Earth, Planets and Space, 2022 Solar radiation pressure (SRP) is an extremely critical perturbative force that affects the GNSS satellites’ precise orbit determination (POD). Its imperfect modelling is one of the main error sources of POD, whose magnitude is even to10−9 m/s2.

Di-nuclear molecular states in oblate-oblate system [PDF]
Physics Letters B, 1994 Abstract Narrow resonances in heavy-ion scattering of 28 Si + 28 Si are studied as an example of oblate-oblate di-nuclear systems. By the use of the molecular model, a stable configuration of the system is found to be an equator-equator touching one, due to the oblate shape of the 28 Si nuclei.

Open Astronomy, 2019 This paper aims to study the effect of the triaxiality and the oblateness as a special case of primaries on the locations and stability of the collinear equilibrium points of the elliptic restricted three body problem (in brief ERTBP).

The collinear equilibrium points in the restricted three body problem with triaxial primaries
Open Physics, 2018 The perturbed restricted three body problem has been reviewed. The mass of the primaries are assumed as triaxial. The locations of the collinear points have been computed. Series forms of these locations are obtained as new analytical results.

On the Stability of L4,5 in the Relativistic R3BP with Oblate Secondary and Radiating Primary
Advances in Astronomy, 2015 We consider a version of the relativistic restricted three-body problem (R3BP) which includes the effects of oblateness of the secondary and radiation of the primary. We determine the positions and analyze the stability of the triangular points.

Advances in Astronomy, 2015 This paper investigates the existence of resonance and nonlinear stability of the triangular equilibrium points when both oblate primaries are luminous. The study is carried out near the resonance frequency, satisfying the conditions ω1=ω2, ω1=2ω2, and ...

Results in Physics, 2018 In the framework of the relativistic R3BP, we examine the effects of oblateness of the primary body and radiation pressure of the secondary on the positions and stability of the triangular points L4,5.

Journal of Mathematics, 2013 The oblateness and the photogravitational effects of both the primaries on the location and the stability of the triangular equilibrium points in the elliptical restricted three-body problem have been discussed.

Estimating the Oblateness of Dark Matter Halos Using Neutral Hydrogen Velocity Dispersion
The Astrophysical Journal Letters, 2023 We derive the oblateness parameter q of the dark matter halo of a sample of gas-rich, face-on disk galaxies. We have assumed that the halos are triaxial in shape but their axes in the disk plane ( a and b ) are equal, so that q = c / a measures the halo ...
