Abstract:
The CoRoT - Convection Rotation and Planetary Transits - space mission
provides a unique opportunity to monitor RR Lyrae stars with excellent
time-sampling, unprecedented photometric precision, and a long time
base of 150 days.
The pulsation characteristics of RR Lyrae stars rely on robust
physics, but we still lack a firm quantitative understanding of the
physical mechanisms driving the Blazhko modulation and the long-term
changes in their pulsation behavior. We use the high- precision space
data of an unknown RR Lyrae star CoRoT ID 0105288363 observed during a
second long run centered on the Galaxy -LRc02-, to improve our
understanding of the pulsation properties of RR Lyrae stars.
Description:
The CoRoT data were corrected using a jump and trend filtering code.
We applied different period-finding techniques including Period04,
MuFrAn, PDM, and SigSpec. Amplitude and phase modulation were
investigated using an analytical function method as well as
traditional O-C diagrams.
