CO rotational line emission in very red carbon stars in the Magellanic Clouds
M. A. T. Groenewegen, A. Nanni, M. L. Boyer +11
Stars of low and intermediate initial mass lose most of their stellar mass at the end of their lives during the asymptotic giant branch (AGB) phase. Determining their gas and dust…
Detection of CH3+ in the O-rich planetary nebula NGC 6302
Charmi Bhatt, Jan Cami, Els Peeters +33
Planetary nebulae are sites where ejected stellar material evolves into complex molecules, but the precise physical conditions and chemical routes that govern these processes are u…
The JWST/MIRI view of the planetary nebula NGC 6302 I.: a UV irradiated torus and a hot bubble triggering PAH formation
Mikako Matsuura, Kevin Volk, Patrick Kavanagh +34
NGC 6302 is a spectacular bipolar planetary nebula (PN) whose spectrum exhibits fast outflows and highly ionized emission lines, indicating the presence of a very hot central star…
JWST observations of the Ring Nebula (NGC 6720) -- II. PAH emission
Nicholas Clark, Els Peeters, Nick L. J. Cox +16
Polycyclic aromatic hydrocarbons (PAHs) and carbonaceous dust have been observed in clumpy circumstellar environments, yet their formation and evolutionary pathways in such environ…
JWST observations of the Ring Nebula (NGC 6720): I. Imaging of the rings, globules, and arcs
R. Wesson, Mikako Matsuura, Albert A. Zijlstra +18
We present JWST images of the well-known planetary nebula NGC 6720 (the Ring Nebula), covering wavelengths from 1.6m to 25 m. The bright shell is strongly fragmented with som…
On the detection of CO and mass loss of Bulge OH/IR stars
Joris Blommaert, Martin Groenewegen, Kay Justtanont +1
We report on the succesful search for CO (2-1) and (3-2) emission associated with OH/IR stars in the Galactic Bulge. We observed a sample of eight extremely red AGB stars with the…
