CN and CH bands in Exoplanet Host Stars
(Asociación Argentina de Astronomía, 2012-02)
En este trabajo medimos la intensidad de las bandas moleculares CN y CH en una muestra de estrellas con y sin exoplanetas (indices δS3839, δS4142 y δCH4300). El índice δS3839 parece ser menor en estrellas sin exoplanetas. ...
G331.512-0.103: An Interstellar Laboratory for Molecular Synthesis. I. the Ortho-to-para Ratios for CH3OH and CH3CN
(IOP Publishing, 2018-02)
Spectral line surveys reveal rich molecular reservoirs in G331.512-0.103, a compact radio source in the center of an energetic molecular outflow. In this first work, we analyse the physical conditions of the source by means ...
Galactic or extragalactic chemical tagging for NGC3201? Discovery of an anomalous CN-CH relation
(EDP SCIENCES S A, 2018)
Context. The origin of the globular cluster (GC) NGC 3201 is under debate. Its retrograde orbit points to an extragalactic origin, but no further chemical evidence supports this idea. Light-element chemical abundances are ...
Galactic or extragalactic chemical tagging for NGC 3201?: Discovery of an anomalous CN-CH relation
(EDP Sciences, 2018-06)
The origin of the globular cluster (GC) NGC 3201 is under debate. Its retrograde orbit points to an extragalactic origin, but no further chemical evidence supports this idea. Light-element chemical abundances are useful ...
Estudio magnético de sistemas polimetálicos de metales de la primera serie de transición
(2013)
En este trabajo de tesis se abordó la síntesis, caracterización estructural y el estudio magnético de nuevos y novedosos sistemas polinucleares de cero dimensionalidad. Estos complejos polinucleares fueron obtenidos por ...
Catalytic disproportionation of N-alkylhydroxylamines bound to pentacyanoferrates
(Royal Society of Chemistry, 2009-02)
The substituted hydroxylamines, CH3N(H)OH (N-methylhydroxylamine) and (CH3)2NOH (N,N-dimethylhydroxylamine), disproportionate catalytically to the corresponding alkylamines and oxidation products, only in the presence of ...
