ResumoCataclysmic variables (CVs) are stellar binary systems composed of a white dwarf star (WD) that accretes matter from a late-type main sequence companion via an accretion disc. The magnetic Cataclysmic Variables (mCVs) harbours WDs with strong magnetic fields and are classified either as polars, whose B > 107G prevents the formation of the disc, or as intermediate polars (IPs) with B ∼ 107G, where an internally truncated disc may exist. In this work, we present the analysis of extensive, time-resolved spectroscopic, photometric and polarimetric data of the polar 1RXSJ174320.1- 042953 (=RXJ1743) obtained at the SOAR and OPD telescopes. This object was selected as a candidate in a project to identify new mCVs from the Catalina Real-Time Transient Survey - CRTS - and from previously known X-ray sources. We also present a modelling of the photometric and polarimetric data with the CYCLOPS code, in order to investigate the geometry and physics of the accretion structure close to the WD. Our photometric data yield a non-eclipsing lightcurve and an orbital period of 0.08659 days consistent, within the uncertainties, with the period found in the literature. No stable periodicity related the spin of an unsynchronized WD primary is present in the data, which would otherwise indicate an IP nature for this system. The polarimetric data reveal strong and modulated circular polarization at the 45% level, besides less intense linear polarization. The optical spectrum is typical of polars, with no lines from the secondary component. The He II 4686 ˚A and Balmer emission-line radial velocities are modulated with the orbital period. In conclusion, our observational follow-up establishes RXJ1743 as a polar, with an orbital period close to the lower edge of the CVs period gap.
