Infrared lines as probes of solar magnetic features. IV: The thermal-magnetic relation and Wilson depression of a simple sunspot

摘要: We analyse the relationship between temperature and magnetic vector, as derived from 1.56 μm spectra, in a simple sunspot. Due to high Zeeman sensitivity of g=3, line, we can study this throughout confirm field-strength, B, vs, temperature, T, found by Kopp & Rabin (1992). In addition, also find linear relation inclination angle, γ', T. An analysis based on assumption magnetohydrostatic force balance gives an estimate Wilson depression, Z W , Our supports jump 200-500 km at umbral boundary agrees with relatively constant penumbra
