We have analyzed in detail the discovery measurements of the X-ray burster SAX J1750.8-2900 by the Wide Field Cameras on board BeppoSAX in spring 1997, at a position ~1.2d off the Galactic center. The source was in outburst on March 13 when the first observation started and showed X-ray emission for ~2 weeks. A total of nine bursts were detected

We present results from multi-wavelength observations of the Wolf-Rayet (WR) blue compact dwarf galaxy He 2-10. These observations include Hα and optical red continuum imaging, high resolution Hα spectroscopy, high resolution radio-continuum mapping at 4.80 and 8.64 GHz and ROSAT X-ray observations. The deep Hα images reveal that the galaxy is

We present the second part of the results of our spectroscopic study of orbital phase resolution of short-period active binaries. In this paper we present the observations of the binaries RT And, WY Cnc, and XY UMa, for which we obtained simultaneous low-resolution spectra in the Hα, Hβ, and Ca II infrared triplet (IRT; 8498 and 8542 Å) lines, and

We present new deep VI ground-based photometry of the Local Group dwarf galaxy Phoenix. Our results confirm that this galaxy is mainly dominated by red stars, with some blue plume stars indicating recent (100 Myr old) star formation in the central part of the galaxy. We have performed an analysis of the structural parameters of Phoenix based on an
