Chemodynamic evolution of Sun-like stars in nearby moving groups

Christian Lehmann, Michael T. Murphy, Fan Liu +1

Sun-like stars are well represented in the solar neighbourhood but are currently under-utilised, with many studies of chemical and kinematic evolution focusing on red giants (which…

A new sample of massive B-type contact binary candidates from the OGLE survey of the Magellanic Clouds

Athira Menon, Michal Pawlak, Daniel J. Lennon +2

Massive contact binaries (CBs) are key to understanding close-binary evolution and stellar mergers, yet their study has been limited by the scarcity of observed systems, particular…

Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC

T. Shenar, J. Bodensteiner, H. Sana +74

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 p…
