Improving transit characterisation with Gaussian process modelling of stellar variability
(EDP Sciences, 2020-02)
Context. New photometric space missions to detect and characterise transiting exoplanets are focusing on bright stars to obtain high cadence, high signal-to-noise light curves. Since these missions will be sensitive to ...
Effects of Hadron-Quark Phase Transitions in Hybrid Stars within the NJL Model
(Multidisciplinary Digital Publishing Institute, 2019-03-22)
We study local and non-local Polyakov Nambu-Jona-Lasinio models and analyze their respective phase transition diagram. We construct hybrid stars using the zero temperature limit of the local and non-local versions of ...
On the line shift and oscillator strength of Xe II lines in the spectra of HnMn stars
(EDP Sciences, 2015-07)
Aims. The ultimate goal that has motivated this work is to achieve realistic oscillator strength (gf) values to find reliable values of stellar abundances. We aim to compare the gf valúes of Xe ii lines found with different ...
