One of the great things about modern-day space telescopes is that the data they produce, which is eventually released to the public, contains useful information. Astronomers can use their own ideas to sift through the data An amazing 25,229 stars with solar flares were found by a team from Poland.
The stars emitted over a hundred thousand flares. Each star was observed on average for 25 days, which is a significant amount of data considering a total of 320,000 stars from TESS's first 39 "sectors" of observation.
The authors of the study developed a software called Warrior which was used to find and analyze solar flares. Our own Sun has a typical power flare energy of 10 27 erg. Many smaller flares were not visible to TESS at that distance.
There were many patterns in the data. Potential false positives, such as local asteroids, had to be eliminated by Warner. F1 is the hottest type of F star and has a mass 1.6 times that of the Sun.
Most of the stars that exhibited flares did not have a high temperature.
Statistics found in other stellar flare studies are confirmed by much of this study. Science goes forward when the data is verified. The way in which these data were collected and analyzed makes the study interesting in its own right. There will be similar studies with more access to data from even more advanced space telescopes and more people trying to analyze that data.

The first three years of TESS observations yielded a statistical analysis of stellar flares.
The sun is not as active as other stars.
There is a solar flare on another star.
If it happened here, it would be terrible.
