DOI: 10.1093/mnras/sty253
Abstract: Space observatories such as $\textit{Kepler}$ have provided data that can potentially revolutionise our understanding of stars. Through detailed asteroseismic analyses we are capable of determining fundamental stellar parameters and reveal the stellar internal structure with… read more here.

DOI: 10.1103/physrevd.100.045002
Abstract: In the present paper, discussion of perturbations against a Q-ball solution is continued. It is shown that in order to correctly describe perturbations containing non-oscillation modes, it is also necessary to consider nonlinear equations of… read more here.
