pyUPMASK: an improved unsupervised clustering algorithm
M. S. Pera, G. I. Perren, A. Moitinho +2
Aims. We present pyUPMASK, an unsupervised clustering method for stellar clusters that builds upon the original UPMASK package. Its general approach makes it plausible to be applie…
Embedded clusters: upgrading visual and infrared photometric analysis with Gaia DR2 and ASteCA
E. E. Giorgi, G. R. Solivella, A. Cruzado +3
Embedded clusters are groups of stars which have not dispersed yet the residual of the parental cloud where they were born so getting precise distances and properties of these grou…
Sixteen overlooked open clusters in the fourth Galactic quadrant. A combined analysis of UBVI photometry and Gaia DR2 with ASteCA
G. I. Perren, E. E. Giorgi, A. Moitinho +3
Aims: This paper has two main objectives: (1) To determine the intrinsic properties of 16 faint and mostly unstudied open clusters in the poorly known sector of the Galaxy at 270$^…
New age-metallicity diagnostic diagram for the Washington photometric system
Andrés E. Piatti, Gabriel I. Perren
The age calibration of the Washington deltaT1 index is mainly used to estimate ages of star clusters older than 1 Gyr, no age-metallicity degeneracy effect is considered. We have p…
The nearby Galaxy structure toward the Vela Gum nebula
E. E. Giorgi, G. R. Solivella, G. I. Perren +1
We report on photometry and spectroscopy for MK classification purposes carried out in the fields of five open clusters projected against the Vela Gum in the Third Galactic…
