Extracting parameters from colour–magnitude diagrams
(2015) [Artigo de periódico]We present a simple approach for obtaining robust values of astrophysical parameters from the observed colour–magnitude diagrams (CMDs) of star clusters. The basic inputs are the Hess diagram built with the photometric ... -
Near-infrared study of new embedded clusters in the Carina complex
(2018) [Artigo de periódico]We analyse the nature of a sample of stellar overdensities that we found projected on the Carina complex. This study is based on the Two Micron All Sky Survey photometry and involves the photometry decontamination of field ... -
