Morphological variability classes. We include some examples of stars representing the classes described in Section 2. (P) The star TIC 50657928 shows a periodic LC. (Pn) The star TIC 11296154 shows a periodic LC with significant noise. (N) The star TIC 249040852 exhibits a noisy LC, in which brightness variability is not detected. (Pi) The star TIC 50792805 exhibits a periodic LC with an overall increase in brightness. (Pd) The star TIC 249070479 shows a periodic LC with an overall decrease in brightness. (L) The star TIC 436013242 has a long-term variability. (MP) The star TIC 50748110 shows an LC with at least two periodic signals. (Pia) The star TIC 50622261 shows a periodic LC in which the variability amplitude increases with time. (Pda) The star TIC 4352899 shows a periodic LC in which the variability amplitude decreases with time. (EB) The star TIC 72829000 exhibits a typical Algol eclipsing binary LC. (D) The star TIC 11453668 shows an LC with sudden decreases (dips) in brightness, and (B) the star TIC 11296297 shows an LC with sudden increases (bursts) in brightness. Since we expect asymmetries in the brightness distribution in both dippers and bursters, we have joined them in a single class called the DB class.
