Abstract
The results of the analysis of the flares activity of EXO 040830-7134.7 according to the data of the TESS project are presented. The most typical flares have been demonstrated. It was determined that out of 88 selected flares, 17 are superflares with energy of more than 1034 erg. Flares considered in this work have energy in the range from 8.4 × 1032 to 9 × 1034 erg. The relation between the phase of the rotation period and high-energy flares is noted. Low-energy flares are distributed evenly, while more powerful events (more 1034 erg) mainly correspond in regional of increasing and decreasing the brightness on phases light curve. Analysis of 23 sets of observations showed that the period of axial rotation is 5.17 days. [ABSTRACT FROM AUTHOR]
