The Evolution of Massive Stellar Multiplicity in the Field I. Numerical simulations, long-term evolution and final outcomes
Holly P. Preece, A. Vigna-Gómez, A. S. Rajamuthukumar +2
We investigate how the multiplicity of binary, triple and quadruple star systems changes as the systems evolve from the zero-age main-sequence to the Hubble time. We find the chang…

Supernova Shocks Cannot Explain the Inflated State of Hypervelocity Runaways from White Dwarf Binaries
Aakash Bhat, Evan B. Bauer, Rüdiger Pakmor +5
Recent observations have found a growing number of hypervelocity stars with speeds of km\,s which could have only been produced through thermonuclear su…

Large-scale ordered magnetic fields generated in mergers of helium white dwarfs
Rüdiger Pakmor, Ingrid Pelisoli, Stephen Justham +9
Stellar mergers are one important path to highly magnetised stars. Mergers of two low-mass white dwarfs may create up to every third hot subdwarf star. The merging process is usual…
