Eclipsing binaries with candidate CP stars
Photometry in the Geneva systems and radial velocities are used to determine the fundamental parameters of three eclipsing binaries, two of which having been classified as... -
C-rich stars IR and UBVRI photometry
A study of circumstellar dust shells (CDS) around carbon stars is presented. This study is based on the analysis of the 1-100{mu}m broad-band spectra of 23 objects which have... -
UBVRIcJHKL photometry in Lup
In a recent study, some 130 new weak-line T Tauri stars (WTTS) have been discovered in the Lupus star forming region (SFR). Some of these stars are seen projected onto regions... -
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... -
