Nuclear processes in astrophysics: Recent progress
Malheiro, M.; Liccardo, V.; Hussein, M. S. +2 more
The question about the origin of the elements is a fascinating one, that scientists have been trying to answer for the last seven decades. The formation of light elements in the primordial universe and heavier elements in astrophysical sources occurs through nuclear reactions. We can say that nuclear processes are responsible for the production of…
Measuring the basic parameters of neutron stars using model atmospheres
Werner, K.; Klochkov, D.; Poutanen, J. +1 more
Model spectra of neutron star atmospheres are nowadays widely used to fit the observed thermal X-ray spectra of neutron stars. This fitting is the key element in the method of the neutron star radius determination. Here, we present the basic assumptions used for the neutron star atmosphere modeling as well as the main qualitative features of the s…
