Detección y análisis de pequeñas estructuras magnéticas en las regiones próximas a los polos solares
Abstract
The solar magnetic field plays a fundamental role in the overall behaviour of the Sun. In the solar photosphere, the magnetic field is evidenced with a wide range of structures with different sizes, shapes and intensities. Bright Points (BPs) are the smallest of these manifestations discernible with the current instruments, and their presence is observable all over the solar disk, on both active and quiet regions. However, due to difficulties in observing polar areas, the presence of BPs in these regions is poorly known so far. The Solar Orbiter mission will be launched in 2018 and will observe the Sun up to 30º outside the ecliptic, allowing the analysis of BPs appearance in areas close to the solar poles. A preliminar study can be done considering the inclination of the ecliptic plane relative to the solar axis, so that these regions can be observed at certain times in the year. In this work, G-band images have been used to detect and analyse BPs located in areas close to the solar poles.
