To warn about potential asteroid or comet impacts, we must first observe and discover these objects through dedicated NEO surveys. Most current and planned...

A survey of Ne, O and Fe coronal abundances culled from the recent literature for about 60 late-type stars confirms that the Ne/O ratio of stellar outer...

NEREA is a stable, compact, high-resolution spectrometer concept for the GTC. NEREA is proposed as a general purpose instrument with a variety of science cases...

We analyze the observed properties of nested and single stellar bar systems in disk galaxies. Our sample consists of 56 Seyfert and 56 non-Seyfert galaxies. We...

We studied the SB0 galaxy NGC 2950, which hosts two nested stellar bars. We used the Tremaine-Weinberg method to measure the pattern speed of the primary bar...

Sunspot penumbrae harbor highly structured magnetic fields and flows. The moving flux tube model offers an explanation for several observed phenomena, e.g. the...
