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...

We present a preliminary analysis of visible + infrared spectra (0.5 2.4 μm) of 17 asteroids in cometary orbits (ACOs), asteroidal objects with Tisserand...

(596) Scheila is a large primitive asteroid observed with a comet-like apearence last December. We present near-infrared spectra (0.8-2.4 μm) obtained at...

V1647 Ori is a young eruptive variable star, illuminating a reflection nebula (McNeil's Nebula). It underwent an outburst in 2003 before fading back to its pre...

We present preliminary results of the surface photometry of a sample of blue compact dwarf galaxies (BCDGs). A total of 28 galaxies have been observed in the...
