Self-consistent physical parameters for MC clusters from CMD modelling: application to SMC clusters observed with the SOAR telescope
Bruno M. S. Dias, Leandro O. Kerber, Basílio X. Santiago +2
The Magellanic Clouds (MCs) present a rich system of stellar clusters that can be used to probe the dynamical and chemical evolution of these neighboring and interacting irregular…
Metallicity effects on the modified wind momentum of CSPN
W. J. Maciel, G. R. Keller, R. D. D. Costa
Recent investigations on the central stars of planetary nebulae (CSPN) indicate that the masses based on model atmospheres can be much larger than the masses derived from theoretic…
HI aperture synthesis and optical observations of the pair of galaxies NGC 6907 and 6908
S. Scarano, Felipe R. H. Madsen, Nirupam Roy +1
NGC 6908, a S0 galaxy situated in direction of NGC 6907, was only recently recognized as a distinct galaxy, instead of only a part of NGC 6907. We present 21 cm radio synthesis obs…
Chemical Potential and the Nature of the Dark Energy: The case of phantom
J. A. S. Lima, S. H. Pereira
The influence of a possible non zero chemical potential on the nature of dark energy is investigated by assuming that the dark energy is a relativistic perfect simple fluid obe…
Searching for Star Formation Outside Galaxies: Multiwavelength Analysis of the Intragroup Medium of HCG100
Duilia F. de Mello, Sergio Torres-Flores, Claudia L. Mendes de Oliveira
We used multiwavelength data (HI, FUV, NUV, R) to search for evidence of star formation in the intragroup medium of the Hickson Compact Group 100. We find that young star-forming r…
Dynamical Mutation of Dark Energy
L. R. Abramo, R. C. Batista, L. Liberato +1
We discuss the intriguing possibility that dark energy may change its equation of state in situations where large dark energy fluctuations are present. We show indications of this…
