SUMMARY:colloquium - Alice Borghese: The zoo of isolated neutron stars
DESCRIPTION:Neutron stars have shown diverse characteristics\, leading us to classify them into different classes. In this talk\, I will focus on the observational properties of isolated neutron stars: from magnetars\, the strongest magnets we know of\, to central compact objects\, the so-called anti-magnetars\, stopping by the rotation-powered pulsars and X-ray dim isolated neutron stars. Moreover\, I will show you how some sources have exhibited features straddling those of different groups. I will then finish with some considerations on possible evolutionary links between neutron star families.

SUMMARY:Colloquium Antonella Barucci - The JAXA sample return  MMX (Martian Moon eXploration) mission
DESCRIPTION:The JAXA MMX mission will be launched in 2026 to Martian system to carry out three years observations of the Martian moons\, and to bring back  to Earth in 2031 samples (>10 g) from Phobos. The spacecraft will arrive at Mars system in 2027\, injected into Phobos co-orbit\, to observe Phobos and monitor Mars’ atmosphere. Deimos will be also explored by several  fly-bys. \nThe mission is devoted to study the origin of Martian moons\, to enlarge the knowledge of the Martian system and to assess the possibility of Martian life\,.\nThe major goals of the mission  are to decipher the origins of the Martian moons and constrain processes for planetary formation and material transport in the region connecting the inner and outer Solar System. From the Martian moon Phobos\, MMX will investigate the transport of water and organic materials across the Solar System and explore how life and habitable environments were created. The mission will clarify the driving mechanism of the transition of the Mars-moon system and add new knowledge to the evolution history of Mars. \nAn imager spectrometer MIRS (MMX Infrared Spectrometer) has been requested to our team at LESIA-Paris Observatory to accomplish several of the science objective of the mission.\nThe status of art of the mission will be presented.

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.
