Magnetic Structure of Sunspots
In this review we give an overview about the current state-of-knowledge of the magnetic field in sunspots from an observational point of view. We start by offering a brief description of tools that are most commonly employed to infer the magnetic field in the solar atmosphere with emphasis in the photosphere of sunspots. We then address separately the global and local magnetic structure of suns...
متن کاملSunspots in the Laboratory
We show that extrinsic or non-fundamental uncertainty influences markets in a controlled environment. This work provides the first direct evidence of sunspot equilibria. These equilibria require a common understanding of the semantics of the sunspot variable, and they appear to be sensitive to the flow of information. Extrinsic uncertainty matters when information flows slowly, as in a call mar...
متن کاملOn the origin of sunspots
It is proposed that sunspots (and other flux emergence phenomena) originate due to the presence of fluctuating magnetic fields in addition to the regular, mean field in the convection zone. The mean field predicted by dynamo theories is too weak by itself to emerge at the surface of the Sun. However, the same dynamoprocesses that produce themeanfield also produce fluctuating fields. It is sugge...
متن کاملSunspots and Temperatures
Power spectrum analyses of temperature series at New York City (1822-1956), the Netherlands (1735-1944), and central England (1698-1955) show that the only significant energy in these spectrums appears at the annual period of 12 months. No significant energy was found corresponding to any known sunspot periodicity. Correlation coefficients between January and July temperatures for the years of ...
متن کاملSimulations of waves in sunspots
Magnetic field modifies the properties of waves in a complex way. Significant advances has been made recently in our understanding of the physics of waves in solar active regions with the help of analytical theories, numerical simulations, as well as hi-resolution observations. In this contribution we review the current ideas in the field, with the emphasis on theoretical models of waves in sun...
