The simulated domain is a cube of 4 parsecs (13 light years) aside and ionization is simulated for a million years . Initially the cloud is considered with significant turbulence (the order of magnitude of the velocity fluctuations is of 4 times the speed of sound , or Mach 4). In this case, the velocity fluctuations are greater than the pressure of the ionized gas and allow turbulent bubbles to detach and form globules.<\/span><\/p>\n<p class=\"tw-data-text vk_txt tw-ta tw-text-small\" dir=\"ltr\" data-placeholder=\"Traduction\">A series of snapshot is available\u00a0<a href=\"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/wp-content\/uploads\/2014\/05\/image_turb.zip\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>French post\u00a0@ CEA\/IRFU\/SAp \u201cBy using the latest data from the Herschel Space Observatory, an international team coordinated by the Astrophysique- Service Laboratory AIM Paris Saclay (CEA-IRFU \u2013 CNRS \u2013 Universit\u00e9 Paris Diderot) has highlighted the impact of massive stars on<span class=\"ellipsis\">&hellip;<\/span> <span class=\"read-more\"><a href=\"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/?p=13\">Read more &#8250;<\/a><\/span><\/p>\n","protected":false},"author":2,"featured_media":59,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-13","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-star-formation"],"_links":{"self":[{"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/posts\/13","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=13"}],"version-history":[{"count":4,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/posts\/13\/revisions"}],"predecessor-version":[{"id":165,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/posts\/13\/revisions\/165"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=\/wp\/v2\/media\/59"}],"wp:attachment":[{"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=13"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=13"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wilder.diskstation.me\/pascal-tremblin\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=13"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
