Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012 Methods for estimating the impact probability of asteroid Apophis were implemented. The probability of a collision was assessed using two methods: the Monte Carlo method, and the second one, utilizing a ratio between the interval of values of orbital ...

Orbital Parameter Determination for Wide Stellar Binary Systems in the Age of Gaia
, 2020 The orbits of binary stars and planets, particularly eccentricities and inclinations, encode the angular momentum within these systems. Within stellar multiple systems, the magnitude and (mis)alignment of angular momentum vectors among stars, disks, and ...

The Triple Pulsar System PSR B1620-26 in M4 [PDF]
, 1999 The millisecond pulsar PSR B1620-26, in the globular cluster M4, has a white dwarf companion in a half-year orbit. Anomalously large variations in the pulsar's apparent spin-down rate have suggested the presence of a second companion in a much wider ...

Design and Simulation of Stellar Occultation Infrared Band Constellation
Remote Sensing, 2022 This study provides an in-depth analysis of the characteristics of stellar occultation events. Using 10 target star sources, the influence of orbital elements on the number, duration, and distribution of stellar occultation events was simulated and ...

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019 In this paper, we study the accuracy of solving various differential equations describing the motion of large planets, the Moon and Sun. On the time interval from 31 years BC to 3969 AD, the numerical integration of Newtonian relativistic differential ...

Effects Of Direct And Indirect Solar Radiation Pressure In Orbital Parameters Of GPS Satelittes
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 In this paper we determined the variation of the Keplerian orbital elements of a GPS satellite due to the direct and indirect action of solar radiation pressure. For this study, we created a soft program to determine the Keplerian elements.
