Light Curve and Fourier Transform of SDSS J001245.60+143956.4. Top: Phased-folded light curve for the new pulsating low-mass WD SDSS J001245.60+143956.4. The light curve was folded to the highest-amplitude pulsational period of about P = 347 s. The solid red line indicates a sinusoidal fit, depicted for a better visualisation of the variation. Bottom: FT for the same star. The horizontal dashed red line indicates our detection limit, and the spectral window for each case is depicted as an inset plot.
