\abstract{Se analiza la distribución del gas molecular asociado a fuentes IRAS y 2MASS, objetos estelares jóvenes asociados a la región HII Gum 31, en base a observaciones obtenidas con el telescopio APEX, ubicado en el norte de Chile. Para llevar a cabo este estudio se utilizaron observaciones de líneas de diversos isótopos de monóxido de Carbono, CS(7-6) y HCO$^{+}$(4-3).   

Las fuentes se ubican en el borde de la región HII Gum 31 cuyo frente de choque afecta sustancialmente la morfología del medio molecular de las mismas. Las observaciones revelan que en el entorno de las fuentes hay emision molecular asociada a la nebulosa, que se evidencia en la emisión del $^{12}$CO, con pequeños grumos de alta densidad detectados en C$^{18}$O. No se han podido detectar flujos bipolares asociados a las fuentes en la zona, por lo que se podría inferir que las fuentes IR son objetos en etapas tardías de formación.
