A semi-analytical approach to cosmic void evolution
A. N. Baushev, A. G. Nikiforov, M. V. Barkov
We present a theoretical study of the non-linear evolution of cosmic voids -- underdense regions that occupy a large fraction of the observable Universe. We model a void as an isol…
Modeling of the magnetic stellar wind braking of the ssrAp 33 Lib (HD137949)
A. G. Nikiforov, V. D. Bychkov, M. V. Barkov
Using the ssrAp star 33 Lib (HD137949) as an example, we show that magnetic braking caused by the interaction of a strong magnetic field with a stellar wind can play a key role in…
Production of Jets before Neutron Star Mergers
Praveen Sharma, Slava G. Turyshev, Maxim V. Barkov +1
We demonstrate that magnetospheric interactions between merging neutron stars (NSs) generate dual-jetted current outflows, analogous to the Alfvén wings observed during planetary…
Magnetar-like flares behind the high-energy emission in LS 5039
V. Bosch-Ramon, M. V. Barkov
LS 5039 hosts a high-mass star, and a compact object that might be a strongly magnetized neutron star (NS). This scenario requires a mechanism to power its persistent and strong no…
The impact of the eccentricity on the collapse of an ellipsoid into a black hole
A. G. Nikiforov, A. N. Baushev, M. V. Barkov
We consider the gravitational collapse of a homogeneous pressureless ellipsoid. We have shown that the minimal size that the ellipsoid can reach during collapse depends on its…
Supernova-induced binary-interaction-powered supernovae: a model for SN2022jli
Ryosuke Hirai, Philipp Podsiadlowski, Peter Hoeflich +4
We present 3D hydrodynamical modelling of supernova-induced binary-interaction-powered supernovae; a scenario proposed for the peculiar type Ic supernova SN2022jli. In this scenari…
