Hunting white dwarfs at the center of planetary nebulae
Javier Ahumada, Walter Weidmann, Marcelo Miller Bertolami +1
We present Gemini-South observations of nine faint and extended planetary nebulae. Using direct images taken with the spectrograph GMOS, we built the vs. di…
Breaking the dichotomy between typical and anomalous globular clusters: the case of NGC 3201
Bruno Dias, Ignacio Araya, João Paulo Nogueira-Cavalcante +2
We recently discovered that NGC 3201 has characteristics that set it outside the current twofold classification scheme for Galactic globular clusters (GCs). Most GCs are mono-metal…

Bruno Dias, Ignacio Araya, João Paulo Nogueira-Cavalcante +2
(ABRIDGED) The origin of the globular cluster (GC) NGC3201 is under debate. Its retrograde orbit points to an extragalactic origin, but no further chemical evidence supports this i…
