We present the new stellar population synthesis models based on the empirical stellar spectral library MILES, which can be regarded nowadays as standard in the...
Multiple Populations in Low-mass Globular Clusters: Palomar 13
Since the discovery of chemically peculiar stars in globular clusters in the last century, the study of multiple populations has become increasingly important...
Multiple stellar populations in globular clusters: Properties, origin, unsolved questions
Globular clusters (GCs) are fascinating objects nearly as old as the Universe that provide insight on a large variety of astrophysical and cosmological...
Massive stars are often found to be in pairs. This configuration is both a blessing and a curse. From it, we can estimate their exact properties such as their...
A grid of evolutionary synthesis models for different scenarios (initial mass function slope, metallicity, age, etc.) and computing a set of observables in a...
Near infrared survey of IRAS sources with colours like planetary nebulae. II
Near-IR standard photometry (J, H, K, L and M bands) of 38 IRAS sources with FIR colors similar to those of known planetary nebulae is presented. They are...
Near-infrared mapping of spiral galaxies. I - The SB galaxy NGC 2841 - Annular structure in the young disc component
NGC 2841 has been mapped in the J and K near-infrared bands out to some 10 kpc from its center. Maps and radial profiles in micron(J), micron(K) and J-K are...
New windows to the universe; Proceedings of the Eleventh European Regional Astronomy Meeting, Universidad de La Laguna, Spain, July 3-8, 1989. Part 1
Papers are presented on stellar structure and evolution. Particular attention is given to the deep CCD photometry of stars in the globular cluster M3; dynamical...
Nitrogen spectroscopy of O-type stars -- On the difficulties to derive reliable abundances
After a brief outline on the impact of massive stars for the cosmic and galactic evolution, we highlight the role of Nitrogen as a key element to test current...
