We present HST UV observations of the high-inclination low mass X-ray binary AC211 (X2127+119), which is located in the globular cluster M15 (NGC 7078). We have discovered a C P Cygni profile in this system, which confirms the existence of an o

SOPHIE is a new fiber-fed echelle spectrograph in operation since October 2006 at the 1.93-m telescope of Observatoire de Haute-Provence. Benefiting from experience acquired on HARPS (3.6-m ESO), SOPHIE was designed to obtain accurate radial velociti

We report the discovery of a new bright (V$\sim$12.6) cataclysmic variable star identified with the ROSAT X-ray source RX J1643.7+3402. Spectroscopic and photometric observations show it to be a novalike variable sharing some of the characteristics o

TAROT (Telescope a Action Rapide pour les Objets Transitoires) is a two step project whose goal is the observation of short optical transient sources, primarily GRBs. As a first step, a CCD camera will be used at the focus of a 25 cm telescope, able

This paper describes the optical identification and the X-ray light curve of an ultrashort transient X-ray source, GS 1354 - 64, discovered on February 13, 1987 by the All Sky Monitor (ASM) on onboard Ginga satellite. The data obtained by ASM are sup

X-ray, optical and ultraviolet observations of massive binary systems have yielded basic information on the masses and radii of the massive early-type companions and the masses and moments of inertia of the neutron stars. We briefly review the eviden

Analysis of optical spectra of HD102567 (HEN 715), the optical counterpart of the X-ray source 4U1145-61 is presented. Estimates of the star's rotation velocity, inclination angle, distance and envelope characteristics are given. Some consequences of

La campagne d'observation internationale de CAL 83, en 1984, a permis la determination sans aucune ambiguite de la periode de cette binaire RX. Elle est de 1.04 jours avec une modulation sinusoidale de 0,22 mag autour d'une valeur moyenne V=16.87. Oc
