Polarimetric study of the solar corona during the total solar eclipse on July 02, 2019 with a liquid crystal polarimeter

The results obtained during the total Solar Eclipse on July 2,2019, in Chile are presented together with the Eclipse K-corona Polarimeter(EKPol). The EKPol is equipped with an electro-optically modulating LiquidCrystal Variable Retarder (LCVR) for the polarimetric observation of the so-lar corona. The use of this technology has been an important ground-basedtest for the application of this technology in space-based observatories. Theusage of LCVRs in a polarization rotator configuration, allows the replacementof mechanically rotating retarders avoiding moving parts and reducing noise,failure probability, and mass. Indeed, EKPol was developed as a technologydemonstrator for the Metis coronagraph on-board Solar Orbiter. The results,from the composition of the image to the electron density map evaluation, arecompared and are consistent with what is obtained by other ground-based andspace-based instruments, and with past EKPol campaigns.
