Unresolved triples in the open cluster NGC 2437 (M 46) confirmed by the KMOS VVVX-GalCen Spectroscopic Survey
D. Minniti, T. Palma, C. O. Obasi +31
Recent optical and near-IR photometric databases like Gaia data release 3 (DR3) and the VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey allow the exploration of…
Unveiling hidden companions in post-common-envelope binaries: A robust strategy and uncertainty exploration
Cristian A. Giuppone, Luciana V. Gramajo, Emmanuel Gianuzzi +3
Some post-common-envelope binaries are binary stars with short periods that exhibit significant period variations over long observational time spans. These eclipse timing variation…
Automated classification of eclipsing binary systems in the VVV Survey
I. V. Daza-Perilla, L. V. Gramajo, M. Lares +4
With the advent of large-scale photometric surveys of the sky, modern science witnesses the dawn of big data astronomy, where automatic handling and discovery are paramount. In thi…
Taking a break: paused accretion in the symbiotic binary RT Cru
A. Pujol, G. J. M. Luna, K. Mukai +10
Symbiotic binaries sometimes hide their symbiotic nature for significant periods of time. There is mounting observational evidence that in those symbiotics that are powered solely…
Ca II Triplet Spectroscopy of Small Magellanic Cloud Red Giants. V. Abundances and Velocities for 12 Massive Clusters
M. C. Parisi, L. V. Gramajo, D. Geisler +4
We aim to analyze the chemical evolution of the Small Magellanic Cloud adding 12 additional clusters to our existing sample having accurate and homogeneously derived metallicities.…
Unveiling short period binaries in the inner VVV bulge
E. Botan, R. K. Saito, D. Minniti +5
Most of our knowledge about the structure of the Milky Way has come from the study of variable stars. Among the variables, mimicking the periodic variation of pulsating stars, are…
A hundred new eclipsing binary system candidates studied in a near-infrared window in the VVV survey
L. V. Gramajo, T. Palma, D. Minniti +4
We present the first results obtained from an extensive study of eclipsing binary (EB) system candidates recently detected in the VISTA Variables in the Vía Láctea (VVV) near-infra…
Monte Carlo estimation of the probability of causal contacts between communicating civilisations
Marcelo Lares, José Funes, Luciana Gramajo
In this work we address the problem of estimating the probabilities of causal contacts between civilisations in the Galaxy. We make no assumptions regarding the origin and evolutio…
New variable stars discovered in the fields of three Galactic open clusters using the VVV Survey
Tali Palma, Dante Minniti, Istvan Dékány +5
This project is a massive near-infrared (NIR) search for variable stars in highly reddened and obscured open cluster (OC) fields projected on regions of the Galactic bulge and disk…
A catalogue of Large Magellanic Cloud star clusters observed in the Washington photometric system
Tali Palma, Luciana V. Gramajo, Juan J. Clariá +3
The main goal of this study is to compile a catalogue including the fundamental parameters of a complete sample of 277 star clusters (SCs) of the Large Magellanic Cloud (LMC) obser…
Probing the Large Magellanic Cloud's recent chemical enrichment history through its star clusters
Tali Palma, Juan J. Clariá, Doug Geisler +2
We present Washington system colour-magnitude diagrams (CMDs) for 17 practically unstudied star clusters located in the bar as well as in the inner disc and outer regions of the La…
SED analysis of class I and class II FU Orionis stars
Luciana V. Gramajo, Javier A. Rodón, Mercedes Gómez
FU Orionis stars (FUORS) are eruptive pre-main sequence objects thought to represent quasi-periodic or recurring stages of enhanced accretion during the low-mass star-forming proce…
