TYC 3877 02198 1 is a new multiperiodic RR Lyrae variable star. Besides clearly
expressed first-overtone radial pulsations, it shows at least two non-radial modes
according to ROTSE1 data
(Wozniak et al. 2004; also see http://skydot.lanl.gov/nsvs).
These observations were analyzed using the period-search software developed by Dr.
V.P. Goranskij for Windows environment.
The following light elements are used to plot the phased light curves:
The frequency f4 (3.2678 c/d, see the Figure) is probably spurious. RR Lyrae variables with equidistant triplets of frequencies (two non-radial frequencies around the first-overtone mode) have been known for some time in the LMC (Alcock et al. 2000). J-H = 0.084 (2MASS), B-V = 0.411 (Tycho2). The coordinates were drawn from the Tycho-2 catalog. | ||||||||||||||||||||
