Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
The BLOeM campaign presents the first large‑scale spectroscopic survey of 929 massive stars in the Small Magellanic Cloud, revealing a high intrinsic binary fraction (>70%) among m…
The Best Guess: Testing new and old formalisms for the common envelope against observations
Riley Thai, Amanda Karakas, Zara Osborn +4
We present a systematic test of formalisms for common envelope evolution by forward-modelling observable post-common envelope binaries. We compare predictions from the -formalis…
A method for constructing the joint mass function of binary stars
Amery Gration, Robert G. Izzard, Payel Das
The initial mass function (IMF) describes the distribution of stellar masses in a population of newly born stars and is amongst the most fundamental concepts in astrophysics. It is…
Using Binary Population Synthesis to Calculate the Yields of Low- and Intermediate-Mass Binary Populations at Low Metallicity
Zara Osborn, Amanda Karakas, Devika Kamath +3
Asymptotic giant branch (AGB) stars are important to chemical evolution at metallicity () as they contribute significantly to the produc…
Stellar velocity distributions in binary-rich ultrafaint dwarf galaxies
Amery Gration, David D. Hendriks, Payel Das +2
Ultrafaint dwarf (UFD) galaxies are dominated by dark matter, the distribution of which may be inferred from the kinematics of that galaxy's stellar population. Star-by-star observ…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
