    "abstract": "The electronic structure of vortices in a type II superconductor is analyzed\nwithin the quasi-classical Eilenberger framework. The possible origin of a\nsixfold ``star\u0027\u0027 shape of the local density of states, observed by scanning\ntunneling microscope experiments on NbSe$_2$, is examined in the light of the\nthree effects; the anisotropic pairing, the vortex lattice, and the anisotropic\ndensity of states at the Fermi surface. Outstanding features of split parallel\nrays of this star are well explained in terms of an anisotropic $s$-wave\npairing. This reveals a rich internal electronic structure associated with a\nvortex core.",
