Proyecto
Evolución Galáctica en el Grupo Local
La formación y evolución de galaxias es un problema fundamental en Astrofísica. Su estudio requiere “viajar atrás en el tiempo”, para lo cual hay dos enfoques...
Evolution of tidal disruption candidates discovered by XMM-Newton
Context: It has been demonstrated that active galactic nuclei are powered by gas accretion onto supermassive black holes located at their centres. The paradigm...
Evolutionary and pulsation properties of Type II Cepheids
We discuss the observed pulsation properties of Type II Cepheids (TIICs) in the Galaxy and in the Magellanic Clouds. We found that period (P) distributions...
Evolutionary stellar population synthesis with MILES - II. Scaled-solar and α-enhanced models
We present models that predict spectra of old- and intermediate-aged stellar populations at 2.51 Å (FWHM) with varying [α/Fe] abundance. The models are based on...
Evolved stars in the Local Group galaxies - II. AGB, RSG stars, and dust production in IC10
We study the evolved stellar population of the Local Group galaxy IC10, with the aim of characterizing the individual sources observed and to derive global...
Evolved stars in the Local Group galaxies - III. AGB and RSG stars in Sextans A
We study the evolved stellar population of the galaxy Sextans A. This galaxy is one of the lowest metallicity dwarfs in which variable asymptotic giant branch...
Exact Semianalytical Calculation of Rotation Curves with Bekenstein-Milgrom Nonrelativistic MOND
Astronomers derive MOdified Newtonian Dynamics (MOND) rotation curves using the simple algebraic rule of calculating the acceleration as equal to the Newtonian...
Excitation mechanisms of C II optical permitted lines in ionized nebulae
Context. Carbon is the fourth most abundant element in the universe and its distribution is critical to understanding stellar evolution and nucleosynthesis. In...
Excitation of emission lines by fluorescence and recombination in IC 418
We compare calculated intensities of lines of C II, N I, N II, O I and O II with a published deep spectroscopic survey of IC 418. Our calculations use a self...
