We present V, I CCD photometry of the Sextans dwarf spheroidal galaxy (dSph) in the Local Group. Images of the galaxy were taken by Suprime-Cam on Subaru, covering 26 fields extended to the tidal radius. The color-magnitude diagrams extending two magnitudes below the main-sequence turnoff (MSTO) show a steep red giant branch (RGB), blue and red

The Star Formation of a Giant H II Region in M 101
We present a study of the star formation process in the giant H II region NGC 5471 in the outskirts of M 101 from both integrated and resolved photometry. Stellar population analysis with the code CHORIZOS is compatible with the hypothesis that this regions has, at least, two different populations. The color-magnitude diagram of the region as

The STELLA robotic observatory
STELLA is a robotic observatory with two fully automatic telescopes (STELLA-I and STELLA-II) located at the Teide Observatory in Tenerife, Spain. Not only the telescopes are automatic but also the entire observatory, no human presence is needed for observing - not even in remote control. STELLA-I supports a high-resolution, fiber-fed and bench

The stellar occultation by Makemake on 2011 April 23
We have taken advantage of a stellar occultation by the dwarf planet Makemake on 2011 April 23, to determine several of its main physical properties. We present results from a multisite campaign with 8 positive occultation detections from 5 different sites, including data from the 8-m VLT and 3.5-m NTT telescopes in Chile, which have very high

The structure of BB Doradus in quiescence
Spectroscopic observations during a low state of BB Dor reveal a complex emission distribution. Irradiation by the white dwarf as well as magnetic fields of the secondary star are needed for an explanation.

The Substellar Domain in the ɛ Orionis Cluster
We present an IZ photometric survey covering a total area of about 1000 arcmin2 around the ɛ Orionis young massive star (˜10 Myr, d=412 pc) and reaching a limiting magnitude I=22. From the resulting I, I-Z color-magnitude diagram we have selected 123 red candidates in the interval I=15--22 mag, which according to evolutionary models corresponds to
