Resumen:
In this work, we analyze a sample of six symbiotic systems without previous studies in the near infrared range, using data obtained with GEMINI / GNIRS in medium resolution. Our rst objective is tocharacterize the cold stellar component by examining the CO absorption bands that arise in the K-band. We will use the Kurucz models to t these spectra and determine the stellar physical parameters. We also aim to add these results to those published by Marchiano et al. (2015) using spectra taken with OSIRIS to build an atlas of symbiotic stars. We emphasize the importance of expanding the previous sample, since the number of symbiotic objects with spectroscopic observations in the K-band is currently quite scarce.
