Cím: Small scale solar magnetic fields as seen by MBPs: Results obtained 
during my PHD and further beyond

Kivonat:
In this talk we will give a short insight into the basics of the Sun and 
then concentrate on small scale solar magnetic fields. It is well known 
that the dynamics and the activity of the solar atmosphere is due to 
magnetic fields and their interaction with the plasma. The global magnetic 
field of the Sun is generated by a solar dynamo believed to be localised 
in the tachoclyne. This global dynamo gives rise to the global activity 
and the solar activity cycle. But magnetic fields are not restricted only 
to huge scales and huge field strengths but span down to the smallest and 
weakest elements. In this talk we concentrate on small scale elements with 
strong magnetic field strengths. These elements can be identified in 
filtergrams taken in special filters like the G-band, as so called 
Magnetic Bright Points (MBPs). We will give an overview about the 
motivation factors why to investigate these structures and then discuss in 
more details the new insights gained during the lecturer's PHD thesis 
work.
