The H line emission of the Be star Psc: the last 40 years
Ronaldo S. Levenhagen, Marcos P. Diaz, Eduardo B. Amôres +1
A study on the photosphere and disc of the Be star Psc is presented. We recover almost 40 years of high-resolution spectroscopic observations and additional data gathered from…
Chemical abundances of Seyfert 2 AGNs I. Comparing oxygen abundances from distinct methods using SDSS
O. L. Dors, P. Freitas-Lemes, E. B. Amores +6
We compare the oxygen abundance (O/H) of the Narrow Line Regions (NLRs) of Seyfert 2 AGNs obtained through strong-line methods and from direct measurements of the electron temperat…
The long bar as seen by the VVV survey: I. Colour-magnitude diagrams
C. González-Fernández, M. López-Corredoira, E. B. Amôres +3
The VISTA Variable Survey (VVV) is able to map the Galaxy at l<0 with an unpaired depth (at least 3 mag deeper than 2MASS), opening new possibilities for studying the inner structu…
