    On the Formation of Lyman β and the O I 1027 and 1028 Å Spectral Lines
    We study the potential of Lyman β and the O I 1027 and 1028 Å spectral lines to help in understanding the properties of the chromosphere and transition region...

    On the Origin of the Type II Spicules: Dynamic Three-dimensional MHD Simulations
    Recent high temporal and spatial resolution observations of the chromosphere have forced the definition of a new type of spicule, "type II's," that are...
