Close approach maneuvers around an oblate planet

open access: yesJournal of Physics: Conference Series, 2015
There are many applications of the close approach maneuvers in astronautics, and several missions used this technique in the last decades. In the present work, those close approach maneuvers are revisited, but now considering that the spacecraft passes around an oblate planet.

Polarization of Starlight by an Unresolved and Oblate Extrasolar Planet in an Elliptical Orbit

open access: yesAstrophysical Journal, 2006
We calculate the degree of linear polarization of radiation from stars having planets that may not be resolved spatially. We assume single scattering by water and silicate particulates in the planetary atmosphere. The dilution of the reflected polarized radiation of the planet by the unpolarized stellar radiation and the effect of oblateness of the ...

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

TESS phase curve of ultra-hot Jupiter WASP-189 b★

open access: yesAstronomy & Astrophysics
Context. The thermal structures of highly irradiated ultra-hot Jupiters can deviate substantially from those of cooler hot Jupiters. For planets orbiting host stars that are rapidly rotating (and, thus, oblate), photometric light curves provide a unique ...
