On the size distribution of sunspot groups in the Greenwich sunspot record 1874-1976

I. Baumann, S. K. Solanki

We investigate the size distribution of the maximum areas and the instantaneous distribution of areas of sunspot groups using the Greenwich sunspot group record spanning the interv…

A necessary extension of the surface flux transport model

I. Baumann, D. Schmitt, M. Schuessler

Customary two-dimensional flux transport models for the evolution of the magnetic field at the solar surface do not account for the radial structure and the volume diffusion of the…

Pressure dependence of the Mg $3 s 4 s^{3} S_{1} \to 3 s 3 p^{3} P_{0, 1, 2}$ transition in superfluid $^{4}$ He

I. Baumann, A. Breidenassel, C. Zühlke +4

The pressure shifts of the $3 s 4 s^{3} S_{1} \to 3 s 3 p^{3} P_{0, 1, 2}$ transition of magnesium atoms immersed in superfluid helium have been measured at $(1.3 \pm 0.1)$ K between saturated vapou…
