On the nature of oscillating modes of proto-neutron stars
Dimitra Tseneklidou, Alejandro Torres-Forne, Pablo Cerda-Duran +2
Newborn proto-neutron stars (PNS) are potential targets of gravitational wave asteroseismology, the study of the (inner) structure of stars via their oscillation modes. To prepare…
Diffuse Neutrino Background from Magnetorotational Stellar Core Collapses
Pablo MartÃnez-Miravé, Irene Tamborra, Miguel Ãngel Aloy +1
A statistically significant detection of the diffuse supernova neutrino background (DSNB) is around the corner. To this purpose, we assess the contribution to the DSNB of magnetoro…
Impact of the equation of state on core collapse supernovae I: the low- instability
Marco Cusinato, Martin Obergaulinger, Miguel Ãngel Aloy
Rapidly rotating core-collapse supernovae are promising sources of multimessenger emission, as non-axisymmetric dynamics in the newly formed proto-neutron star can leave characteri…
The first 3D MHD core-collapse progenitors II: Rotation, magnetic-field amplification, and magnetic topology
Adam Griffiths, Miguel-Ãngel Aloy, Martin Obergaulinger
The most energetic core-collapse supernovae are thought to arise from rapidly rotating, magnetised progenitors. However, the three-dimensional pre-collapse structure of their angul…
The first 3D MHD core-collapse progenitors I: General properties, convection and nuclear burning
Adam Griffiths, Miguel-Ãngel Aloy, Martin Obergaulinger
The most energetic core-collapse supernovae are thought to arise from rapidly rotating, magnetised progenitors, yet the three-dimensional structure of their pre-collapse interior r…
Time integration for neutrino radiation transport using minimally implicit Runge-Kutta methods
Samuel Santos-Pérez, Martin Obergaulinger, Isabel Cordero-Carrión
The evolution of many astrophysical systems is dominated by the interaction between matter and radiation such as photons or neutrinos. The dynamics can be described by the evolutio…
