    Magnetic bright points in the quiet Sun
    We present a visual determination of the number of bright points (BPs) existing in the quiet Sun, which are structures though to trace intense kG magnetic...

    Magnetic Field Information in the Near-ultraviolet Fe II Lines of the CLASP2 Space Experiment
    We investigate theoretically the circular polarization signals induced by the Zeeman effect in the Fe II lines of the 279.3-280.7 nm spectral range of the...

    Mapping the Hidden Magnetic Field of the Quiet Sun
    The Sun is the only star where we can resolve the intricate magnetism that all convective stars harbor. Yet, more than 99% of its visible surface along the...

    Multiline Stokes Synthesis of Ellerman Bombs: Obtaining Seamless Information from Photosphere to Chromosphere
    Magnetic reconnection in the lower atmosphere is a critical process in determining the chromospheric dynamics, such as Ellerman bombs and UV bursts. Because the...

    Observation and Modeling of the Circular Polarization of the Cr I Magnetic-field-induced Transition at 533.03 nm
    We study the circular polarization of the magnetic-field-induced transition (MIT) between the 3d 5( 6 S)4d 7 D 2 and 3d 5( 6 S)4p 7 P 4° states of Cr I at 533...

    Response of the solar atmosphere to the photospheric plasma motion
    The dynamics of the solar atmosphere is largely controlled by its magnetic coupling to the photosphere of the Sun. Since the solar magnetic field is complex...

    SOLAR COMPOSITION AS A REFERENCE FOR STARS
    The solar abundance of chemical elements play an important role in addressing such important issues as the formation, structure, and evolution of the Sun and...

    The Magnetic Nature of Our Sun
    This talk will give an overview of our understanding of the Sun in the 1960's, the major discoveries since then, and the main questions that need to be answered...
