Asteroid research is of global security interest, we are more afraid about any impact these asteroids on Earth. We seek through this work to provide a study the effect asteroid’s shape gravity aspect. Knowledge potential crucial bodies approaching asteroid. There range asteroid shapes consider. Some well-known such Ceres, Vesta, Iris and Oumuamua considered in study. After determining moment in...

We show that gravitational wave astronomy has the potential to inform us on quantum aspects of black holes. Based Bekenstein's quantization, we find hole area discretization could impart observable imprints signal from a pair merging holes, affecting their absorption properties during inspiral and late-time relaxation after merger. In contrast with previous results, rotation, ubiquitous in astr...

Abstract We show that a small but measurable shift in the eclipse midpoint time of eclipsing binary (EBs) stars ∼0.1 s over decade baseline can be used to directly measure Galactic acceleration Milky Way at ∼kiloparsec distances from Sun. consider contributions period drift rate dynamical mechanisms other than Galaxy’s gravitational field and reliably measured using sample Kepler EBs with orbit...

A treatment of linearized gravity with Einstein-Gauss-Bonnet interaction terms in D ≥ 5 is given in the Randall-Sundrum brane background. This Letter has outlined some interesting features of the brane world gravity and Newtonian potential correction with GB interaction term. We find that the GB coupling α renormalizes the effective four-dimensional Newton constant on the brane, and also additi...

Gravitational potential energy (GPE) is lost during convective adjustment. Using monthly mean climatological datasets, the annual mean GPE loss due to convective adjustment in the world oceans is estimated at 0.24 TW. Conversion from the mean-state GPE to eddies GPE and kinetic energy (KE) is also estimated, using the commonly accepted Gent-McWilliams scheme. Our estimate is that about 1.1TW is...

scheduling is to determine the priorities or arrange the activities to meet the needs, limitations and certain goals. because the time is always a limited resource, all activities should be scheduled to use optimally and certainly the resource. gravitational force algorithm, like other evolutionary algorithms, is inspired by nature. the effect of the gravity on the objects reciprocally and to a...
