This based on the theoretical correlations found by Heinzel, Gouttebroze, Vial (1994).

    S. Ueno 40 Years History of Spectroscopic Researches using Domeless Solar Telescope of Hida Observatory (1979 – 2018) In this year, just 40 years passed after the Domeless Solar Telescope (DST) was built at Hida Observatory in 1979. In this talk, I would like to look back on spectroscopic researches that have been performed in the past 40 years with classifying them by each observation object, as follows.

    Photosphere (Quiet Region)
    - Convection
    - Differential Rotation
    - Gravitational Redshift
    - Line Formation
