Near infrared maps of the planetary nebula IC 418 taken at 5 arc sec spatial resolution are presented. These show an extremely compact source structure at 1.65...

Sunspots are the most spectacular manifestation of solar magnetism, yet 99% of the solar surface remains "quiet" at any time of the solar cycle. The quiet sun...

We present the results of long-slit spectroscopy, in several positions, of the Orion Nebula. Our goal is to study the spatial distributions of a large number of...

We investigate the clustering and dynamics of nano-sized particles (nano dust) in high-resolution (1024 3) simulations of compressible isothermal hydrodynamic...

We present recent observations of quiet regions near the center of the solar disk using the Advanced Stokes Polarimeter. These observations reveal a component...

Context. Light bridges are convective intrusions in sunspots that often show enhanced chromospheric activity. Aims: We seek to determine the nature of flux...

Small bipolar magnetic features are observed to appear in the interior of individual granules in the quiet Sun, signaling the emergence of tiny magnetic loops...

Context. Advancements in instrumentation have revealed a multitude of small-scale extreme-ultraviolet (EUV) events in the solar atmosphere and considerable...

We present the results of long-slit spectroscopy in several slit positions that cover different morphological structures of the central parts of three bright...
