Sign Up to like & getrecommendations! Published in 2017 at "Astronomische Nachrichten"
DOI: 10.1002/asna.201713441
Abstract: Although the detailed structure of neutron stars remains unknown, their equilibrium temperatures lie well below the Fermi temperature of dense nuclear matter, suggesting that the nucleons in the stars' core form Cooper pairs and exhibit… read more here.

DOI: 10.1002/asna.20240150
Abstract: To model the structure of neutron stars (NSs) theoretically, it is common to consider layers with different density regimes. Matching the equation of state (EoS) for the crust and core and obtaining a suitable description… read more here.

DOI: 10.1002/ctpp.202400004
Abstract: Crystallization of dense matter in neutron star crusts and white dwarf cores may be similar to epitaxial crystal growth in terrestrial laboratories. However, in stellar crystals, the spacing between horizontal planes has to gradually increase… read more here.
