In this work, light curves were analyzed through plots of the light intensity of fifteen celestial objects called high mass X-ray binary systems, HMXRBs, as a function of time. The light curves were obtained from Period04 from the High Energy Astrophysics Science Archive Research Center of NASA’s HEASARC, National Aeronautics and Space Administration Goddard Space Flight Center, Rossi X-ray Timing Explorer (RXTE), Guest Observer Facility—NASA and INTEGRAL Data Archives—ESA's Cosmos databases. HMXRBs are stellar binary systems composed by an O-B star and a compact object (neutron star or black hole), systems with a super-giant companion, systems with a main-sequence companion, weird systems, unveiled by Roche-lobe overflow, wind-fed accretion, circumstellar disk, supergiant fast X-Ray transients and homogeneous stellar wind. The objective was to analyze the variability of light curves of X-ray sources, and thus, to provide relevant information on the temporal behavior of these astrophysical objects through their physical and/or geometrical parameters in order to understand the processes experienced by these binaries. From the results obtained, it was found that the type of variability of HMXRBs in some of the sources is due to orbital motion, neutron star rotation and periodic motions of material. Periodic and aperiodic light curves were found and their study allowed us to provide information on the physical processes that produce them and obtain results similar to those of other authors who have studied this type of binary using other techniques, such as variability that can give rise to the system's superorbital period, as well as a possible linear relationship. The command line tool called Period04 was used to perform Fourier temporal analysis obtaining the periodogram of each source. The calculation of the periods and frequencies was executed with the corresponding error of both subdividing the light curve into time intervals or without subdividing according to its appearance, if there are bursts, etc. and with this, the variability of the sources was obtained. The contribution of this work to the area of high-energy astrophysics focuses on giving information on phenomena that produce variability in X-rays through the qualitative analysis of light curves of the sources that involve its physical processes.

摘要

In this work, light curves were analyzed through plots of the light intensity of fifteen celestial objects called high mass X-ray binary systems, HMXRBs, as a function of time. The light curves were obtained from Period04 from the High Energy Astrophysics Science Archive Research Center of NASA’s HEASARC, National Aeronautics and Space Administration Goddard Space Flight Center, Rossi X-ray Timing Explorer (RXTE), Guest Observer Facility—NASA and INTEGRAL Data Archives—ESA's Cosmos databases. HMXRBs are stellar binary systems composed by an O-B star and a compact object (neutron star or black hole), systems with a super-giant companion, systems with a main-sequence companion, weird systems, unveiled by Roche-lobe overflow, wind-fed accretion, circumstellar disk, supergiant fast X-Ray transients and homogeneous stellar wind. The objective was to analyze the variability of light curves of X-ray sources, and thus, to provide relevant information on the temporal behavior of these astrophysical objects through their physical and/or geometrical parameters in order to understand the processes experienced by these binaries. From the results obtained, it was found that the type of variability of HMXRBs in some of the sources is due to orbital motion, neutron star rotation and periodic motions of material.
