Abstract:
We present a collection of more than 4000 UBVRI and uvby differential
photometric measurements of the newly-discovered 12th-magnitude
southern Delta Scuti star GSC 08613-02122. The star has a main
pulsation period of about 4 hours with an amplitude of 0.05m in the V
band. The pulsation amplitude is variable, and the O-C diagram reveals
the existence of a long P∼29.5-day cycle, which possibly results
from the beating of the main pulsation frequency with a nearby
frequency.
Description:
The differential magnitudes of GSC 08613-02122 are presented in
oca.dat, and saao.dat.
eso.dat gives the uvby photometry of GSC 08613-02122 and NGC 3293-20.
