What is TESS Exploration of Targets Investigated for the Nainital-Cape Survey Project about?

The Nainital-Cape Survey was initiated more than two decades ago aiming to search for and study the pulsational variability in two subclasses of chemically peculiar (CP) stars, namely the Ap and Am stars. In this paper, we present the TESS photometry of 4 targets out of the 369 sample stars observed under the survey, which were not studied before using TESS data. Our results suggest that HD34060 is a rotational variable, HD25487 is of eclipsing nature, HD15550 exhibits pulsational variability while HD48953 is a non-variable star. The diverse variability detected in the studied sources places important constraints for the study of the internal structure and evolution of the CP stars in the presence of surface inhomogeneity, magnetic field, rotation and pulsation.
