Robustness of Magnetic Field Amplification in Neutron Star Mergers
Ricard Aguilera-Miret, Jan-Erik Christian, Stephan Rosswog +1
The dynamics of a binary neutron stars merger is governed by physics under the most extreme conditions, including strong spacetime curvature, ultra-high matter densities, luminous…

Comprehensive Analysis of Constructing Hybrid Stars with an RG-consistent NJL Model
Jan-Erik Christian, Ishfaq Ahmad Rather, Hosein Gholami +1
In this work, we investigate the properties of hadronic and quark matter that would allow for a first order phase transition between them within neutron stars. To this end, we use…

Constraining twin stars with cold neutron star cooling data
Melissa Mendes, Jan-Erik Christian, Farrukh J. Fattoyev +1
We investigate the influence of a phase transition from hadronic matter to a deconfined quark phase inside a neutron star on its cooling behaviour including the appearance of twin…
