New Results of Radiation Study on Board TGO ExoMars in 2018–2023
Mitrofanov, I.; Golovin, D.; Kozyrev, A. +13 more
The article provides a brief description of the Liulin-MO dosimeter, which is part of the FREND (Fine Resolution Epithermal Neutron Detector) device installed on the TGO (Trace Gas Orbiter) spacecraft of the ExoMars-2016 mission. Since April 2018, TGO has been operating in orbit around Mars. Data are presented on the radiation environment in the o…
Spectral Signs of Simultaneous Sublimation Activity and the Appearance of a Dust Exosphere on Eight Asteroids of the Main Belt Near Perihelion
Shcherbina, M. P.; Busarev, V. V.; Savelova, A. A. +1 more
In December 2020, at the 2-m telescope of the Terskol branch of the Institute of Astronomy, we carried out spectrophotometric observations in the range of ~0.36-0.95 µm of nine asteroids of the Main Belt (19 Fortuna, 52 Europa, 102 Miriam, 177 Irma, 203 Pompeja, 250 Bettina, 266 Aline, 379 Huenna, and 383 Janina), which were near perihelia o…
Solar Flares of Various Types and Their Effect on the Formation of Interplanetary Medium Disturbances
Belov, A. V.; Livshits, M. A.; Osokin, A. R.
Factors that could produce the statistical relationship observed between the duration of transient processes on the Sun and the power of corresponding disturbances of the interplanetary medium are investigated. Uniform data on the soft X-radiation of more than 50000 flares made it possible to study their number distribution according to duration i…
