Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC Open
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary properties of massive stars at low metallicity, which approa…

An absence of binary companions to Wolf-Rayet stars in the Small Magellanic Cloud Open
To predict black hole mass distributions at high redshifts, we need to understand whether very massive single stars ( M ≳ 40 M ⊙ ) with low metallicities ( Z ) lose their hydrogen-rich envelopes, like their metal-rich counterparts, or whet…

X-rays observations of a super-Chandrasekhar object reveal an ONe and a CO white dwarf merger product embedded in a putative SN Iax remnant Open
The merger of two white dwarfs (WDs) is a natural outcome of the evolution of many binary stars. Recently, a WD merger product, IRAS 00500+6713, was identified. IRAS 00500+6713 consists of a central star embedded in a circular nebula. The …
