The DOMENG project has introduced the Domain Engineering Process to the space community as a first stone on the roadmap to build a model-based and reused- oriented software production system, based on the analysis and modelling of the Space domain. At the current stage, the first iteration of the domain engineering process is close to an end and

Fullerenes, the carbon molecules with 60 and 70 atoms, were recently detected in a series of planetary nebulae, in protoplanetary nebulae and in other astrophysical objects. The detection and the quantitative determination of these molecules was made possible by the measurement of their reference infrared spectra and the relative molar extinction

Near-infrared spectroscopy was conducted to search for molecular material around 40 post-AGB stars. We present the detection of molecular emission lines of H2, 1-0S(1) at 2.122 microns and 2-1S(1) at 2.248 microns in 11 of the post-AGB observed. In addition, Brγ lines at 2.166 microns also were detected in these objects. To investigate the

We present high spatial resolution ($\approx60$--90 milliarcseconds) images of the molecular hydrogen emission in the Planetary Nebula (PN) NGC~2346.The data were acquired during the System Verification of the Gemini Multi-Conjugate Adaptive Optics System (GeMS) + Gemini South Adaptive Optics Imager GSAOI).At the distance of NGC~2346, 700 pc, the

Many complex organic molecules and inorganic solid-state compounds have been observed in the circumstellar shell of stars (both C-rich and O-rich) in the transition phase between Asymptotic Giant Branch (AGB) stars and Planetary Nebulae (PNe). This short (~102-104 years) phase of stellar evolution represents a wonderful laboratory for

We present the results of a five-month spectroscopic monitoring campaign of two radio loud quasars, PKS 1217 + 023 and PKS 1302 - 102. There is a pronounced lack of variability in 1302 - 102 apart from a possible small change in the continuum level near the end of the monitoring period, but 1217 + 023 underwent a 20 percent continuum decrease in
