A study of the correlation of the morphology of a complete sample of 255 galactic planetary nebulae (PNe) with their nebular parameters is presented here...

We have obtained (in BVRI filters) the structural parameters of four disk galaxies, spanning a range of different morphological types. We believe the parameters...

We review some of the statistical properties of higher-dimensional superstatistical stochastic models. As an example, we analyse the stochastic properties of a...

We have found a large amount of 6Li in the atmosphere of the star HD 82943 which harbors two planets. From the amount of lithium in the star's atmosphere, we...

Asymptotic giant branch (AGB) stars synthetise a variety of elements in their deep hot layers, mix them to the stellar surface, and shed them into their...

We present results on the cosmic evolution of the outskirts of disk galaxies. In particular we focus on galaxies with stellar disk truncations. Using UDF, GOODS...

We present our recent results on the cosmic evolution of the outskirts of disk galaxies. In particular we focus on disk-like galaxies with stellar disk...

An extraordinary recent development in astrophysics was the discovery of the fossil relationship between central black hole mass and the stellar mass of...

Magnetic fields play an important role in many astrophysical processes. They are difficult to detect and characterize since often their properties have to be...
