A Search for Isolated Cool Magnetic White Dwarfs
Abstract
We present the ongoing results of our search for new highly evolved (cool) isolated magnetic white dwarfs (MWDs) with extremely strong magnetic fields. The search was carried out using the broadband photopolarimeter of the 1 meter telescope of SAO RAS. Observations were conducted in circular polarization search mode, with typical values of -0.6% and higher in integrated light. A detailed study of 19 sources with temperatures less than 6000 K was carried out in a 100 pc volume. As a result, 3 new magnetic white dwarf candidates were found with fields of 10 MG and higher.
