Analysis of mass-luminosity curves for different subsets of binaries (both visual and eclipsing spectroscopic binaries) revealed the deviation in slopes for relatively close binaries (averaged around 3.6*10-4 light years) compare to relatively far spaced binaries (averaged around 5.6*10-3 light years). The slope for close binaries is larger, what means that for the same luminosity of the main sequence stars the determined from Kepler law gravitational mass is smaller (or gravity between stars is stronger). This observation is opposite to the MOND idea (the far the stars the higher shift from 1/r2 law to 1/r law for gravity) – that would be opposite effect. The idea of dark matter seems to be confirmed once more (as if some dark mass is hanging around the star, thus making the mass seemingly larger), but a new concept of some kind of gravity enhancement by the mass itself may also be relevant – the closer the binary the higher local concentration of mass and higher value of G in the gravity law.

Published data clearly demonstrates that an accelerating gravitational attraction between planets or between stars and planets, is not proven to exist. Behaviour between Earth and Moon is a local example. At an altitude of 800km space junk refuses to comply with the Newtonian Hypotheses and where mg = zero. Given this observation, why should gravitational acceleration reappear at 384,000km and affect the Moon. This Moon orbits via a perfect circle around a centre at 21,400km from Earth, where there is no mass. Solar System Planets display the same circular orbits about an eccentric point, measured from the Sun. With interplanetary SPACE gravity not proven to exist, Gravity Waves cannot be proven to exist, even if Black Holes do exist. Applying Electro/Magnetic Theory to “Kepler’s Laws” and to every Solar System planet and moon results in Data and Arithmetic being in full agreement with observed data. Einstein’s ‘Relativity’, without a Nobel prize, is superfluous measured against Electro/Magnetic Physics. To clarify these statements, Earth tidal data will be applied, to demonstrate that Earth tides are independent from Moons hypothetical gravity.

In this paper I have used the Schwarzschild solution for Einstein’s field equation to find the change of proper time in a gravitational field with respect to time measured by gravitationally unaffected stationary clock. The equations tells us about the nature of temporal flow or temporal velocity for any body considering gravitational effect.I have further treated the solution to find a rate of change of the temporal velocity which signifies a temporal acceleration for any varying mass body. On the second phase I have used Einstein’s time
dilation equation of special relativity to find the temporal flow of a particle moving with certain speed, neglecting the gravitational effect of the particle. Further calculations on the nature of temporal velocity reveals us a temporal acceleration for a particle with different velocities at different instant of time. I have also found equations relating to the nature of time in extreme cases
of the universe like black holes and particles like photons.

A short explanation of the differences between a cluster’s age, a star systems age and a star’s age are provided. The three are not always the same. It is claimed by the dogmatists that K2-25b is ~600 million years old with reference to the Hyades Cluster, as well as K2-25 which is the host red dwarf, all because they are in the same cluster. They have clusters, young stars and intermediate aged stars as being the same age, but clearly they are not. Explanation is provided.

In this introductory project, we have studied the about the neutron capture processes which are responsible
for the abundances of heavy elements than iron in different phases of stellar evolution.
Our main aim is to understand the distribution of isotropic abundances in our universe.
First we start with the discussion on nucleosynthesis and its types, then we discussed about the different types of neutron capture processes.
After that we provide results of the simulation which we have done using Monte Carlo method. Finally we conclude with the importance of these processes and current research status.

Sir Isaac Newton calculated the center of gravity of our solar system using his Universal Law of Gravitation and his three Laws of Motion. Since only six planets up to Saturn had been discovered during his life-time, Newton was working with insufficient data. It is necessary to make a fresh calculation of the center of gravity of our solar system using the latest available data. My calculations show that the center of gravity of our solar system is clearly outside the body of the Sun, and more likely at the center of our Earth. This hypothesis resolves many of the unsolved mysteries and paradoxes that the sun-centered universe of the Copernican heliocentric model has spawned since it was first adopted by Galileo and Kepler in the early seventeenth century.
