Open cluster age calibration from colour-magnitude morphological indices using Gaia DR3 data
F. A. Ferreira, J. F. C. Santos, W. J. B. Corradi +2
Star clusters are crucial for understanding how stars evolve. Their colour-magnitude diagrams show the effects of stellar evolution of approximately coeval objects with the same ch…
New routes for PN destruction and formation in the ISM via neutral-neutral gas-phase reactions and an extended database for reactions involving phosphorus
Mateus X. Silva, Edgar Mendoza, Fábio S. L. Ferreira +5
Phosphorus plays an essential role in the chemistry of living organisms, being present in several fundamental biomolecules. The investigation of chemical reactions taking place in…
New SiS destruction and formation routes via neutral-neutral reactions and their fundamental role in interstellar clouds at low and high metallicity values
Edgar Mendoza, Samuel F. M. Costa, Miguel Carvajal +3
Among the silicon bearing species discovered in the interstellar medium, SiS and SiO stand out as key tracers due to their distinct chemistry and abundances in interstellar and cir…
The VISCACHA survey -- VII. Assembly history of the Magellanic Bridge and SMC Wing from star clusters
R. A. P. Oliveira, F. F. S. Maia, B. Barbuy +15
The formation scenario of the Magellanic Bridge during an encounter between the Large and Small Magellanic Clouds Myr ago, as proposed by -body models, would be impri…
Enlightening the dynamical evolution of Galactic open clusters: an approach using Gaia DR3 and analytical descriptions
M. S. Angelo, J. F. C. Santos, F. F. S. Maia +1
Most stars in our Galaxy form in stellar aggregates, which can become long-lived structures called open clusters (OCs). Along their dynamical evolution, their gradual depletion lea…
Glycolaldehyde formation mediated by interstellar amorphous ice: a computational study
Mateus A. M. Paiva, Sergio Pilling, Edgar Mendoza +2
Glycolaldehyde (HOCH2CHO) is the most straightforward sugar detected in the Interstellar Medium (ISM) and participates in the formation pathways of molecules fundamental to life, r…
The Si+SO collision and an extended network of neutral-neutral reactions between silicon and sulphur bearing species
Danilo R. Campanha, Edgar Mendoza, Mateus X. Silva +4
The Si+SO reaction is investigated to verify its impact on the abundances of molecules with astrochemical interest, such as SiS, SiO, SO and others. According to our results Si…
Ca II Triplet Spectroscopy of Small Magellanic Cloud Red Giants. VI. Analysis of chemical properties of the Main Body
B. J. De Bortoli, M. C. Parisi, L. P. Bassino +5
We derived radial velocities and CaT metallicity of more than 150 red giants stars in six SMC star clusters and their surrounding fields, with the instrument GMOS on GEMINI-S. The…
The VISCACHA survey -- IV. The SMC West Halo in 8D
B. Dias, M. C. Parisi, M. Angelo +18
The structure of the Small Magellanic Cloud (SMC) is very complex, in particular in the periphery that suffers more from the interactions with the Large Magellanic Cloud (LMC). A w…
Investigating Galactic binary cluster candidates with Gaia EDR3
M. S. Angelo, J. F. C. Santos, F. F. S. Maia +1
A number of stellar open cluster (OC) pairs in the Milky Way occupy similar positions in the phase space (coordinates, parallax and proper motions) and therefore may constitute phy…
SiS formation in the interstellar medium through Si+SH gas phase reactions
V. C. Mota, A. J. C. Varandas, E. Mendoza +2
Silicon monosulfide is an important silicon bearing molecule detected in circumstellar envelopes and star forming regions. Its formation and destruction routes are not well underst…
New star clusters discovered towards the Galactic bulge direction using Gaia DR2
Filipe A. Ferreira, W. J. B. Corradi, F. F. S. Maia +2
We report the discovery of 34 new open clusters and candidates as a result of a systematic search carried out in 200 adjacent fields of 1x1 square degrees area projected towards th…
Characterizing dynamical states of Galactic open clusters with Gaia DR2
M. S. Angelo, W. J. B. Corradi, J. F. C. Santos +2
In this work, we investigate the dynamical properties of 38 Galactic open clusters: 34 of them are located at low Galactic latitudes (|b| < 10) and are projected against…
The VISCACHA survey -- II. Structure of star clusters in the Magellanic Clouds periphery
J. F. C. Santos, F. F. S. Maia, B. Dias +11
We provide a homogeneous set of structural parameters of 83 star clusters located at the periphery of the Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC). The clu…
The VISCACHA survey -- deep and resolved photometry of star clusters in the Magellanic Clouds
Bruno Dias, Francisco Maia, Leandro Kerber +24
The VISCACHA (VIsible Soar photometry of star Clusters in tApii and Coxi HuguA\footnote{LMC and SMC names in the Tupi-Guarani language spoken by native people in Brazil}) Survey is…
Nearly coeval intermediate-age Milky Way star clusters at very different dynamics evolutionary stages
Andrés E. Piatti, Mateus S. Angelo, Wilton S. Dias
We report astrophysical properties of 12 Milky Way open clusters located beyond the circle around the Sun where the number of catalogued open clusters is thought to be statisticall…
The VISCACHA survey - I. Overview and First Results
Francisco F. S. Maia, Bruno Dias, João F. C. Santos +15
The VISCACHA (VIsible Soar photometry of star Clusters in tApii and Coxi HuguA) Survey is an ongoing project based on deep photometric observations of Magellanic Cloud star cluster…
