Jupiter's orbit and alignment relative to the galaxy is the physical basis of periodic variations of gravitational constant G and the length of day
P Guynn - 2021 - hal.science
Anderson et al. analyzed measurements of gravitational constant G, and found a periodic
variation that matched both the frequency and phase of length of day (LOD) variations …

[SITAT][C] A MOND model applied to the rotation curve of galaxies
ACM Ciqueira, GA Carvalho, PH Faccin… - International Journal of …, 2025 - World Scientific
In this work, we propose a modified Newton dynamics (MOND) model to study the rotation
curves of galaxies. The model is described by an arc-tangent interpolating function and it fits …
