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.

The stellar thermal wind as a consequence of oblateness [PDF]
, 2023 In many rotating fluids, the lowest-order force balance is between gravity, pressure, and rotational acceleration ('GPR' balance). Terrestrial GPR balance takes the form of geostrophy and hydrostasy, which together yield the terrestrial thermal wind ...

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.

From solar to stellar oblateness
, 2009 International audienceRotation, and more precisely differential rotation, have a major impact on the internal dynamics of stars (and the Sun) and induce many instabilities driving the transport of angular momentum.

SunSketcher: a Citizen Science network project for the heliophysics big year
Frontiers in Astronomy and Space SciencesSunSketcher is an innovative program of eclipse observations that utilizes a network of smartphones along the path of totality to identify and geolocate the precise contact times via their definitive signature–Baily’s Beads–and hence place meaningful ...

Elements of this book, Oblation: Essays, Parables, Paradoxes, defy reason. They do so for good reason. Much of what we do, much of what we think, is oblation: sacrifice, offering, to something or someone. The root of “oblation” is “to draw near” or “to dwell in.” It refers to what is brought unto the altar, literal or proverbial — the profoundest ...

Computation of the perturbed locations of L1 for all Sun-Planet RTBP systems with oblate primaries
Results in Physics, 2019 The location of the equilibrium point ΔL1 in the restricted three body problem with oblate primaries is investigated. The zonal harmonic coefficients are retained up to the fourth harmonic coefficient of both primaries.
