A-F variables from the TESS continuous viewing zone
Astronomical Institute of the Czech Academy of Sciences
The region of the main sequence where A and F stars are located is a transition region of various physical phenomena. This is the reason why we can often observe stars showing signs of rotation, pulsation, chemical peculiarity, binarity, etc. at the same time. To our current knowledge, some of the observed phenomena should not co-exist. I will discuss the identification and classification of the A-F variable stars near the ecliptic pole gathered by the TESS satellite and show some interesting cases.
