A search for Galactic post-asymptotic giant branch stars in Gaia DR3
Iker González-Santamaría, Minia Manteiga, Arturo Manchado +3
Context. When low and intermediate-mass stars leave the Asymptotic Giant Branch (AGB) phase, and before they reach the Planetary Nebulae stage, they enter a very brief and rather p…
Hydrogenated amorphous carbon grains as an alternative carrier of the 913m plateau feature in the fullerene planetary nebula Tc 1
M. A. Gómez-Muñoz, D. A. García-Hernández, R. Barzaga +2
Fullerenes have been observed in several astronomical objects since the discovery of C in the mid-infrared (mid-IR) spectrum of the planetary nebula (PN) Tc 1. It has been s…
An ultraviolet spectral study of fullerene-rich planetary nebulae
M. A. Gómez-Muñoz, D. A. García-Hernández, A. Manchado +2
Several planetary nebulae (PNe) have been found to contain both polycyclic aromatic hydrocarbon (PAH-like) species and fullerenes (C) distinguished by their mid-infrared emi…
