Abstract
Recent studies of sunspots have shown that there is a critical value (Bcrit) of the vertical component of the magnetic field (Bver) that triggers umbral mode of convection, i.e., only umbral convection is allowed in regions with Bver > Bcrit. We study the existence of a Bcrit in other magnetic structures, such as pores.
The evolution of magnetic properties on the pore boundary during its lifetime shows their role on the stability of pores.
