Subsolar metallicity L subdwarfs was discovered over a decade ago, but remain poor understood due to lack of known objects. We started to search for L subdwarfs...

The Small Magellanic Cloud is a crucial galaxy to understand many aspects of the formation and evolution of galaxies. We propose to collect deep photometry in...

The Carina Nebula is one of the major and more massive regions of our Galaxy that contains a large number of massive O-type stars that can be analyzed...

Gaia, an ESA cornerstone mission, will obtain of the order of 100 high-precision photometric observations and lower precision radial velocity measurements over...

Quantitative seeing measurements have been provided at the Canarian Observatories since 1990 by differential image motion monitors (DIMMs). Image quality needs...

In this contribution we present our on-going project about the understanding of the evolution of galactic OB associations and the implications on the global...

In this proceedings paper we make use of the two-dimensional stellar kinematics of a representative sample of E and S0 galaxies obtained with the SAURON...
