    Effect of partial ionization on wave propagation in solar magnetic flux tubes
    Observations show that waves are ubiquitous in the solar atmosphere and may play an important role for plasma heating. The study of waves in the solar corona is...

    Elusive Magnetic Structures in the Sun and Solar-Type Stars
    The magnetic structures of the Sun are very inhomogeneous, with irregularities smaller than the smallest sizes that we resolve from Earth. Such irregularities...

    Emergence of magnetic flux sheets in the quiet Sun: I. Statistical properties
    Context. Small-scale magnetic flux emergence in the quiet Sun is crucial for maintaining solar magnetic activity. On the smallest scales studied so far, namely...

    Emergence of magnetThe limits of the thin flux tube approximation
    The studies of the emergence of magnetic flux across the convection zone show how the individual magnetic tubes rise toward the surface at the same time...

    Emergence of Small-Scale Magnetic Loops in the Quiet-Sun Internetwork
    We study the emergence of magnetic flux at very small spatial scales (less than 2") in the quiet-Sun internetwork. To this aim, a time series of...
