The Lower Tauric suite (Upper Triassic) in the Kacha Anticline Uplift of mountainous Crimea     

D. I. Panov  I. V. Panchenko  V. L. Kosorukov 《Moscow University Geology Bulletin》2011,66(2):84-93

Deposits of the Lower Tauric suite (Upper Triassic) are exposed in the Kacha Anicline Uplift (Southeastern Crimea) near the source of the Bodrak River. Their rhythmostratigraphic, lithological, and paleontological charactristics are given for the first time; their tectonic position is determined and their age is specified. The principles for stratigraphic subdivision of the Tauric series are formulated.  相似文献   

The radioastronomical “time machine” effect can help the solution of the gamma ray bursts mystery     

Galina V. Lipunova  Ivan E. Panchenko  Vladimir M. Lipunov 《New Astronomy》1997,2(6):555-558

The possible low-frequency radio emission from the progenitors of gamma ray bursts can experience a delay from tens of seconds to hours on the way to the observer due to the dispersion in galactic and extragalactic plasma, and thus reach the observer as a radio afterglow of the burst. This opens a unique possibility (peculiar “time machine”) of seeing what happened at that place before the catastrophe.  相似文献   

The mechanism of supernova Ia explosion in elliptical galaxies     

V.M. Lipunov  I.E. Panchenko  M.V. Pruzhinskaya 《New Astronomy》2011,16(4):250-252

Recent observational data on the type Ia supernova rates are in excellent agreement with the earlier results of the population synthesis of binary stars and confirm that the overwhelming majority of type Ia supernovas (～99%) in elliptical galaxies form via mergers of binary white dwarfs with a total mass exceeding the Chandrasekhar limit.  相似文献   

Vertical plasma drift velocities in the polarization jet observation by ground Doppler measurements and driftmeters on DMSP satellites     

V. L. Khalipov  A. E. Stepanov  G. A. Kotova  S. E. Kobyakova  V. V. Bogdanov  A. B. Kaisin  V. A. Panchenko 《Geomagnetism and Aeronomy》2016,56(5):535-544

Vertical and horizontal plasma drifts are investigated during the polarization jet (PJ) detection in the F2 ionospheric layer based on the Doppler measurements at the Yakutsk meridian chain of subauroral ionospheric stations. It is shown that the velocities of vertical and horizontal drifts are significantly higher than the background motion during PJ observation periods. The ionospheric plasma motion direction changes from upward to downward on the polar edge of the main ionospheric trough. Doppler measurements on the DPS-4 ionosondes are compared with the simultaneous measurements of the plasma drift on the DMSP satellites during their passage near the Yakutsk meridian. The two kinds of measurements are in good agreement with each other. During the magnetic storm of June 23, 2005, by measurements of the DMSP satellites, the velocities of upward plasma flows were 1.0–1.4 km/s at a satellite altitude of 850 km. In the ionospheric F region, this speed corresponds to 150 m/s. According to satellite measurements, the westward drift velocity reached 2.5 km/s. The development of the polarization jet in the ionosphere was accompanied by a tenfold decrease in the electron density in 15–30 min.  相似文献

Daily Course of CO2 Fluxes in the Atmosphere–Water System and Variable Fluorescence of Phytoplankton during the Open-Water Period for Lake Baikal according to Long-Term Measurements     

Zavoruev  V. V.  Domysheva  V. M.  Pestunov  D. A.  Sakirko  M. V.  Panchenko  M. V. 《Doklady Earth Sciences》2018,479(2):507-510

The process of gas exchange of CO₂ in the atmosphere–water system and its relation to the daily course of variable fluorescence of phytoplankton is studied on the basis of long-term (2004–2014) measurements during the open water period for Lake Baikal. It is found that the decrease in photosynthetic activity of plankton is almost synchronous to the increase in the CO₂ flux from atmosphere to water. It follows from comparison of the spring and summer data with December measurements that the daily decrease in variable fluorescence of phytoplankton is caused by the internal daily rhythm of the photosynthetic activity of plankton.
