Astrophotometric search for massive stars in the Milky way. Confronting Random Forest predictions with available spectroscopy
N. Monsalves, A. Bayo, M. Jaque Arancibia +4
Massive stars play a significant role in different branches of astronomy, from shaping the processes of star and planet formation to influencing the evolution and chemical enrichme…
The role of bars in triggering active galactic nuclei galaxies
V. Marels, V. Mesa, M. Jaque Arancibia +4
Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies, potentially enhancing nuclear activity. However, the extent to which bars in…
Discovery of lambda Boo stars in open clusters
C. Saffe, J. Alacoria, A. Alejo +7
The origin of lambda Boo stars is currently unknown. After several efforts by many authors, no bona fide lambda Boo stars have been confirmed as members of open clusters. Their det…
Stream Automatic Detection with Convolutional Neural Network (SAD-CNN)
Alex Vera-Casanova., Nicolas Monsalves Gonzalez, Facundo A. Gómez +8
Context. Galactic halos host faint substructures, such as stellar streams and shells, which provide insights into the hierarchical assembly history of galaxies. To date, such featu…
Searching for lambda Boo stars in binary systems
J. Alacoria, C. Saffe, A. Collado +7
Our goal is to find new candidate lambda Boo stars that belong to binary systems. A detailed abundance determination of some candidates could confirm their true lambda Boo nature,…
A First Quantitative Characterization of Colombian Night Sky Through All-Sky Photometry
J. P. Uchima-Tamayo, R. Angeloni, M. Jaque Arancibia +2
Light pollution, a rapidly escalating anthropogenic phenomenon driven by the excessive and often inefficient use of artificial lighting, has profound implications for astronomy, ec…
