Colour-Magnitude Diagrams of candidate age-gap filling LMC clusters
Eduardo Balbinot, Basilio Santiago, Leandro Kerber +2
The LMC has a rich star cluster system spanning a wide range of ages and masses. One striking feature of the LMC cluster system is the existence of an age gap between 3-10 Gyrs. Fo…
Isospin effects and the density dependence of the nuclear symmetry energy
S. R. Souza, M. B. Tsang, B. V. Carlson +3
The density dependence of the nuclear symmetry energy is inspected using the Statistical Multifragmentation Model with Skyrme effective interactions. The model consistently conside…
Probing the near infrared stellar population of Seyfert galaxies
R. Riffel, M. G. Pastoriza, A. Rodriguez-Ardila +1
We employ IRTF SpeX NIR (0.8-2.4 microns) spectra to investigate the stellar population (SP), active galactic nuclei (AGN) featureless continuum (FC) and hot dust properties in 9 S…
On the nature of the near-UV extended light in Seyfert galaxies
V. M. Muñoz Marín, T. Storchi-Bergmann, R. M. González Delgado +4
We study the nature of the extended near-UV emission in the inner kiloparsec of a sample of 15 Seyfert galaxies which have both near-UV (F330W) and narrow band [OIII] high resoluti…
On the possible existence of short-period g-mode instabilities powered by nuclear burning shells in post-AGB H-deficient (PG1159-type) stars
A. H. Córsico, L. G. Althaus, M. M. Miller Bertolami +2
We present a pulsational stability analysis of hot post-AGB H-deficient pre-white dwarf stars with active He-burning shells. The stellar models employed are state-of-the-art equili…
Noncommutative quantum mechanics as a gauge theory
F. S. Bemfica, H. O. Girotti
The classical counterpart of noncommutative quantum mechanics is a constrained system containing only second class constraints. The embedding procedure formulated by Batalin, Fradk…
