Abstract

The classical Be star NW Serpentis (HD 168797) is part of the CoRoT field and has long been studied photometrically and is known to have multi-periodic pulsational modes. Such pulsations are thought to be a way to generate the Be equatorial circumstellar disk. In an earlier survey, we identified this star as a possible non-radial pulsator and a known B
