Dynamical Masses and Radiative Transfer Modeling of HD 698: a Be Binary in Evolutionary Transition
Ilfa A. Gabitova, Alex C. Carciofi, Tajan H. de Amorim +13
We present a detailed analysis of the early post-mass-transfer binary HD 698 (V742 Cas) combining high-resolution optical spectroscopy, long-baseline interferometry, and radiative-…

Binary stars take what they get: Evidence for Efficient Mass Transfer from Stripped Stars with Rapidly Rotating Companions
Thibault Lechien, Selma E. de Mink, Ruggero Valli +5
Binary stars and their interactions shape the formation of compact binaries, supernovae, and gravitational wave sources. The efficiency of mass transfer - the fraction of mass reta…

Evidence of polar and ultralow supernova kicks from the orbits of Be X-ray binaries
Ruggero Valli, Selma E. de Mink, Stephen Justham +7
Supernovae, the explosive deaths of massive stars, create heavy elements and form black holes and neutron stars. These compact objects often receive a velocity at formation, a "kic…
