El estudio de las estrellas en la era del big data
Main Article Content
Resumen
Se aborda el problema de correlacionar modelos teóricos con espectros electromagnéticos observados en estrellas masivas en el contexto del gran volumen de información astronómica disponible en la actualidad. Se analizan las características de los códigos de atmósferas estelares y el proceso de modelado y ajuste del espectro observado de una estrella, los recursos de cómputo que se consumen en dicho proceso, así como el problema de los modelos desechados o almacenados en forma no estructurada. Se concluye que en el siglo XXI la forma de realizar investigación astronómica ha cambiado radicalmente al incorporar el enfoque big data y los observatorios virtuales.
