Bernabéu Física, Astronomía y Matemáticas rays: binaries stars: supergiants Pulsars: individual: Cen X3 The aim of this work is to study both light curve and orbital phase spectroscopy of Cen X-3 taking advantage of the MAXI/GSC observation strategy. These studies allow delimiting the stellar wind properties and its interactions with the compact object. From the analysis of the light curve, we have estimated the orbital period of the binary system and also found possible QPOs around a superorbital period of P superorb = 220 ± 5 days. Both orbital phase-averaged and phaseresolved spectra were extracted and analysed in the 2.0-20.0 keV energy range. Two models have described spectra satisfactorily, a partial absorbed Comptonization of cool photons on hot electrons plus a power law, and a partial absorbed blackbody plus a power law, both modified by adding Gaussian lines. The high value of the X-ray luminosity in the averaged spectrum indicates that the accretion mode is not only due to the stellar wind. 2022 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57175502015 https://www.redalyc.org/journal/571/57175502015/ https://www.redalyc.org/journal/571/57175502015/html/ https://www.redalyc.org/journal/571/57175502015/57175502015.epub https://www.redalyc.org/journal/571/57175502015/movil 10.22201/ia.01851101p.2022.58.02.15 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.58 |
