SUMMARY:colloquium Mikako Matsuura - Dust and molecules in dying stars
DESCRIPTION:There is a large debate about how dust grains have been accumulated in the interstellar medium (ISM) of galaxies. One of the major sources of dust grains into the ISM  is evolved stars\, such as AGB stars\, red supergiants and supernovae (SNe). On the other hand\, fast-expanding SN blast waves could be so efficient that theoretical models predict that almost entire ISM dust grains ejected by stars can be wiped off by SN explosion. There are still uncertainties in dust evolution in the ISM. We present several results about studies of AGB stars\, planetary nebulae (PNe) and SNe in my talk. The first part is GAIA studies of AGB stars\, showing the distribution of local dust output from AGB stars. The second part is studies of dust in PN\, using JWST\, indicating the final re-processing of dust grains before they are integrated into the ISM. Finally\, JWST observations capture how dust grains are destroyed by SN blast waves in Supernova 1987A.

SUMMARY:colloquium Giovanni Poggiali: Looking from micro- to macro-scale: how the exploration of the Solar System can benefit from laboratory experiments on analog and returned samples
DESCRIPTION:The exploration of the Solar System’s rocky surfaces of planets and minor bodies using remote sensing benefits from multiple sources of data: from ground-based observations\, to orbiter and lander flybys\, to returned samples of extraterrestrial material. However\, the more data we acquire\, the more it becomes clear that our current interpretation techniques (both laboratory and modelling)\, although improving\, are still not sufficient to fully understand our observations. Indeed\, the interpretation of remote sensing data could not be separated from intensive laboratory work\, which provides a powerful tool for revealing the surface physical state and composition of rocky surfaces. The analysis of complex mixtures of analogous materials remains one of the key laboratory investigations to support remote sensing interpretation\, but it is also one of the most challenging experiments\, especially when multiple components are used. This talk gives a general overview of the main results from the literature on the efforts to use laboratory data to interpret infrared observations. Some new measurements on the mixing effect of different grain sizes and dark materials are also presented.

SUMMARY:colloquium Ettore Perozzi - The Asteroid Hazard: from Awareness to Operations
DESCRIPTION:Over the last 30 years\, monitoring the NEO (Near-Earth Object) population has undergone a change of\nparadygm. Started as a research activity mainly focussed in investigating the challenging dynamical\nbehaviour of these small solar system bodies (needing high-accuracy orbit determination\, close encounter\nmodelling\, impact monitoring)\, it is now carried out routinely by dedicated centers at agency level (e.g. the\nNASA and ESA Planetary Defence Offices). The NEAR rendezvous with Eros (February 2000) inaugurated the\nin-situ exploration of NEOs which\, to date\, encompasses sample return missions and the successful\nDart/LICIAcube deflection experiment. Infrared orbiting obervatories are planned for further fostering the\nNEO discovery rate. Finally\, the asteroid hazard has attracted the growing concern of governmental\nintitutions\, which have established their own programmes and roles\, reaching up to the United Nations\n(UNOOSA) for global coordination. The transition to a ground- and space-based operational system is\ntherefore nearing. Within this framework\, the (sometimes difficult) interaction between the many souls of\nPlanetary Defence – science\, technology\, civil protection\, commercial exploitation – is discussed in an\nhistorical perspective.
