Stellar Continuum (part I)

Introduction to the stellar continuum of the stars with examples.

Several concepts are introduced and/or reviewed from previous courses such us: stellar flux, brightness, and (apparent/absolute) magnitudes. We discussed the -distance module- as a consequence of the dependence of the measured flux on intrinsic luminosity (L) and distance of the stars (d). 

We introduced the concept of colors of stars and its connection to temperature. We ended with the description of a black body as a very good approximation to the continuum spectrum of a star.
