What reading level is The Stars: a Study of the Universe book?
To quickly assess the difficulty of the text, read a short excerpt:
The nearer a dark planet is to the star, the more likely it will be to hide its light from an ob- server at a great distance. If, for example, the planet Jupiter were nearly as large as the sun, the chances would be hundreds to one against the plane of the orbit being so nearly in the line of a distant observer that the latter would ever see an eclipse of the sun by the planet. But if the planet were close to the sun, the chances might increase to one in ten, and yet further to almost any exten...t, according to the nearness of the two bodies.
Still, we cannot set any definite limit to the period of stars of this type ; all we can say is that, as the period we seek for increases, the number of stars varying in that period must diminish. This follows not only from the reason just given, but from the fact that the longer the interval that separates the partial eclipses of a star of the Algol type, the less likely they are to be detected.
io6 VARIABLE STARS The star Beta Lyrae shows variations quite diflfer- \ ent in their nature from those of Algol, yet having a The certain analogy to them.
