We conducted two multi-site campaigns for two previously poorly-studied rapidly oscillating Ap (roAp) stars, HD122970 and HD99563. In January-June 1998, we...

We have explored late-type spiral galaxies with truncated radial surface brightness profiles. Based on the study of optical color profiles, Bakos et al. (2008)...

Results from a new multi-wavelength evolutionary synthesis model including the γ-ray line emission from various radioactive isotopes (26Al, 60Fe) are presented...

Since its discovery in 1992, the superluminal X-ray transient GRS 1915+105 has been extensively observed in an attempt to understand its behaviour. We present...

To study the small-scale dynamic processes of magneto-convection in the solar photosphere in more detail than currently achieveable, not only the spatial...

Spatial and temporal evolution of dynamic fibrils (DF) as well as coupling with photospheric features was investigated. The main target were remnants in the...
