Outliers: multicolour photometry guiding the search for evolved binary systems in the globular cluster 47 Tucanae
Fabiola Campos, I. Pelisoli, S. Kamann +11
We use Hubble Space Telescope multicolour photometry of the globular cluster 47 Tucanae to uncover a population of 24 objects with no previous classification that are outliers from…
White Dwarfs in the Metal-Rich Open Cluster NGC 6253
Elizabeth J. Jeffery, Fabiola Campos, Alejandra Romero +1
We have obtained 53 images with the filter and 19 images with the filter, each with 600-second exposures of the super metal rich open cluster NGC 6253 with the Gemini-South…
A comparative analysis of the observed white dwarf cooling sequence from globular clusters
Fabíola Campos, P. Bergeron, A. D. Romero +8
We report our study of features at the observed red end of the white dwarf cooling sequences for three Galactic globular clusters: NGC\,6397, 47\,Tucanae and M\,4. We use deep colo…
The age-metallicity dependence for white dwarfs
A. D. Romero, F. Campos, S. O. Kepler
We present a theoretical study on the metallicity dependence of the initialtofinal mass relation and its influence on white dwarf age determinations. We compute a grid of evo…
Extracting parameters from Colour-Magnitude Diagrams
C. Bonatto, F. Campos, S. O. Kepler +1
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 H…
Multichromatic colour-magnitude diagrams of the globular cluster NGC 6366
Fabíola Campos, S. O. Kepler, C. Bonatto +1
We present multichromatic isochrone fits to the colour-magnitude data of the globular cluster NGC 6366, based on Hubble Space Telescope Advanced Camera for Surveys/Wide Field Chann…
