Parameteres for 88 giant variable star candidates

Our aim is to expand the sample of new types of variables reported in a previous study. These variables show a short period (PV<0.6day) and a low amplitude (AV<0.06mag.).

We first searched for variability using the generalized Lomb-Scargle and phase dispersion minimization periodograms of the sample, discarding 167 stars as non-variables. We then applied the significance test and reduced the sample to 88 giants, of which we classified 18 as possible variables, 11 as dubious, 41 as non-variables, and 18 as variables. We finally determined the cluster membership of this sample and grouped each star based on their light-curve shape.
