On the incidence of chemically peculiar stars in the Large Magellanic Cloud
(Oxford University Press, 2005-09)
With the aim to corroborate the result of a search for chemically peculiar stars in the Large Magellanic Cloud (LMC), we present measurements obtained from CCD imaging of two fields, one containing a young open cluster ...
Spectroscopic variability and magnetic fields of HgMn stars
(Wiley Vch Verlag, 2011-12)
The discovery of exotic abundances, chemical inhomogeneities, and weak magnetic fields on the surface of late B-type primaries in spectroscopic binaries has important implications not only for our understanding of the ...
A probable pre-main sequence chemically peculiar star in the open cluster Stock 16
(Oxford University Press, 2014-07)
We used the Ultraviolet and Visual Echelle Spectrograph of the ESO-Very Large Telescope to obtain a high resolution and high signal-to-noise ratio spectrum of Stock 16-12, an early-type star which previous Δa photometric ...
Chemically peculiar stars in the Large Magellanic Cloud
(EDP Sciences, 2006-12)
Context. The detection of magnetic chemically peculiar (CP2) stars in open clusters of extragalactic systems can give observational answers to many unsolved questions. For example, one can study the influence of different ...
Possible signature of hypernova nucleosynthesis in a beryllium-rich halo dwarf
(WILEY-BLACKWELL, 2008)
As part of a large survey of halo and thick disc stars, we found one halo star, HD106038, exceptionally overabundant in beryllium. In spite of its low metallicity, [Fe/H] = -1.26, the star has log(Be/H) = -10.60, which is ...
