In each of the three panels, the spectra of the resolved components of the LHS 1070 triple system (Leinert et al 1994) -observed with the Faint Object Spectrograph (FOS) on the left (Leinert et al 2000) and with NICMOS on HST on the right -are compared to models of various authors. Black: observed spectra.…”

Abstract.Within the next few years, several instruments aiming at imaging extrasolar planets will see first light. In parallel, low mass planets are being searched around red dwarfs which offer more favorable conditions, both for radial velocity detection and transit studies, than solar-type stars. We review recent advancements in modeling the stellar to substellar transition. The revised solar oxygen abundances and cloud models allow to reproduce the photometric and spectroscopic properties of this transition to a degree never achieved before, but problems remain in the important M-L transition characteristic of the T eff range of characterisable exoplanets.

“…In any comparison with theory, age therefore enters as an unwelcome free parameter, and reduces the diagnostic value of those two binaries. A few additional systems are being followed, such as LHS 1070 (Leinert et al 1994(Leinert et al , 2001) and Gl 494 (Beuzit et al 2004), but identifying additional late-M dwarfs binaries with periods under ∼10 years remains critically important.…”

“…IONIC is available in two versions, that cover the H and the K bands respectively. No extensive calibrator observations have been collected and made public yet with IONIC, and we will restrict ourselves in Leinert et al (2003). d K-band magnitude (goal) for 5σ fringe detection in 100 ms on UTs equipped with MACAO (Strehl = 0.5).…”

Abstract. The ESO Very Large Telescope Interferometer (VLTI) is one of the leading interferometric facilities. It is equipped with several 8.2 and 1.8 m telescopes, a large number of baselines up to 200 m, and with several subsystems designed to enable high quality measurements and to improve significantly the limits of sensitivities currently available to long-baseline interferometry. The full scientific potential of the VLTI can be exploited only if a consistent set of good quality calibrators is available. For this, a large number of observations of potential calibrators have been obtained during the commissioning phase of the VLTI. These data are publicly available. We briefly describe the interferometer, the VINCI instrument used for the observations, the data flow from acquisition to processed results, and we present and comment on the volume of observations gathered and scrutinized. The result is a list of 191 calibrator candidates, for which a total of 12 066 observations can be deemed of satisfactory quality. We present a general statistical analysis of this sample, using as a starting point the angular diameters previously available in the literature. We derive the general characteristics of the VLTI transfer function, and its trend with time in the period 2001 through mid-2004. A second paper will be devoted to a detailed investigation of a selected sample, aimed at establishing a VLTI-based homogeneous system of calibrators.
