THE ARAUCARIA PROJECT: A STUDY OF THE CLASSICAL CEPHEID IN THE ECLIPSING BINARY SYSTEM OGLE LMC562 05 9009 IN THE LARGE MAGELLANIC CLOUD
... The p-factor value for the Cepheid is marginally consistent with the prediction of the p-factor relation of Storm et al. ( 2011 ) , as opposed to the p-factor we derived for OGLE-LMC- CEP-0227 in P13, which is in signi fi ...

Unveiling the nature of INTEGRAL objects through optical spectroscopy X A new multi year, multi observatory campaign
... Within the framework of our program (running since 2004) of identification of hard X-ray INTEGRAL sources through optical spectroscopy, we present the results concerning the nature of 33 high-energy objects. The data ...

Globular Clusters and X Ray Point Sources in Centaurus A (NGC 5128)
... A few outlying X-ray sources in the BVI diagram are quite faint, and could represent contaminant sources (foreground stars or background galaxies). Furthermore, a few objects, shown in the (B V ) versus V plot, show ...
