We present photometric and spectroscopic studies of the white dwarf (WD)populations in the intermediate-age open clusters NGC 6633 and NGC 7063 as partof the ongoing Lick-Arizona White Dwarf Survey (LAWDS). Using wide-field CCDimaging, we locate 41 candidate WDs in the two cluster fields: 32 in NGC 6633,and 9 in NGC 7063. Spectroscopic observations confirm 13 of these candidates tobe bona-fide WDs. We describe in detail our Balmer line fitting technique forderiving effective temperatures and surface gravities from optical DA WDspectra and apply the technique to the 11 DA WDs in the sample. Of these, onlytwo DA WDs are at the cluster distance moduli, one in each cluster. Two moreDAs lie 0.75 mag foreground to NGC 6633, raising the possibility that these aredouble degenerate systems in the cluster. If nearly equal-mass binaries, bothof these systems likely have combined masses above the Chandrasekhar limit. OneDB WD is found to be consistent with membership in NGC 6633, which would makethis the third confirmed He-atmosphere WD in an open cluster, though furtherdata are needed to confirm cluster membership. The WD consistent withmembership in the cluster NGC 7063 has a low mass (~0.4 Mo), suggesting it maybe a He-core WD resulting from close binary evolution. Three of the elevenhydrogen-atmosphere WDs in this study are observed to have Ca II absorption;the number of DAZs in this study is consistent with previous observations that~25% of field WDs are DAZs.Comment: 16 pages, 10 figures.
