NONVstAR

About

"Variable stars are in the center of attention of most scientific studies (e.g. Gaia Collaboration et al. (2019). Cepheid variables and their Period-Luminosity-relation (Leavitt & Pickering (1912)), for example, allowed us to start constructing a distance ladder which helped to explore large regions of the Universe. However, it is important to not loose sight of non-variable stellar objects, as we can use them as calibration targets, deriving standard fluxes and radial velocities, and have a way to calibrate stellar formation and evolutionary tracks. Additionally non-variable stars can be used as photometric calibration of effective temperatures and metallicity." [link to paper]

With this webtool you can find all essential information about the selected star, download .fits files directly and create an interactive light curve plot (Lomb-Scargle periodogram) and compare it with a pregenerated frequency-power spectrum plot.
