BV Photometric Observations of the Dwarf Novae DX And and AR And

Abstract

We report photometric observations of the intranight variability of the dwarf novae DX And and AR And in two bands (B and V) on a few nights in late October 2022. The observations are performed with the 50/70 cm Schmidt telescope of the National Astronomical Observatory Rozhen. The results indicate that both stars exhibit intranight variability with amplitude 0.15 mag in B and V bands on a time scale of ∼ few hours. Combining our data and GAIA distances we find for the mass donor in DX And spectral type K1V, and for the mass donor in AR And -- K7V-M0V. The data are available upon request from the authors and on Zenodo.
