Kiepenheuer Institute for Solar Physics

The Kiepenheuer Institute for Solar Physics (KIS) conducts experimental and theoretical investigations of physical processes on and within the Sun. Its headquarter is in Freiburg, Germany. The KIS operates the german solar telescopes at Teide Observatory on Tenerife (Spain) where most of the scientific observations are performed. KIS offers lectures on astronomy and astrophysics at Freiburg university and trains young scientists.

Picture of the Month

The magnetic phenomena on the solar and stellar surfaces are driven by the interior dynamo of the star, which generates strong magnetic fields in the form of spots in the stellar photosphere.
The solar photosphere has been intensely studied in the past years using atomic lines, but to shed light on the darkest and coolest parts of sunspots and starspots, the use of molecular lines is favorable because atomic lines receive a strong contribution from outside the spot umbra, whereas some molecular lines can only be formed in cool spots if the effective temperature of the stellar photosphere is high enough. The choice of the adequate molecule therefore represents the key to measuring magnetic fields unambiguously in unresolved spots wherein the molecules are formed. In addition, molecules exhibit high temperature, pressure, and magnetic field sensitivities and provide a unique tool to study physical properties of cool objects and particularly their magnetic fields through phenomena such as...
