Journal ArticleDOI
The "hidden" companion in LB-1 unveiled by spectral disentangling
Tomer Shenar,J. Bodensteiner,Michael Abdul-Masih,M. Fabry,Laurent Mahy,Pablo Marchant,G. Banyard,Dominic M. Bowman,K. Dsilva,C. Hawcroft,Maddalena Reggiani,Hugues Sana +11 more
TL;DR: In this article, the authors performed an orbital analysis and spectral disentangling of LS V +22 25 (LB-1) to elucidate the nature of the system, which revealed that LB-1 contains two components of comparable brightness in the optical.
Journal ArticleDOI
On the signature of a 70-solar-mass black hole in LB-1
Michael Abdul-Masih,G. Banyard,J. Bodensteiner,Emma Bordier,Dominic M. Bowman,K. Dsilva,M. Fabry,C. Hawcroft,Laurent Mahy,Pablo Marchant,Gert Raskin,Maddalena Reggiani,Tomer Shenar,Andrew Tkachenko,Hans Van Winckel,L. Vermeylen,Hugues Sana +16 more
TL;DR: It is shown that the apparent shifts of the Hα emission line used to derive the mass of the black hole arise from the orbital motion of the B-type companion star in the LB-1 binary system and not from that of theblack hole, removing the existing tension between its proposed existence and models of the formation of such a massive black hole at galactic metallicity.
Journal ArticleDOI
No signature of the orbital motion of a putative 70 solar mass black hole in LB-1.
Michael Abdul-Masih,G. Banyard,J. Bodensteiner,Dominic M. Bowman,K. Dsilva,M. Fabry,C. Hawcroft,Laurent Mahy,Pablo Marchant,Gert Raskin,Maddalena Reggiani,Hugues Sana,Tomer Shenar,Andrew Tkachenko,Hans Van Winckel,L. Vermeylen +15 more
TL;DR: In this article, Liu et al. showed that the observational diagnostics used to derive the BH mass results from the orbital motion of the B-type star, not that of BH, therefore solving the existing tension with formation models of such a massive BH at solar metallicity and with theories of massive star evolution.

Is HR 6819 a triple system containing a black hole? - An alternative explanation
J. Bodensteiner,Tomer Shenar,Laurent Mahy,M. Fabry,Pablo Marchant,Michael Abdul-Masih,G. Banyard,Dominic M. Bowman,K. Dsilva,A. J. Frost,C. Hawcroft,Maddalena Reggiani,Hugues Sana +12 more
TL;DR: In this paper, the authors investigated the properties of HR 6819 to search for a possibly simpler alternative explanation for HR6819, which does not invoke the presence of a triple system with a BH in the inner binary.
