Catalog of variable stars in the WD 0009+501 and GRW +708247 fields based on photometric survey data on transiting exoplanets
O. Ya. Yakovlev, A. F. Valeev, G. G. Valyavin +15
We present a catalog of 150 variable stars, including 13 stars with exoplanet candidates. 37 stars were identified as variables for the first time. As a result of a 2.5-year photom…
Doppler confirmation of TESS planet candidate TOI1408.01: grazing transit and likely eccentric orbit
G. A. Galazutdinov, R. V. Baluev, G. Valyavin +16
We report an independent Doppler confirmation of the TESS planet candidate orbiting an F-type main sequence star TOI-1408 located 140 pc away. We present a set of radial velocities…
Eight exoplanet candidates in SAO survey
O. Ya. Yakovlev, A. F. Valeev, G. G. Valyavin +15
Here we present eight new candidates for exoplanets detected by the transit method at the Special Astrophysical Observatory of the Russian Academy of Sciences. Photometric observat…
Fundamental parameters and evolutionary status of the magnetic chemically peculiar stars HD 188041 (V1291 Aquilae), HD 111133 (EP Virginis), and HD 204411. Spectroscopy versus interferometry
A. Romanovskaya, T. Ryabchikova, D. Shulyak +4
The determination of fundamental parameters of stars is one of the main tasks of astrophysics. For magnetic chemically peculiar stars, this problem is complicated by the anomalous…
Magnetic field and radial velocities of the star Chi Draconis A
Byeong-Cheol Lee, D. Gadelshin, Inwoo Han +13
We present high-resolution spectropolarimetric observations of the spectroscopic binary Chi Dra. Spectral lines in the spectrum of the main component Chi Dra A show variable Zeeman…
A study of the photometric variability of the peculiar magnetic white dwarf WD1953-011
G. Valyavin, K. Antonyuk, S. Plachinda +14
We present and interpret simultaneous new photometric and spectroscopic observations of the peculiar magnetic white dwarf WD1953-011. The flux in the V-band filter and intensity of…
