Stellar atmospheric parameters and chemical abundances of about 5 million stars from S-PLUS multi-band photometry
C. E. Ferreira Lopes, L. A. Gutiérrez-Soto, V. S. Ferreira Alberice +30
Context. Spectroscopic surveys like APOGEE, GALAH, and LAMOST have significantly advanced our understanding of the Milky Way by providing extensive stellar parameters and chemical…
A statistical study of lopsided galaxies using random forest
Valentina Fontirroig, Facundo A. Gomez, Marcelo Jaque Arancibia +2
Lopsided galaxies are late-type galaxies with a non-axisymmetric disk due to an uneven distribution of their stellar mass. Despite being a relatively common perturbation, several q…
Application of Convolutional Neural Networks to time domain astrophysics. 2D image analysis of OGLE light curves
N. Monsalves, M. Jaque Arancibia, A. Bayo +4
In recent years the amount of publicly available astronomical data has increased exponentially, with a remarkable example being large scale multiepoch photometric surveys. This wea…
The Fourth S-PLUS Data Release: 12-filter photometry covering square degrees in the southern hemisphere
Fabio R. Herpich, Felipe Almeida-Fernandes, Gustavo B. Oliveira Schwarz +68
The Southern Photometric Local Universe Survey (S-PLUS) is a project to map sq deg of the sky using twelve bands (seven narrow and five broadbands). Observations are per…
The largest metallicity difference in twin systems: high-precision abundance analysis of the benchmark pair Krios & Kronos
P. Miquelarena, C. Saffe, M. Flores +7
Aims.We conduct a high-precision differential abundance analysis of the remarkable binary system HD 240429/30 (Krios and Kronos, respectively), whose difference in metallicity is o…
Disentangling the origin of chemical differences using GHOST
C. Saffe, P. Miquelarena, J. Alacoria +8
Aims. We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD 138202 + CD-30 12303. For the first time, we suggest ho…
