Resumen:
G316.8-0.1 radio source (IRAS 14416-5937) presents DBS 89-90-91 as embedded clusters (Dutra et al. 2003, A&A 400, 533).This is a high mass star forming region and several studies have been performed over it. As a consequence, different distances were established:-- Caswell & Haynes 1987 (A&A 171, 261) using 5 GHz tabulate velocities of hydrogen recombination lines and proposed a distance of 2.5 kpc.-- Caswell et al. 1995 (MNRAS 272, 96) using 6.6 GHz data galactic methanol masers proposed a distance of 3.3 kpc.-- Bronfman et al. 1996 (A&AS 115, 81) using 98 GHz data and Busfield et al. 2006 (MNRAS 366, 1096) with radio observations data identified a diversity of molecular lines and maser sources proposing a distance of 2.8 kpc.-- Additionally, near and far IR observations (Vig et al. 2007, A&A 463, 175) provided photometric information about the brightest (J < 15) young star population and the properties of the dust in the region, together with some parameters regarding the interaction between the stellar and interstellar components.In this work, we performed a deep and detailed infrared study of the region of DBS 89-90-91 embedded clusters, we investigated the interstellar medium and searched Young Stellar Object candidates (YSOc) using catalogues detailed in section 2.Our main target was to better understand the properties of G316.8-0.1 HII region identifying the nature of the stellar population in this region and its interaction with the interstellar medium and distance.
