How spectral fittings of stellar clusters are affected by the wavelength range used

Star clusters (SCs) are excellent laboratories to test stellar populations, as well as to determine their key properties such as age (t) and metallicity ([Fe/H]). For distant (extragalactic) SCs only integrated spectra are available, and one of the most powerful methods to study these properties is...

Los cúmulos estelares (CE) son excelentes laboratorios para estudiar las poblaciones estelares, y para determinar sus propiedades principales como edad (t) y metalicidad ([Fe/H]). Para CE distantes (extragalácticos) se dispone sólo de espectros integrados, y uno de los métodos más poderosos para estudiar estas propiedades es a través de la síntesis espectral. Aunque este método es de gran utilidad, existen varias limitaciones de los resultados basados en la síntesis espectral. Aplicamos esta técnica a espectros de cúmulos estelares de la Nube Mayor de Magallanes para diferentes regiones espectrales usando el código Starlight, a fin de explorar la dependencia de los parámetros de las poblaciones estelares con el rango espectral adoptado.
