Could the number of blue straggler stars help to determine the age of their parent globular cluster?

Félix Llorente de Andrés

Abstract: A recent study shows, from an empirical deduction, that the number and the presence of the blue straggler stars (BSS) in an open cluster follow a function whose components are the ratio between age and the relaxation time, ƒ, and a factor, ϖ, which is an indicator of stellar collisions plus primordial binaries. The relation [...] Read more.

Ultrasonic technology of detection of gravitational waves of neutron stars - pulsars

Chernobay Ivan Alesandrovich

Abstract: The work relates to the creation of new methods and instruments for observational astronomy, in particular to gravitational astrophysics. The ultrasonic gravitational method for obtaining information about such exotic objects as neutron pulsar stars has been developed and successfully tested. Gravitational waves are detecte [...] Read more.

Basis on Negative Matter as Unified Dark Matter and Dark Energy

Yi-Fang Chang

Abstract: Based on Dirac negative energy, Einstein mass-energy relation and principle of equivalence, we propose the negative matter as the simplest model of unified dark matter and dark energy. All theories are known, only mass includes positive and negative. Because there is repulsion between positive matter and negative matter, so [...] Read more.

DARK MATTER – TRANSVERSE MASS

Flavio Barbiero

Abstract: The dark matter is a mysterious kind of matter with no mass, no inertia and none of the other characteristics that we attribute to matter, but for the fact that it exerts a force that prevents the stars of the arms of the spiral galaxies to disperse into space. A force that, to achieve this result, should decrease not with [...] Read more.

ON THE ORIGIN OF MOON AND CONTINENTS

Flavio Barbiero

Abstract: All astronomical bodies originate inside clouds of gas and dust, therefore there should be a common process that leads to their condensation. A galactic cloud normally has some turbulence and therefore a gradient of speeds from point to point. Thanks to it, a vortex originates that rakes the material of the surrounding clou [...] Read more.

Implications of detecting the Axion-Like Particles in Astro-Particle Physics

K K Singh

Abstract: Axions and axion like particles in general are consequences of the extensions of the standard model in particle physics. Axions have been proposed as hypothetical pseudo-scalar particles in particle physics to solve the strong Charge-Parity problem using quantum chromodynamics. These particles are also proposed to be an att [...] Read more.
