Resumen
Reportamos las mediciones del sistema binario espectroscópico Algol, realizadas con el espectrógrafo Espartaco-2 en el observatorio astronómico de la Universidad de los Andes en Bogotá. A partir de las velocidades radiales medidas en varias épocas, inferimos los parámetros orbitales. Nuestros resultados son similares a los valores encontrados en la literatura.
