Spectroscopic and Photometric Study of the New Eclipsing Polar Gaia23cer

We present the results of our optical study of the eclipsing polar Gaia23cer. We analyze the orbital brightness variability in high () and low () states. The system has an orbital period min and exhibits deep eclipses with a duration s. The spectra have a red cyclotron continuum with the Zeeman H ab...

description	We present the results of our optical study of the eclipsing polar Gaia23cer. We analyze the orbital brightness variability in high () and low () states. The system has an orbital period min and exhibits deep eclipses with a duration s. The spectra have a red cyclotron continuum with the Zeeman H absorption triplet forming in a magnetic field with a strength MG. The source of emission lines has a high radial velocity semi-amplitude (km s), and its eclipse lags behind the eclipse of the white dwarf. The mass and temperature K of the white dwarf have been estimated by modelling the spectral energy distribution. The eclipse duration corresponds to a donor mass and an orbital inclination. The donor temperature was estimated to be K by modelling the elliptical variability and eclipse depth.
