d = 1 / p
... A quick glance at the night sky will tell you that different stars have different brightnesses. But how much of that effect is due to the fact that some stars are further away, and how much is due to certain stars being intrinsically brighter? If we know the distances from parallax, we can remove th ...

Mass and composition determine most of the properties of a star
... The diameters of stars range from as little as 1/10 the Sun’s diameter to hundreds of times larger. The mass of stars can be from less than 1/100 to 20 or more times that of our Sun. Stars over 50 times the Sun’s mass are extremely rare. Our Sun is a medium sized star. ...

AST 112 – Activity #4 The Stellar Magnitude System
... The stellar magnitude system ranks stars according to their brightnesses. The original idea came from the ancient Greek scientist Hipparchus (c. 130 B.C.), who proclaimed the brightest stars to be of the first “magnitude”, the next brightest of the second magnitude, and so on down to 6th magnitude f ...
