Discovery of new mercury-manganese stars, including a fast rotator
(Wiley Blackwell Publishing, Inc, 2021-04-19)
The origin of mercury-manganese (HgMn) stars is still poorly understood and the statistical analysis of an extensive sample of well characterized objects would be very valuable. Nevertheless, the compilation of a clean and ...
Non-thermal radio emission from OB stars: an observer’s view
(Astromical Society of the Pacific, 2010-05)
Some early-type stars are detectable radio emitters; their spectra can present both thermal and non-thermal contributions. Here I review the public radio data on OB stars, focusing on the non-thermal sources. The analysis ...
TOWARD UNDERSTANDING THE B[e] PHENOMENON. IV. MODELING OF IRAS 00470+6429
(IOP PUBLISHING LTD, 2010)
FS CMa type stars are a recently described group of objects with the B[e] phenomenon which exhibits strong emission-line spectra and strong IR excesses. In this paper, we report the first attempt for a detailed modeling ...
The Galactic O-Star Spectroscopic Survey (GOSSS). II : bright southern stars
(Iop Publishing, 2014-03)
We present the second installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R ~ 2500 digital observations from both hemispheres selected from the ...
Magnetic fields of HgMn stars
(EDP Sciences, 2012-11)
Context. The frequent presence of weak magnetic fields on the surface of spotted late-B stars with HgMn peculiarity in binary systems has been controversial during the two last decades. Recent studies of magnetic fields ...
