Publikováno v: Revista de Estabilidad Financiera. :39-70

Los mercados de derivados energéticos se vieron sumidos en turbulencias tras la invasión de Ucrania por parte de Rusia, ya que los precios del gas natural y de la electricidad se dispararon, en un contexto de volatilidad elevada y de deterioro sign

We report the analysis of high temporal resolution ground and space based photometric observations of SZ Lyncis, a binary star one of whose components is a high amplitude $\delta$ Scuti. UBVR photometric observations were obtained from Mt. Abu Infrar

Recently, it has been found that off-centre carbon burning in a subset of intermediate-mass stars does not propagate all the way to the center, resulting in a class of hybrid CONe cores. Here, we consider the possibility that stars hosting these hybr

The gravitational collapse of ONe electron-degenerate cores and white dwarfs: The role of $^\mathsf{24}$Mg and $^\mathsf{12}$C revisited

The final stages of the evolution of electron--degenerate ONe cores, resulting from carbon burning in ``heavy weight'' intermediate--mass stars ($8 M_{\sun}\la M \la 11 M_{\sun}$) and growing in mass, either from carbon burning in a shell or from acc

Aims. Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O yields of these stars. Methods. Using the Monash University Stellar
