Spectroscopic and photometric study of the new eclipsing polar Gaia23cer

A. I. Kolbin, E. P. Pavlenko, V. Yu. Kochkina +11

We present the results of the optical study of the new eclipsing polar Gaia23cer. We analyzed the brightness variability of the polar in high ($\langle r \rangle \approx 16.5\mathr…

The Nature of the Emission Spectrum of NGC 7793 P13: modeling the atmosphere of the donor star

A. S. Vinokurov, A. E. Kostenkov, K. E. Atapin +1

We continue to study the ultra-luminous X-ray source NGC 7793 P13 in the optical range. In this work, we are testing the model of a spherically symmetric wind atmosphere of the don…
