MOST photometry of the RRd Lyrae variable AQ Leo: two radial modes, 32 combination frequencies and beyond
MOST photometry of the RRd Lyrae variable AQ Leo: two radial modes, 32 combination frequencies and beyond
Highly precise and nearly uninterrupted optical photometry of the RR Lyrae star AQ Leo was obtained with the MOST (Microvariability & Oscillations of STars) satellite over 34.4 days in February-March 2005. AQ Leo was the first known double-mode RR Lyrae pulsator (RRd star). Three decades after its discovery, MOST observations …
