20.500.12556/RUL-153043 Meritve temperature Sončevih peg magistrsko delo Sunspots Temperature Measurements Sonce je nam najbližja zvezda. Na Soncu se v vidni svetlobi med povečano magnetno aktivnostjo pojavijo številne Sončeve pege, ki so posledica motenj v Sončevem magnetnem polju. V nalogi smo se osredotočili na merjenje temperature Sončevih peg. V ta namen smo Sonce fotografirali več dni zapored s pomočjo preproste opreme: 20-cm Newtonovega teleskopa, steklenega filtra Thousand Oaks in digitalnega fotoaparata Canon EOS 700D. Posnetke smo obdelali in analizirali, povezali intenziteto svetlobe s funkcijo izvira in s Planckovo funkcijo ter izračunali temperaturo Sončevih peg. Na koncu smo primerjali še temperaturni profil peg pri valovni dolžini 500 nm s semiempiričnimi modeli. V magistrski nalogi smo pokazali, da je temperaturo Sončevih peg mogoče oceniti že z uporabo preproste šolske opreme. The Sun is our nearest star. On the Sun, many Sunspots appear in visible light during increased magnetic activity, which are the result of disturbances in the Sun's magnetic field. In this thesis, we focus on measuring the temperature of sunspots. To do this, we photographed the Sun on several consecutive days using simple equipment: a 20-cm Newtonian telescope, a Thousand Oaks glass filter and a Canon EOS 700D digital camera. We processed and analysed the images, connected the intensity of the light with the source function and the Planck function, and calculated the temperature of the sunspots. At the end, we compared the temperature profile of the sunspots at 500 nm with semiempirical models. In this MSc thesis, we have shown that the temperature of sunspots can be estimated even with simple school equipment.
