The origin and dynamic interaction of solar magnetic fields
The dynamics of the solar corona are dominated by the magnetic field which creates its structure. The magnetic field in most of the corona is ?frozen? to the plasma very effectively. The exception is in small localised regions of intense current concentrations where the magnetic field can slip …

A near-infrared filter system and study of solar umbral dots at 1.6 µm
The observations of solar magnetic fields are very important because they influence events on the sun. Almost all of magnetographs in the world work in the visible wavelength and they are powerful instruments for measuring strong magnetic fields (above 1000 Gauss) on the sun. To measure the weak …

Comparing Different Methods for Estimating Total Open Heliospheric Magnetic Flux
<p>There are extended periods over the solar cycle where significant discrepancies occur between the observed open magnetic flux (i.e., those based on spacecraft observations) and that determined from coronal models. One explanation for the source of these discrepancies is the magnetic fields in …

Development of advanced algorithms to detect, characterize and forecast solar activities
Study of the solar activity is an important part of space weather research. It is facing serious challenges because of large data volume, which requires application of state-of-the-art machine learning and computer vision techniques. This dissertation targets at two essential aspects in space …
