After subtracting the bestfitting eclipsing binary model, the residuals were analyzed to determine the pulsation properties.
en.wikipedia.org The longer the pulsation period, the more luminous the star.
en.wikipedia.org It has been proposed that this short-term behaviour is due to non-radial pulsations, fast rotational modulation, or the presence of a lower-mass companion.
en.wikipedia.org It can detect luminosity variations associated with acoustic pulsations of stars.
en.wikipedia.org During each pulsation cycle, the temperature of the star varies by.
