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

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

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

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

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

Conjecture on the Origin of the Solar System

Liu Taixiang

Abstract: This paper briefly describes the principle of the formation of the solar system, and explains the cause of the Titius-Bode law, the rotational angular momentum and revolutionary momentum of a celestial body.

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

SOME CHARACTERISTICS OF COSMIC MICROWAVE BACKROUND RADIATION

Michał Marek

Abstract: Data gathered by the Planck i.e. maps of temperature Cosmic Microwave Background (CMB) have been used for analysis of a number of counts of the CMB as a function of their temperature by IDL software. Recently I presented a histogram made by Fv software (Marek 2018). Power-law slope for reasonable range of data is alpha=1.81.

IS THE UNIVERSE A SELF-ORGANIZED CRITICALITY SYSTEM?

Michał Marek

Abstract: Sandpile Paradigm was proposed by Bak, Tang and Wiesenfeld (Bak et al. 1987) to explain simple model of Self-Organized Criticality (SOC). When the piles fall on the sandpile (input driver), we will see, that at some critical point (reaching adequate angle of response), sand will slide down to get the saturation phase.

A proposed new gravitational redshift function to the theoretical model of Morris-Thorne wormholes

Raul Isea

Abstract: This work introduces a new gravitational redshift function to the Morris-Thorne wormhole model that is defined as Φ(r)≡r_0/r ln⁡(r/r_0 ) with spherical symmetry and stabilized by phantom energy.
