Optical spectroscopy of X-Mega targets in the Carina nebula, VII: on the multiplicity of Tr 16-112, HD 93343 and HD 93250
(Wiley Blackwell Publishing, Inc, 2009-09)
We present the results of a spectroscopic monitoring campaign devoted to three O-type stars in the Carina nebula. We derive the full SB2 orbital solution of the binary system Tr 16-112, an exceptional dissymmetrical system ...
Radio Detection of Colliding Wind Binaries
(Cambridge University Press, 2006-01)
Four massive, early-type stars, three of which are confirmed binaries, have been observed with theAustralia Telescope Compact Array at 1.4, 2.4, 4.8, and 8.6 GHz. The earliest star cataloged so far, HD 93129A,was also ...
Spectroscopic and photometric analysis of the early-type spectroscopic binary HD 161853 in the centre of an H ii region (Research Note)
(Edp Sciences, 2015-12)
Aims. We study the O-type star HD 161853, which has been noted as a probable double-lined spectroscopic binary system.
Methods. We secured high-resolution spectra of HD 161853 during the past nine years. We separated the ...
Apsidal motion in massive close binary systems. I. HD 165052 an extreme case?
(Oxford University Press, 2013-06)
We present a new set of radial-velocity measurements of the spectroscopic binary HD 165052 obtained by disentangling of high-resolution optical spectra. The longitude of the periastron (60 +- 2 degrees) shows a variation ...
