The heliospheric current sheet (HCS) is observed as a sector boundary in the ecliptic plane, and its orientation and structure have been intensely studied. It divides the heliosphere into regions with opposite magnetic polarities. Analysis of its local structure at 1 AU let to study the HCS as a magnetic directional discontinuity supported by a current sheet (CS).
HYTARO+ is an analytical model development to evaluate the influence of the solar magnetic dipole in the topology of the local structure of the HCS. Using multipole expansion, HYTARO+ analyzes the contribution of the dipolar and quadrupolar magnetic field in the HCS. HYTARO+ deepens the study of the background magnetic field present in the analyzed current sheet crossings.
A preliminary analysis, evaluating the influence of the solar magnetic dipole in the topology of the local structure of the HCS, is summarized. The data provided by the Parker Solar Probe (PSP) and Solar Orbiter (SolO) instrumentation have allowed us to advance in the analysis of the multipole components of the IMF by performing location-dependent studies.
