Towards a new view of the photospheric magnetic field with the Polarimetric and Helioseismic Imager on Solar Orbiter
(2024-12-19)Accurately determining the magnetic flux through the solar surface is incredibly important to understanding the dynamics of the Sun and its atmosphere. The magnetic field provides energy for heating the higher layers of ... -
High resolution scattering spectropolarimetry of the quiet solar photosphere
(2021-01-14)In this thesis we investigate small-scale scattering polarization signals in quiet, internetwork (IN) regions of the lower solar atmosphere. Small-scale polarization signals are inherently hard to observe due to their ... -
Slender Ca II H fibrils observed by SUNRISE/SuFI
(2018-04-24)This thesis is devoted to analyzing the morphological and oscillatory properties of slender \caiih{} fibrils (SCFs) in the lower solar chromosphere. The aim of this study is to deepen our understanding of the physical ... -
Analysis of historical solar observations and long-term changes in solar irradiance
(2017-10-25)The Sun is the main external driver of Earth's climate. Various mechanisms of the solar influence on climate have been proposed. The debate is ongoing, but variation in the radiative flux of the Sun is among the main ... -
Cycle-related solar vacuum ultraviolet (VUV) variability
(2015-11-09)Various studies has shown that the Sun was in an extremely inactive state during the prolonged minimum of the cycle 23 compared to other recent minima. Following these studies, in this thesis work, it was tried to have a ...
