Stellar atmospheric parameters and chemical abundances of about 5 million stars from S-PLUS multi-band photometry
C. E. Ferreira Lopes, L. A. Gutiérrez-Soto, V. S. Ferreira Alberice +30
Context. Spectroscopic surveys like APOGEE, GALAH, and LAMOST have significantly advanced our understanding of the Milky Way by providing extensive stellar parameters and chemical…
[Fe II] 1.644m imaging survey of planetary nebulae with low-ionisation structures
Stavros Akras, Isabel Aleman, Denise R. Gonçalves +2
Low-ionisation structures (LISs) are commonly found in planetary nebulae (PNe) but they are still poorly understood. The recent discovery of unforeseen molecular hydrogen gas (H2)…
Detection of the [C I] 8727 emission line. Low-ionization structures in NGC 7009
Stavros Akras, Hektor Monteiro, Jeremy R. Walsh +5
We report the first spatially resolved detection of the near-infrared [C I] 8727 emission from the outer pair of low-ionization structures in the planetary nebula NGC 7009 from…
