Undiscovered stars learned?

"This new star was detected by NASA’s telescope, the Transiting Exoplanet Satellite Survey (TESS). Normally, this telescope looks for exoplanets by watching for the periodic dimming of a star’s light as a planet passes in front of it. This is called the transit method. … The research team describes the star as “the prototype of a new class of obliquely pulsating stars…” and are excited to continue to learn more."
