Large-Scale Disturbances of the Solar Wind According to Spacecraft Radio Transmission Data from the Mars Express and Local Measurements on the Wind Spacecraft
Efimov, A. I.; Smirnov, V. M.; Chashei, I. V. +1 more
The results of experiments on radio sounding of near the Sun plasma by the signals of the Mars Express Mars satellite are presented. In the region of heliocentric distances of the proximate point of the line of sight of 8–13 solar radii, frequency fluctuations of transmission radio signals were measured. During the experiments sharp increases in t…
A Search for Low-amplitude Periodic Brightness Variations in HD 168 443
Bondar', N. I.; Shlyapnikov, A. A.
The paper presents the results of studying light curves of the star HD 168443 obtained from the ground-based and space photometric observations within the ASAS, KWS surveys, and the Hipparcos mission from 1990 to 2020. During 30 years of observations, the average annual brightness of the star remained constant within the measurement errors, the me…
