I-band photometry of the quiescent black hole X-ray nova GROJ0422+32=V518 Per: modelling of the orbital light curve and estimation of the black hole mass
A. Cherepashchuk, T. Khruzina, K. Atapin
We present new photometric observations of the X-ray nova GROJ0422+32 (V518 Per) carried out in the I band over 14 nights in 2020 -- 2023. We had to revise the orbital period o…
