senate recommended ending joint federal and state funding, and KIS lost its Leibniz membership at the end of 2023. It then entered a wind-down phase with transitional funding secured until 31 December 2026.
