Apsidal precession of orbits about an oblate planet

open access: yesAstronomical Journal, 1981
It is noted that expressions for the apsidal precession rates to second order on J2 appear in the literature in at least three apparently mutually contradictory forms. The expressions are reconciled by accounting for subtle differences in the definitions of orbital elements.

Circular Rydberg states of helium atoms or helium-like ions in a high-frequency laser field

open access: yesOpen Physics, 2021
In the literature, there were studies of Rydberg states of hydrogenic atoms/ions in a high-frequency laser field. It was shown that the motion of the Rydberg electron is analogous to the motion of a satellite around an oblate planet (for a linearly ...

Computation of the perturbed locations of L1 for all Sun-Planet RTBP systems with oblate primaries

open access: yesResults 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.

Constraining the oblateness of transiting planets with photometry and spectroscopy [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Rapid planetary rotation can cause the equilibrium shape of a planet to be oblate. While planetary oblateness has mostly been probed by examining the subtle ingress and egress features in photometric transit light curves, we investigate the effect of oblateness on the spectroscopic Rossiter–McLaughlin (RM) signals. We found that
