Astrophysics is the branch of science that deals with the physics of the universe, as well as the physical properties (luminosity, density, temperature, and chemical composition) of celestial objects like stars, galaxies, and also the interstellar space, and their interactions.
Astroparticle physics, also known as particle astrophysics, is a branch of natural philosophy that studies elementary particles of astronomical origin and their relation to Astrophysics, Cosmic ray physics, astronomy, Cosmology and Particle physics. It is quite a new field arising at the interaction of particle physics, astronomy, astrophysics, detector physics, relativity, solid state physics, and cosmology. Partly driven by the invention of neutrino oscillation, the field has undergone fast development, both in theory and experiments. The field of astroparticle physics has developed from the field of Optical physics. The detector technology has advanced the field of astrophysics which involved topics, like mechanics, electrodynamics, thermodynamics, plasma physics, nuclear physics, relativity, and particle physics. Particle physicists found astrophysics necessary due to difficulty in producing particles with comparable energy to those found in space.
Uses of astrophysics are observatory astronomy and theoretical astrophysics which are concerned with finding out the measurable implications of physical models and figure out the observational consequences of those models.They mainly focus on the areas: stellar dynamics and evolution; galaxy formation and evolution; magnetohydrodynamics; large-scale structure of matter in the universe; origin of cosmic rays; general relativity and physical cosmology, including string cosmology and astroparticle physics.
Journal of Astrophysics and aerospace Technology (JAAT) is an Open Access journal includes a wide range of fields in its discipline. Scholarly open access journal aims to publish most complete and reliable source of information on the discoveries and current developments in the mode of original articles, review articles, case reports, short communications, etc. Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. Moreover, stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may coalesce about them. Consequently, the study of the birth, life, and death of stars is central to the field of astronomy.
