A peculiar planetary nebula candidate in a globular cluster in the Fornax dwarf spheroidal galaxy
Context. Until now, only one planetary nebula (PN) has been known in the Fornax dwarf spheroidal galaxy. Aims. The discovery of a second PN candidate, associated with one of the 5 globular clusters in the Fornax dwarf, is reported. Methods. Spectra of the globular cluster H5, obtained with the UVES echelle spectrograph on the ESO Very Large Telescope, show [O ] line emission at a radial velo...
متن کاملThe Planetary Nebula population of the Sagittarius Dwarf Spheroidal Galaxy
The identification of two new Planetary Nebulae in the Sagittarius Dwarf Spheroidal Galaxy (Sgr) is presented. This brings the total number to four. Both new PNe were previously classified as Galactic objects. The first, StWr 2-21, belongs to the main body of Sgr, from its velocity and location. The second, the halo PN BoBn 1, has a location, distance and velocity in agreement with the leading ...
متن کاملVariable Stars in the Fornax Dwarf Galaxy
We have surveyed a 40' X 40' field. We have obtained 20 epochs with the MACHO camera (filters VyiRu) on the 1.3-m telescope (Mt Stromlo) and 15 VI epochs on the 1-m telescope at Siding Spring, over a time interval of five months. To look for variables, we used the method proposed by Welch & Stetson (1993). The variability index Jws is plotted in Fig. 1. Non-variable stars cluster around 0. The ...
متن کاملThe stellar populations of the Fornax dwarf spheroidal galaxy
We present B, V, I CCD photometry of about 40000 stars in four regions of the Fornax dwarf spheroidal galaxy down to V ∼ 23.5, the largest three-color data set obtained for this galaxy until now. The resultant color-magnitude diagrams, based on a wide color baseline, show a variety of features tracing the history of star formation of this dwarf galaxy. One of the most distinctive features in ou...
متن کاملThe early - type dwarf galaxy population of the Fornax cluster
Aims. We analyse the photometric properties of the early-type Fornax cluster dwarf galaxy population (M V > −17 mag), based on a wide field imaging study of the central cluster area in V and I bandpasses. We used the instrument/telescope combination IMACS/Magellan at Las Campanas Observatory, providing much larger light collecting area and better image resolution than previous wide field imagin...
