Astronomy compels the soul to look upwards and leads us from this world to another.

Solar Physics

Solar physics is the branch of astrophysics that specialises in the study of the Sun and stars. These articles cover types of stars, the life cycle of stars, spectroscopy and observations of our Sun.

 

Birth of a Star
12th November 2008Solar Physics
In this article we will look at the birth of a star, stellar nurseries, star stuff and introduce the main sequence which describes the life of a star.
Luminosity of Stars
22nd April 2008Solar Physics
In astronomy, luminosity is the total amount of energy radiated by a star, galaxy, or another astronomical object per unit time. It is related to the brightness, which is the luminosity of an object in a given spectral region. In SI units luminosity is measured in joules per second or watts.
Flux
21st April 2008Solar Physics
Flux is a term used to describe the brightness of a star and is a measure of the total energy from an object per unit area over time. Flux calculations are used to calculate luminosity, a more meaningful representation of a star's brightness.
