Descripción
We have obtained for the first time 2.10 - 2.45 micron infrared spectra of soft X-ray transient V404 Cygni. We determine a 95 percent confidence upper limit to the fraction of light arising from the accretion disc of 14 percent. The effect this has on the mass of the compact object, determined from modelling the infrared ellipsoidal variations, is to reduce its mass to at most 10 M(solar mass).

    The RIZ & UBV visible spectrographs of the ANDES instrument, which are foreseen to be installed at the Extremely Large Telescope, require to be under a very stable high vacuum and at an extremely stable temperature of 1mK to reach the radial velocity goal of 10cm/s RMS over a 10-year period. The baseline design, integration and first analyses of
