Atomium: The astounding complexity of the near circumstellar environment of the M-type AGB star R Hydrae. I. Morpho-kinematical interpretation of CO and SiO emission
Ward Homan, Bannawit Pimpanuwat, Fabrice Herpin +36
Evolved low- to intermediate-mass stars are known to shed their gaseous envelope into a large, dusty, molecule-rich circumstellar nebula which typically develops a high degree of s…
Atomium: A high-resolution view on the highly asymmetric wind of the AGB star Pi1 Gruis. I. First detection of a new companion and its effect on the inner wind
Ward Homan, Miguel Montarges, Bannawit Pimpanuwat +35
The nebular circumstellar environments of cool evolved stars are known to harbour a rich morphological complexity of gaseous structures on different length scales. A large part of…
Radio observations of planetary nebulae: no evidence for strong radial density gradients
Marcin Hajduk, Peter A. M. van Hoof, Karolina Śniadkowska +4
Radio continuum observations trace thermal emission of ionized plasma in planetary nebulae and bring useful information on nebular geometries. A model of homogeneous sphere or shel…
Herschel Planetary Nebula Survey (HerPlaNS): Hydrogen Recombination Laser Lines in Mz 3
Isabel Aleman, Katrina Exter, Toshiya Ueta +12
The bipolar nebula Menzel 3 (Mz 3) was observed as part of the \textit{Herschel} Planetary Nebula Survey (\textit{HerPlaNS}), which used the PACS and SPIRE instruments aboard the \…
Opening PANDORA's box: APEX observations of CO in PNe
L. Guzman-Ramirez, A. I. Gomez-Ruiz, H. M. J. Boffin +5
Context. Observations of molecular gas have played a key role in developing the current understanding of the late stages of stellar evolution. Aims. The survey Planetary nebulae AN…
The extinction and dust-to-gas structure of the planetary nebula NGC 7009 observed with MUSE
J. R. Walsh, A. Monreal-Ibero, M. J. Barlow +3
The large field and wavelength range of MUSE is well suited to mapping Galactic planetary nebulae (PN). The bright PN NGC 7009 was observed with MUSE on the VLT during the Science…
