Correlation and evolution of the blazar S5 1803+784 short-term variability properties during 01.2022-01.2023
Аннотация:
The blazar S5 1803+784 has a unique high temporal resolution data series for about a year provided by the TESS satellite. By performing our aperture photometry of summarized on 10-30 the full-frame image cuts to reduce Poisson noise, we obtained the blazar light curve from 01.2022 to 01.2023. Using a new method for determining the shortest characteristic variability time and supplementing the study with data from long-term multiband ZTF and AZT-8 observations, we trace the evolution of the micro-variability parameters and their correlation to the long-term variability characteristics. We draw a conclusion regarding the mechanism, forming the S5 1803+784 micro-variability.
