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 ...
Spectroscopic behavior of some He peculiar stars
(University of Chicago Press, 2007-12-07)
In this work we determine fundamental parameters (Teff and log g) of a sample of He-peculiar stars from the continuum energy distribution around the Balmer discontinuity. Furthermore, we search for optical line variability ...
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 ...
