Detection of unidentified molecular pure rotational lines in C-rich PNe I. The fullerene-containing PN IC 418
T. Huertas-Roldán, J. P. Fonfría, J. Alcolea +7
Molecular emission is observed in a wide variety of astrophysical environments, yet a substantial fraction of spectral features detected at mm wavelengths remains unidentified. Ide…
CH3CCH as a thermometer in warm molecular gas
Yuqiang Li, Junzhi Wang, Juan Li +9
Kinetic temperature is a fundamental parameter in molecular clouds. Symmetric top molecules, such as NH and CHCCH, are often used as thermometers. However, at high temperat…
Deep survey of millimeter RRLs towards the planetary nebulae IC 418 and NGC 7027
Teresa Huertas-Roldán, Javier Alcolea, D. Aníbal García-Hernández +7
The circumstellar environments of PNe are wonderful chemically rich astrophysical laboratories in which the ionization of atoms and the formation of simple and complex molecules ca…
Circumstellar envelopes of semi-regular long-period variables: mass-loss rate estimates and general model-fitting of the molecular gas
J. J. Díaz-Luis, J. Alcolea, V. Bujarrabal +4
We aim to study the main properties of a volume-limited unbiased sample of well-characterized semi-regular variables (SRs) in order to clarify important issues, such as the formati…
Study of fullerene-based molecular nanostructures in planetary nebulae
J. J. Díaz-Luis
The main goal of this thesis is to unveil some questions related to the formation of complex fullerene-based molecules in space, with the aim of resolving some key problems in astr…
GTC/CanariCam mid-IR imaging of the fullerene-rich Planetary Nebula IC 418: searching for the spatial distribution of fullerene-like molecules
J. J. Díaz-Luis, D. A. García-Hernández, A. Manchado +3
We present seeing-limited narrow-band mid-IR GTC/CanariCam images of the spatially extended fullerene-containing planetary nebula (PN) IC 418. The narrow-band images cover the C60…
A search for hydrogenated fullerenes in fullerene-containing planetary nebulae
J. J. Díaz-Luis, D. A. García-Hernández, A. Manchado +1
Detections of C60 and C70 fullerenes in planetary nebulae (PNe) of the Magellanic Clouds and of our own Galaxy have raised the idea that other forms of carbon such as hydrogenated…
