Therefore, magnetic field configurations with a constant twist are now being employed in fits. A model of a force-free magnetic field configuration with an arbitrarily given twist distribution in a cylinder and its
relative helicity per unit length are presented. It is applied to a core-envelope model recently suggested in studies of twist in magnetic clouds.Workplace Astronomical Institute Contact Radka Svašková, bibl@asu.cas.cz, Tel.: 323 620 326 Year of Publishing 2020 Electronic address https://doi.org/10.1051/0004-6361/201935216
