Irregular dwarf galaxy KK 230: A relatively young galaxy at the periphery of the local group?
Kinematics and Physics of Celestial Bodies - Tập 24 - Trang 137-144 - 2008
T. N. Yakobchuk
We present some results of the photometric analysis of the stellar population of the irregular dwarf galaxy KK 230 on the basis of the archive database of the Hubble space telescope. The color index-magnitude diagram for KK 230 gets to magnitude 27 m in the V and I bands, and it comprises stellar populations of various ages. The age of the youngest main-sequence stars is 3.2 × 107 yr. These stars ... hiện toàn bộ
Radial velocities of the photospheric matter in a solar flare with matter ejection
Kinematics and Physics of Celestial Bodies - Tập 26 - Trang 26-35 - 2010
N. N. Kondrashova, M. N. Pasechnik
We present results of a study of photospheric horizontal motions at the initial and main phases of the solar flare which happened on September 4, 1990, near the solar limb. The flare was accompanied by matter ejection. Spectra of the flare were obtained using the AZU-26 horizontal solar telescope at the MAO NAS (Terskol observatory). We found variations of the matter motion velocity’s value and di... hiện toàn bộ
Các Đặc Điểm Nhận Dạng của Bão Từ và Bão Ionospheric từ Ngày 21 đến 24 tháng 12 Năm 2016 Dịch bởi AI

Các cơn bão mặt trời đi kèm với các vụ phun trên bề mặt mặt trời, hiện tượng phun khối lượng khí quyển và dòng chảy nhanh gây ra những rối loạn đáng kể trong hệ thống Mặt trời – môi trường liên hành tinh – từ quyển – điện quyển – bầu khí quyển – Trái Đất (các địa quyển nội tại). Do đó, các cơn bão không gian địa lý với sự tương tác động qua lại giữa các cơn bão từ, điện quyển, khí quyển và điện xu... hiện toàn bộ

Determination of zenith tropospheric path delay for the Ukrainian permanent GPS stations using observation data for GPS weeks 1236–1399
Kinematics and Physics of Celestial Bodies - Tập 27 - Trang 59-61 - 2011
O. A. Khoda
Observations of GPS satellites for GPS weeks 1236–1399 at permanent stations located in Ukraine and Eastern Europe were processed with the Bernese GPS Software package ver. 4.2 in the GPS Data Analysis Center of the Main Astronomical Observatory of the National Academy of Sciences of Ukraine. Obtained values of the tropospheric path delay for the Ukrainian permanent GPS stations are presented.
Molecules in the early universe
Kinematics and Physics of Celestial Bodies - Tập 33 Số 6 - Trang 255-264 - 2017
Novosyadlyj, B., Sergijenko, O., Shulga, V. M.
The formation of first molecules, negative Hydrogen ions, and molecular ions in a model of the Universe with cosmological constant and cold dark matter is studied. The cosmological recombination is described in the framework of modified model of the effective 3-level atom, while the kinetics of chemical reactions is described in the framework of the minimal model for Hydrogen, Deuterium, and Heliu... hiện toàn bộ
Comparison of joint and individual catalogs of radio source positions
Kinematics and Physics of Celestial Bodies - Tập 27 - Trang 197-203 - 2011
S. O. Litvin
Comparison is given of joint and individual catalogs of radio source positions created in preparation of ICRF2. Differences between catalogs are shown, and the “external” evaluation of their accuracy is carried out.
Kamchatka Meteoroid Effects in the Geomagnetic Field
Kinematics and Physics of Celestial Bodies - - 2022
L. F. Chernogor
The data acquired at ten geomagnetic observatories (Paratunka, Magadan, Yakutsk, and Khabarovsk (the Russian Federation); Memambetsu, Kanoya, and Kakioka (Japan); Cheongyang (Republic of Korea); Shumagin and College (USA)) during the Kamchatka meteoroid event of December 18, 2018, and on the reference days of December 17 and 19, 2018, have been used to analyze temporal variations in the geomagneti... hiện toàn bộ
Bipolar molecular outflow in IRAS 17233-3606
Kinematics and Physics of Celestial Bodies - Tập 32 - Trang 276-282 - 2016
O. V. Antyufeyev, V. M. Shulga, I. I. Zinchenko
The high-mass star-forming region IRAS 17333-3606 has been mapped in the 13CO (J = 2–1) and C18O (J = 2–1) lines in the submillimeter wavelength range using the APEX (Chile) radio telescope. The analysis of the low-velocity part of the molecular outflow has been carried out, and the main parameters of the outflow have been determined. We have used a novel approach for calculating parameters of the... hiện toàn bộ

Theoretical and Observed Signs of Excitation of Small-Scale Magnetic Fluctuations in the Depth of the Sun
Kinematics and Physics of Celestial Bodies - Tập 39 - Trang 342-355 - 2023
V. N. Krivodubskij, N. M. Kondrashova
An actual problem today is the search for observed evidence of the existence of deep small-scale magnetic fields of the Sun. In this regard, the authors analyzed the theoretical criterion for separating the contributions to the solar surface magnetism of two qualitatively different mechanisms of a small-scale dynamo, the action of which is hidden in the depths of the solar convection zone (SCZ), p... hiện toàn bộ
