J/AJ/114/1190 J/AJ/114/1190 NSV 09295: A double-mode RR Lyrae E Garcia-Melendo C M Clement Astron. J. 114 1190 1997 1997AJ....114.1190G Photometry, CCD Stars, variable The table lists the magnitudes of star NSV 09295 relative to the star GSC 1001.0757 which has a photovisual magnitude PAL-V1=13.43+/-0.36 according to the Guide Star Catalogue. The times listed are the Heliocentric Julian Dates at the time of mid-exposure. An analysis of more than 2000 CCD observations of the field RR Lyrae star NSV 09295 shows that the star is a double-mode RR Lyrae (RRd) variable with P_0_=0.46334d and P_1_=0.34423d. This brings the total of known field RRd stars in the Milky Way galaxy to four. These four variables are compared with the RRd stars in galactic globular clusters and with the field RRd stars in the LMC, and in the Draco and Sculptor dwarf galaxies. It appears that all known RRd stars have a metal abundance of less than [Fe/H]=-1.6. (c) 1997 American Astronomical Society.
