Using Observations of Solar Vector Magnetic Field from Dual View Points to Remove the 180∘ Ambiguity
Liu, Rui; Zhou, Ru-yun; Wang, Yu-ming +3 more
With Solar Orbiter (SO) being put into successful operational observation, solar magnetic observation has entered the era of remote sensing from dual view points. In this paper, we carried out a simulation of correcting the 180∘ ambiguity of transverse magnetic field with magnetograms from dual view points using an analytical formula as…
A Revisit to the Optical Starlight Polarization Catalogue by Heiles: Distance Update
Meng, Mei-niang; Sun, Xiao-hui
Starlight polarization serves one of the powerful tools to study magnetic fields in the Galactic interstellar medium. Heiles catalogue contains polarization information for 9286 stars, and is by far the biggest. This catalogue has been extensively used to study the magnetic fields. However, the distance parameters of the stars in this catalogue ar…
