1990ApJ...352..587C PERIODS AND LIGHT CURVES OF 16 CEPHEID VARIABLES IN IC 1613 NOT COMPLETED BY BAADE GEORGE CARLSON AND ALLAN SANDAGE The Observatories of the Carnegie Institution of Washington Received 1989 May 3; accepted 1989 September 25 ABSTRACT New periods and light curves are presented for 16 of the faintest Cepheids in IC 1613 which had not been finished by Baade. Magnitudes have been reduced to Freedman's new photometric scale. The P-L relation is extended to periods of 2 days using these new data. Comparison of the total Cepheid data now available in IC 1613 with the data in LMC shows no significant slope difference in the two P-L relations for periods of less than 10 days despite the lower metallicity of the young stars in IC 1613. Fifty new faint Cepheid candidates have been found in IC 1613 by blinking plates not used for this purpose by Baade. Most of these stars will have probable periods of less than 2 days, which will eventually permit an extension of the P-L relation in IC 1613 to fainter magnitudes when the photometry and period determinations are completed. Subject headings: galaxies: individual (IC 1613) - galaxies: Local Group - stars: Cepheids
