Variable Stars Discipline: EducationA star is called a variable star if its apparent brightness as seen from Earth changes over time. There are two basic types of variable stars: intrinsic variables, whose luminosity actually changes, and extrinsic variables, whose apparent changes in brightness are due to changes in the amount of their light that can reach Earth. A star could be an intrinsic variable because it periodically swells and shrinks.Tags: binary starspulsating variableeruptive variableintrinsic variableextrinsic variable
The binary properties of massive stars The physics of star formation remains an outstanding problem within astrophysics. This problem is particularly acute for the production of OB stars (with masses in excess of 20 times that of the Sun); where the apparent brevity of the process (<100,000 yrs) and the presence of significant extinction (>>30 visual magnitudes) due to their birth clouds, make observations of high mass protostars highly challenging.
