The uvbyHbeta Metallicity Calibration for G and K Dwarfs
B. A. Twarog, L. C. Vargas, B. J. Anthony-Twarog
The metallicity dependence of the primary indices of the uvby photometric system for cooler dwarfs (Teff ~ 6500 K to 5000K) is investigated. The data base for the analysis is compo…
vbyCaHbeta CCD Photometry of Clusters. VIII. The Super-Metal Rich, Old Open Cluster NGC 6791
B. J. Anthony-Twarog, B. A. Twarog, L. Mayer
CCD photometry on the intermediate-band vbyCaHbeta system is presented for the metal-rich, old open cluster, NGC 6791. Preliminary analysis led to [Fe/H] above +0.4 with an anomalo…
uvbyCa H beta CCD Photometry of Clusters. VII. The Intermediate-Age Anticenter Cluster Melotte 71
B. A. Twarog, S. Corder, B. J. Anthony-Twarog
CCD photometry on the intermediate-band uvbyCa H beta system is presented for the anticenter, intermediate-age open cluster, Melotte 71. Restricting the data to probable single mem…
Extended Stromgren Photoelectric Photometry in NGC 752
Barbara J. Anthony-Twarog, Bruce A. Twarog
Photoelectric photometry on the extended Stromgren system (uvbyCa) is presented for 7 giants and 21 main sequence stars in the old open cluster, NGC 752. Analysis of the hk data fo…
uvbyCaHbeta CCD Photometry of Clusters. V. The Metal-Deficient Open Cluster NGC 2243
B. J. Anthony-Twarog, J. Atwell, B. A. Twarog
CCD photometry on the intermediate-band uvbyCaHbeta system is presented for the metal-deficient open cluster, NGC 2243. Restricting the data to probable single members of the clust…
uvbyHbeta CCD Photometry of Clusters. IV. Solving the Riddle of NGC 3680
B. J. Anthony-Twarog, B. A. Twarog
CCD photometry on the uvbyCaHbeta system is presented for the open cluster, NGC 3680. Restricting the data to probable cluster members using the CMD and the photometric indices alo…
