Detection of C Combination Bands in the Near-IR Spectrum of Tc 1
Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26
We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying th…
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…
The Nearby Evolved Stars Survey III: First data release of JCMT CO-line observations
S. H. J. Wallström, P. Scicluna, S. Srinivasan +37
Low- to intermediate-mass (0.88 M) evolved stars contribute significantly to the chemical enrichment of the interstellar medium in the local Universe, making accur…
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…
