Abundances in the Galactic bulge: results from planetary nebulae and giant stars
(EDP SCIENCES S A, 2009)
Context. Our understanding of the chemical evolution (CE) of the Galactic bulge requires the determination of abundances in large samples of giant stars and planetary nebulae (PNe). Studies based on high resolution ...
Seasonal and interannual variability in population abundances of the intertidal macroinfauna of Queule river estuary, south-central Chile
(Sociedad de Biología de Chile, 2001)
Effect of body size on the abundance of ectoparasitic mites on the wild rodent Oligoryzomys nigripes
(Walter De Gruyter Gmbh, 2015-09-01)
The abundance of parasites on a host can be affected by several factors; in this study, we investigated the influence of sex and body size of the host rodent Oligoryzomys nigripes on the abundance of ectoparasitic mites ...
Abundance variations in the globular cluster M71 (NGC 6838)
(EDP SCIENCES S A, 2008)
Context. Abundance variations in moderately metal-rich globular clusters can give clues about the formation and chemical enrichment of globular clusters. Aims. CN, CH, Na, Mg and Al indices in spectra of 89 stars of the ...
Masses, oxygen, and carbon abundances in CHEPS dwarf stars
(EDP Sciences, 2019)
Context. We report the results from the determination of stellar masses, carbon, and oxygen abundances in the atmospheres of 107 stars from the Calan-Hertfordshire Extrasolar Planet Search (CHEPS) programme. Our stars are ...
PLANETARY NEBULAE IN THE INNER MILKY WAY: NEW ABUNDANCES
(UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA, 2010)
The study of planetary nebulae in the inner-disk and bulge gives important information on the chemical abundances of elements such as He, N, O, Ar, Ne, and on the evolution of these abundances, which is associated with the ...
