The purpose of the research is to study the fine structure of radiation of space objects, estimation of their photometric and spectral characteristics, development hardware and software, matrix development and implementation spectrophotometer for fast photometry and spectrometry of stars. popup.description2 The object of study: flaring stars, chromospherically active and hot stars, spectrophotometry of meteors, unknown air phenomena. Objective: Investigation of the rapid photometric and spectral variability of stars and meteors Research methods: conducting observations, developing methods of statistical spectrophotometry, and mathematical processing of observations. During the reporting period (2020-2024), the following work was performed: - Methods for spectrometric observations with high temporal resolution were developed. - Spectrophotometric observations of flaring, hot, and chromospherically active stars were carried out. - The data were mathematically processed. - The search for flaring stars and the study of their fine structure were performed. - Mathematical software for statistical spectrophotometry and analysis of stellar wind and starbursts was developed. - Based on the methods of coronal seismology and solar-stellar analogy, the parameters of coronal loops on YZ CMi, AR Lac were estimated. - New methods for spectrophotometry of meteors are developed - Observations of unknown aerial phenomena were carried out   Product Description popup.authors Verliuk Iryna A.
