The origins of these objects remain poorly understood, and likely involve a combination of many different processes relevant to star and planet formation. Direct imaging surveys of young star-forming regions have already found hundreds of high-mass rogue planets, though it remains an ongoing theoretical challenge to determine what fraction represent ejected planets as opposed to aborted stellar embryos. Meanwhile, upcoming microlensing missions such as the Nancy Grace Roman telescope are poised to vastly increase our sample of free-floating planets at masses extending to Earth-mass and below, opening a new window into their origin and demographics.<\/p>\n\n\n\n<p>Rogue Worlds 2 is a 3-day workshop designed to bring together researchers at the forefront of different aspects of the study of free-floating planets, including microlensing (ground- and space-based), direct imaging, and modeling of stellar and planetary dynamics. The format of the workshop is designed to promote discussion and foster collaboration, bringing together researchers across a wide array of fields to make new progress on our understanding of rogue worlds and the systems they leave behind.<\/p>\n\n\n\n<p>Transmis par Herv\u00e9 Bouy<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">12.

A comprehensive knowledge of planetary composition is essential to understand planet formation and evolution. Since planetary interiors are largely inaccessible, their compositions must often be inferred from atmospheric observations. In this context, deciphering the complex mechanisms linking a planet\u2019s interior to its atmosphere is a key scientific challenge. This winter school will explore these interior\u2013atmosphere interactions across a wide range of planetary environments. We will address both physical and chemical aspects of planetary evolution \u2014 from the contraction of gas giants to the effects of volcanism and outgassing on the atmospheres of rocky planets.<\/p>\n\n\n\n<p>Registration and information:&nbsp;<a href=\"https:\/\/planet-atmo-int.sciencesconf.org\/?lang=en\">https:\/\/planet-atmo-int.sciencesconf.org\/?lang=en<\/a><\/p>\n\n\n\n<p>New deadline:&nbsp;<strong>October 24th, 2025 (midnight CEST) &nbsp;<\/strong><\/p>\n\n\n\n<p>Transmis par Martin Turbet<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">13.
