Statistical Analyses of Massive Stars and Stellar Populations
(2015-03-04)
Massive stars, i.e. stars more massive than about ten times that of the Sun, are key agents in the Universe. They synthesise many of the chemical elements that are so important for life on Earth, helped reionising the early ...
Massive stars on the main sequence
(2017-03-10)
Massive stars have a strong influence on their environment by chemical enrichment of the surrounding interstellar medium due to strong stellar winds. The influence of mass loss and rotation on the main-sequence evolution ...
Binary star population synthesis: Progenitors of gravitational wave driven mergers
(2018-06-13)
The vast majority of all massive stars are born in binaries. The binarity of a star may influence its life drastically via a large variety of interactions with its companion star. Several astrophysical events, like the ...
Evolution of carbon-enhanced metal-poor stars originating from mass transfer in stellar binaries
(2018-03-26)
As the hydrogen and helium created shortly after the Big Bang is gradually processed into heavier elements by successive generations of stars, the overall metal content of the Universe increases. Metal-poor stars which, ...
The evolution of massive stars in the Small Magellanic Cloud
(2019-03-27)
Massive stars in the early universe are born with only a small amount of heavy elements (or, 'metals’). These metal-poor massive stars played a crucial role in shaping the galaxies in the early universe. They are also the ...
