Un nouvel article, issu du travail de l’\u00e9quipe international \u00ab\u00a0Magnetic helicity\u00a0\u00bb<\/a> de l’ISSI (International Space Science Institute, Berne, Suisse), vient d’\u00eatre accept\u00e9 dans le journal The Astrophysical Journal.

Cet article s’int\u00e9resse \u00e0 la m\u00e9thode de calcul de l’h\u00e9licit\u00e9 nomm\u00e9 \u00ab\u00a0Twist number method\u00a0\u00bb (TN) d\u00e9velopp\u00e9 par le Dr. Yang Guo, chercheur \u00e0 l’Universit\u00e9 de Nanjing. Cette m\u00e9thode ne calcule pas directement l’h\u00e9licit\u00e9 magn\u00e9tique mais mesure tout d’abord l’enroulement relatif des lignes de champ magn\u00e9tique et en d\u00e9duit dans un second temps l’h\u00e9licit\u00e9. Il s’agit dans cet article de comparer les r\u00e9sultats de cette m\u00e9thode sur diff\u00e9rents jeux de donn\u00e9es avec ceux obtenus avec un calcul direct de l’h\u00e9licit\u00e9 magn\u00e9tique (tels qu’avec les m\u00e9thodes de mesure test\u00e9es dans le premier article<\/a> de l’\u00e9quipe de l’ISSI). Nous en profitons aussi pour tester la m\u00e9thode TN dans diff\u00e9rentes situations afin d’en tester les limites.<\/p>\n

Ce travail r\u00e9sulte d’une collaboration de longue haleine avec le Dr. Yang Guo. Ce dernier avait pass\u00e9 une partie de sa th\u00e8se dans notre \u00e9quipe. Pour ce travail le Dr. Guo a pass\u00e9 un s\u00e9jour d’un mois dans notre laboratoire gr\u00e2ce au financement d’un poste temporairement vacant du conseil scientifique de l’Observatoire de Paris.<\/p>\n","protected":false},"excerpt":{"rendered":"
