Searching for Corannulene with ALMA: Observations of the Red Rectangle Nebula
Elise Koo, Alessandra Candian, Michiel Hogerheijde +6
Polycyclic Aromatic Hydrocarbons (PAHs) are organic molecules responsible for the Aromatic Infrared Bands (AIBs), observed across a multitude of astrophysical environments. Despite…
3He: Does the problem persists?
L. Guzman-Ramirez, J. E. Pineda, A. A. Zijlstra +2
To understand the chemical evolution of the Galaxy, we need to understand the contribution of PNe in the 3He abundance. 3He abundances have been detected only in a couple of PNe, t…
A distance estimate based on angular expansion for the planetary nebula NGC 6881
Lizette Guzman-Ramirez, Yolanda Gomez, Laurent Loinard +1
In this paper, we report on high angular resolution radio observations of the planetary nebula NGC 6881 obtained with the Very Large Array at a wavelength of 6 cm. The emission app…
Carbon chemistry in Galactic Bulge Planetary Nebulae
L. Guzman-Ramirez, A. A. Zijlstra, R. Ni Chuimin +4
Galactic Bulge Planetary Nebulae show evidence of mixed chemistry with emission from both silicate dust and PAHs. This mixed chemistry is unlikely to be related to carbon dredge up…
