Possible optical detection of a fast, nearby radio pulsar PSR B1133+16
S. V. Zharikov, Yu. A. Shibanov, R. E. Mennickent +1
Aims: We performed deep optical observations of the field of an old, fast-moving radio pulsar PSR B1133+16 in an attempt to detect its optical counterpart and a bow shock nebula. M…
Dark-Matter Content of Early-Type Galaxies with Planetary Nebulae
N. R. Napolitano, A. J. Romanowsky, L. Coccato +10
We examine the dark matter properties of nearby early-type galaxies using planetary nebulae (PNe) as mass probes. We have designed a specialised instrument, the Planetary Nebula Sp…
Stroemgren photometry of Galactic Globular Clusters. I. New Calibrations of the metallicity index
A. Calamida, G. Bono, P. B. Stetson +15
We present a new calibration of the Stroemgren metallicity index m1 using red giant (RG) stars in 4 globular clusters (GCs:M92,M13,NGC1851,47Tuc) with metallicity ranging from [Fe/…
Formation History of Stars and Star Clusters in Nearby Galaxies
S. S. Larsen, M. D. Mora, J. P. Brodie +1
We present first results from an HST/ACS imaging survey of stars and star clusters in five nearby spiral galaxies. This contribution concentrates on NGC 1313, a highly distorted la…
