UNDERSTANDING VARIABLE STARS
Percy JR.
Las estrellas variables son aquellas que van modificando la intensidad de su brillo. Esta variabilidad en el brillo puede ser debida a procesos geométricos tales como la rotación, eclipses de estrellas cercanas, o procesos físicos como vibraciones, o explosiones cataclísmicas. En cualquiera de esos casos, la variación en la intensidad del brillo proporciona una información de interés para el estudio de las propiedades de las estrellas, y de los procesos internos o externos que están asociados a esa variación. En esta monografía, ilustrada con gráficas, dibujos y fotografías, se ofrece una introducción panorámica al fenómeno.
