The influence of bars in the star formation history and chemical evolution of disk galaxies
This is a pilot study part of a larger program devoted to understand the influence of bars in the evolution of galaxy disks. Some of the goals of this...
The influence of internal gravity waves on the light elements depletion among F-type stars
It is proposed that the Li abundances in F-type stars can be affected by the weak mixing generated by internal gravity waves since the absence of Li is so...
The influence of spot saturation on DIMM seeing measurements
The DIMM is a widely accepted and often used instrument for seeing measurements. Nevertheless, its incorrect use may give rise to errors in seeing values. A...
Galaxy mergers and interactions are mechanisms which should drive the formation of bars. Therefore, we could expect that the fraction of barred galaxies...
We present Keck K-band observations of GX 17+2 which reveal a bright counterpart in the radio error circle of Deutsch et al. (1999), coincident with their star...
The Infrared Nuclear Emission of Seyfert Galaxies on Parsec Scales: Testing the Clumpy Torus Models
We present subarcsecond resolution mid-infrared (mid-IR) photometry in the range from 8 to 20 μm of 18 nearby Seyfert galaxies, reporting high spatial...
