Atlas of Vega: 3850 -- 6860 Ã
Hyun-Sook Kim, Inwoo Han, G. Valyavin +3
We present a high resolving power ( / = 90,000) and high signal-to-noise ratio (700) spectral atlas of Vega covering the 3850 -- 6860 Ã wavelength range. The atlas…

V. Shimansky, N. A. Sakhibullin, I. Bikmaev +4
We present the results of spectroscopic-- and orbit--sampled photometric observations of the faint UV-excess object PG 2200+085. The optical CCD photometry observations of this obj…
Discovery of The New WZ Sge Star, SDSS J080434.20+510349.2
E. Pavlenko, S. Yu. Shugarov, N. A. Katysheva +13
We present the results of photometric observations of SDSS J080434.20+510349.2 in its low state and during an outburst and spectroscopy during the outburst. We found such peculiari…
MASTER OT J172758.09+380021.5: a peculiar ER UMa-type dwarf nova, probably a missed nova in the recent past
E. Pavlenko, T. Kato, K. Antonyuk +15
A CCD photometry of the dwarf nova MASTER OT J172758.09 +380021.5 was carried out in 2019 during 134 nights. Observations covered three superoutbursts, five normal outbursts and qu…
