    Join a unique summer school co-organized by the Origins Institute at Aix-Marseille University and the Origins theme of the Institut de Physique du Globe de Paris. This interdisciplinary program offers both foundational and cutting-edge insights into the formation and evolution of the inner Solar System, with a focus on terrestrial planets and the asteroid belt. Through a dynamic blend of lectures by renowned experts and interactive roundtable discussions, participants will explore key topics such as cosmochemistry, planetary dynamics, disk processes, impacts, and surface composition. This is your opportunity to engage with leading scientists, deepen your understanding, and contribute to the conversation about our Solar System\u2019s origins.<\/p>\n\n\n\n

    2. D\u00e9c\u00e8s d’Avishai Dekel<\/h3>\n\n\n\n

    C’est avec une grande tristesse que nous vous faisons part du d\u00e9c\u00e8s d’Avishai Dekel, professeur de physique \u00e0 l’Universit\u00e9 H\u00e9bra\u00efque de J\u00e9rusalem.<\/p>\n\n\n\n

    Avishai \u00e9tait non seulement un grand nom de l’astrophysique ; il incarnait aussi une pr\u00e9sence immense tant sur le plan personnel que professionnel, par sa personnalit\u00e9 g\u00e9n\u00e9reuse qui a profond\u00e9ment marqu\u00e9 celles et ceux qui ont eu le privil\u00e8ge de le conna\u00eetre. Il \u00e9tait reconnu pour ses contributions fondamentales \u00e0 la cosmologie et \u00e0 la formation des galaxies, notamment pour ses travaux tr\u00e8s cit\u00e9s sur le r\u00f4le de la r\u00e9troaction des supernovae sur l’\u00e9volution des galaxies, la d\u00e9termination des param\u00e8tres cosmologiques, l’alimentation des galaxies par des \u00ab courants de gaz froid \u00bb issus de la toile cosmique, la \u00ab compaction \u00bb des galaxies, les \u00ab instabilit\u00e9s violentes de disque \u00bb et plus r\u00e9cemment les \u00ab flamb\u00e9es d’\u00e9toiles sans r\u00e9troaction \u00bb dans l’Univers primordial. Ces termes, invent\u00e9s ou d\u00e9velopp\u00e9s par Avishai, font aujourd’hui partie du vocabulaire courant dans le domaine de la formation et de l’\u00e9volution des galaxies. Toujours curieux et profond\u00e9ment passionn\u00e9 par son travail, Avishai est rest\u00e9 scientifiquement actif jusqu’\u00e0 la fin ; son dernier article a \u00e9t\u00e9 soumis quelques jours \u00e0 peine avant son d\u00e9c\u00e8s.<\/p>\n\n\n\n

    Avishai a re\u00e7u de nombreuses distinctions, dont le prix Landau des Arts et des Sciences, la chaire de professeur invit\u00e9 Miller de l’Universit\u00e9 de Californie \u00e0 Berkeley, et la Chaire d’excellence internationale Blaise Pascal \u00e0 l’\u00c9cole Normale Sup\u00e9rieure de Paris. Il avait de nombreux liens avec la communaut\u00e9 astrophysique fran\u00e7aise.<\/p>\n\n\n\n

    Au-del\u00e0 de ses publications et de ses r\u00e9alisations scientifiques, Avishai laisse aussi un h\u00e9ritage vivant \u00e0 travers les nombreux \u00e9tudiants, chercheurs post-doctoraux et collaborateurs qui ont eu le privil\u00e8ge de travailler \u00e0 ses cot\u00e9s.<\/p>\n\n\n\n
