UBV photometry of EG And
We present all available UBV photometry of the symbiotic binary EG And obtained during the last 10 years. The light curves display a double wave through one orbital cycle. It is... -
Geneva Photometry of HD 34798 & HD 45284
We discuss the period analysis of two variable mid-B stars that have been observed in the Geneva photometric system between 1981 and 1990. Both HD 34798 and HD 45284 are... -
CH Cyg 1991-1995 UBV-JHKLM photometry
We present new UBV-JHKLM photoelectric photometry of the symbiotic binary CH Cyg covering the period 1991-1995, which extend our monitoring started in 1978. The large and highly... -
Evolution models of elliptical galaxies. II.
In this paper we present new chemo-spectro-photometric models of elliptical galaxies in which infall of primordial gas is allowed to occur. They aim to simulate the collapse of... -
Hyades binaries
We have derived accurate and homogeneous lithium abundances in 49 Main Sequence binary systems belonging to the Hyades open cluster by using a deconvolution method to determine... -
Liller 1
We carried out VRI and Gunn z observations of the obscured globular cluster Liller 1. The cluster is so reddened (A_V_=~9.0) that it is at the detection limit in V. The RGB in I... -
uvby-Hbeta photometry of Eta Car 1992-94
We present and analyze two seasons of intense photometric monitoring in the Stroemgren uvbyH{beta} system of {eta} Carinae (October 1992-August 1994). The luminous blue variable... -
UBV Photometry of phi Per
A detailed analysis of a very rich collection of spectroscopic and photometric observations of the bright Be star {phi} Per (HR 496, or HD 10516, 2000 position: 01 43 39.4 +50... -

Light variations on Beta Pic
We have analyzed {beta} Pictoris photometric measurements obtained from La Silla by the Geneva Observatory from 1975 to 1992. These data show evidence of variations in the... -

BV(RI)c light curves of BS Com
We derive the basic physical parameters of the field double-mode RR Lyrae star BS Com from its observed periods and the requirement of consistency between the pulsational and... -
