Magnetic field generation in mergers of massive main-sequence stars
Sebastian T. Ohlmann, Fabian R. N. Schneider, Friedrich K. Roepke +3
Magnetic fields are found in many astrophysical objects, ranging from galaxy clusters to the interstellar medium of galaxies and neutron stars. Strong surface magnetic fields are a…
Localized O production in white dwarf mergers
Alexander Holas, Veronica Agaeva, Friedrich K. Roepke +5
The merger of a He white dwarf (WD) and a CO WD is the favored formation channel for R Coronae Borealis (RCB) stars. These stars exhibit ratio…
Good things always come in 3s: trimodality in the binary black-hole chirp-mass distribution supports bimodal black-hole formation
Reinhold Willcox, Fabian R. N. Schneider, Eva Laplace +7
The latest GWTC-4 release from the LIGO-Virgo-KAGRA (LVK) collaboration nearly doubles the known population of double compact object mergers and reveals a new trimodal structure in…
A fundamental limit to how close binary systems can get via stable mass transfer shapes the properties of binary black hole mergers
Jakub Klencki, Philipp Podsiadlowski, Norbert Langer +4
Mass transfer in binary systems is the key process in the formation of various classes of objects, including merging binary black holes (BBHs) and neutron stars. Orbital evolution…
