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.

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 ...

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 ...

Luminosity variation in the extended one-zone RR Lyrae model [PDF]
Serbian Astronomical Journal, 2005 The Stellingwerf one-zone stellar model is extended by assuming, a slow and uniform rotation that leads to a very small oblateness of the star. The matter in the core-surrounding shell is supposed to consists of a mixture of ideal gas and radiation. This

Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e
The Astronomical JournalPlanets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

Physical Review D, 1998 The spherically symmetric hedgehog ansatz used in the description of the skyrmion is believed to be inadequate for the rotational states such as the nucleon (I=J=1/2) and the Delta (I=J=3/2) due to centrifugal forces. We study here a simple alternative: an oblate spheroidal solution which leads to lower masses for these baryons.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Slow Rotation for the Super-puff Planet Kepler-51d
The Astrophysical Journal LettersSuper-puffs are low-density planets of unknown origin and composition. If they form by accreting nebular gas through a circumplanetary disk, one might expect super-puffs to be spinning quickly. Here, we derive upper limits on the rotational oblateness of

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.
