Masses and Orbital Constraints for the OGLE-2006-BLG-109Lb,c Jupiter/Saturn Analog Planetary System
D. P. Bennett, S. H. Rhie, S. Nikolaev +70
We present a new analysis of the Jupiter+Saturn analog system, OGLE-2006-BLG-109Lb,c, which was the first double planet system discovered with the gravitational microlensing method…

Improving the mass determination of Galactic Cepheids
G. Bono, W. P. Gieren, M. Marconi +2
We have selected a sample of Galactic Cepheids for which accurate estimates of radii, distances, and photometric parameters are available. The comparison between their pulsation ma…

On the pulsation mode identification of short-period Galactic Cepheids
G. Bono, W. P. Gieren, M. Marconi +1
We present new theoretical Period-Radius (PR) relations for first overtone Galactic Cepheids. Current predictions are based on several sequences of nonlinear, convective pulsation…
