    Deciphering Solar Coronal Heating: Energizing Small-scale Loops through Surface Convection
    The solar atmosphere is filled with clusters of hot small-scale loops commonly known as coronal bright points (CBPs). These ubiquitous structures stand out in...

    Design of an adaptable Stokes polarimeter for exploring chromospheric magnetism
    The chromosphere is a highly complex and dynamic layer of the Sun, that serves as a conduit for mass and energy supply between two, very distinct regions of the...

    Effects of Spectral Resolution on Simple Magnetic Field Diagnostics of the Mg II H and K Lines
    We study the effects of finite spectral resolution on the magnetic field values retrieved through the weak-field approximation (WFA) from the cores of the Mg II...

    Emergence of Internetwork Magnetic Fields through the Solar Atmosphere
    Internetwork (IN) magnetic fields are highly dynamic, short-lived magnetic structures that populate the interior of supergranular cells. Since they emerge all...

    Evaluating the Reliability of a Simple Method to Map the Magnetic Field Azimuth in the Solar Chromosphere
    The Zeeman effect is of limited utility for probing the magnetism of the quiet solar chromosphere. The Hanle effect in some spectral lines is sensitive to such...

    Formation of the Mg II h and k Polarization Profiles in a Solar Plage Model and Their Suitability to Infer Magnetic Fields
    The Mg II h and k lines are among the strongest in the near-ultraviolet solar spectrum and their line core originates in the upper chromosphere, just below the...
