Milky Way's warped disc traced by AGB stars
Tanya Kushwahaa, Mikako Matsuura, Jason A. S. Hunt +3
While the presence of the Galactic warp has long been established from observations of \HI\, gas, the \textit{Gaia} measurements of over 1 billion stars with parallaxes have enable…
Detection of CO ice in the planetary nebula NGC 6302
Charmi Bhatt, Simon W. Cao, Jan Cami +20
Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…
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…
JWST/NIRCam imaging of the Bipolar Planetary Nebula NGC 6537: the (Infra)red Spider, Revealed
Joel Kastner, Paula Moraga Baez, Bruce Balick +5
We present James Webb Space Telescope (JWST) near-infrared (NIRCam) Br, H, [Fe II], and PAH imaging of the molecule-rich, high-excitation bipolar planetary nebula (PN) NGC…
The PRIMA promise of deciphering interstellar dust evolution with observations of the nearby Universe
Frédéric Galliano, Maarten Baes, Léo Belloir +25
This paper develops a few science cases, using the PRIMA far-IR probe, aimed at achieving several breakthroughs in our understanding of the dust properties and their evolution. We…
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…
