A new empirical metallicity calibration for Vilnius photometry
S. Bartasiute, S. Raudeliunas, J. Sperauskas
We present a new calibration of the seven-color Vilnius system in terms of [Fe/H], applicable to F-M stars in the metallicity range -2.8<[Fe/H]<+0.5. We employ a purely empirical a…

Studies of Variability in Proto-Planetary Nebulae: II. Light and Velocity Curve Analyses of Iras 22272+5435 and 22223+4327
Bruce J. Hrivnak, Wenxian Lu, Julius Sperauskas +3
We have carried out a detailed observational study of the light, color, and velocity variations of two bright, carbon-rich proto-planetary nebulae, IRAS 22223+4327 and 22272+5435.…
