Context. The globular cluster AL 3 is old and located in the inner bulge. Three individual stars were observed with the Phoenix spectrograph at the Gemini South telescope. The wavelength region contains prominent lines of CN, OH, and CO, allowing the derivation of C, N, and O abundances of cool stars. Aims. We aim to derive C, N, O abundances of three stars in the bulge globular cluster AL 3, and additionally in stars of NGC 6558 and HP 1. The spectra of AL 3 allows us to derive the cluster’s radial velocity. Methods. For AL 3, we applied a new code to analyse its colour-magnitude diagram. Synthetic spectra were computed and compared to observed spectra for the three clusters. Results. We present a detailed identification of lines in the spectral region centred at 15 555 Å, covering the wavelength range 15 525–15 590 Å. C, N, and O abundances are tentatively derived for the sample stars.

“…This cluster was analysed in terms of Colour-Magnitude Diagrams (CMD) byRich et al (1998) Rossi et al (2015). obtained a proper-motion-cleaned CMD, and presented a proper motion analysis, from which a study of its orbits was given in Pérez-Villegas et al(2018, 2020).The globular cluster Cl Haute-Provence 1 or HP 1, also designated BH 229 and ESO 455-SC11, was discovered byDufay et al (1954).

Os principais objetivos deste trabalho são a melhor compreensão da formação e evolução do bojo Galáctico, e da nucleossíntese ocorrida nas primeiras supernovas que enriqueceram o bojo em elementos químicos.O bojo galáctico está sob intensa discussão quanto a sua origem e populações estelares.Este contém estrelas muito antigas pobres em metais que estão espacialmente distribuidas em uma forma esferoidal que se formaram durante o processo inicial de formação de bojo.O bojo tem uma barra que se formou provavelmente a partir do disco espesso. Esta componente contém principalmente estrelas ricas em metais.O principal objetivo deste trabalho é expandir os estudos de abundâncias químicas em diferentes pupulações estelares do bojo Galáctico, associado com o estudo de processos de nucleossíntese. As características de abundâncias químicas de diferentes grupos de elementos como elementos-α, elementos do pico do ferro e elementos pesados, vem sendo considerado como discriminadores chave de populações estelares e processos de nucleossíntese. Este trabalho também visa relacionar as perspectivas dos futuros instrumentos VLT-MOONS, VLT-CUBES e ELT-MOSAIC no estudo dessas populações estelares.
