Hydrogen depleted environments are considered an essential requirement for the formation of fullerenes. The recent detection of C60 and C70 fullerenes in what was interpreted as the hydrogen-poor inner region of a post-final helium shell flash planetary nebula (PN) seemed to confirm this picture. Here, we present strong evidence that challenges the current paradigm regarding fullerene formation, showing that it can take place in circumstellar environments containing hydrogen. We report the… Expand

Fullerenes have recently been identified in space and they may play a significant role in the gas and dust budget of various astrophysical objects including planetary nebulae (PNe), reflectionExpand
Fullerenes and fulleranes in circumstellar envelopes
Three decades of search have recently led to convincing discoveries of cosmic fullerenes. The presence of C60 and C+ 60 in both circumstellar and interstellar environments suggests that theseExpand

We present 10 new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule. These new fullerene detections togetherExpand
Top-down formation of fullerenes in the interstellar medium.
TLDR
This model predicts absolute abundances of C60 are up to several 10-4 of the elemental carbon, which is consistent with observational studies, and according to this model, once formed, C60 can survive much longer than other fullerenes in highly irradiated environments. Expand
A Catalog of Diffuse Interstellar Bands in Fullerene-Containing Planetary Nebulae
Abstract Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common fullerenes (C60 and C70) aroundExpand
The Formation of Fullerenes in Planetary Nebulae
In the last decade, fullerenes have been detected in a variety of astrophysical environments, with the majority being found in planetary nebulae. Laboratory experiments have provided us with insightsExpand
Fullerenes and Proto-fullerenes in Interstellar Carbon Dust
Laboratory spectra of hydrogenated amorphous carbon (HAC) particles prepared under a variety of conditions show spectral features at 7.05, 8.5, 17.4, and 18.9 μm (1418, 1176, 575, and 529 cm–1) thatExpand
Metallofullerene and fullerene formation from condensing carbon gas under conditions of stellar outflows and implication to stardust
TLDR
It is demonstrated that Na effectively nucleates formation of Na@C60 and other metallofullerenes during carbon condensation under highly energetic conditions in oxygen- and hydrogen-rich carbon gas, which should be directly applicable to gas-phase chemistry involving stellar environments, such as supernova ejecta.

Detection of C60 and C70 in a Young Planetary Nebula
TLDR
The environment of Tc 1, a peculiar planetary nebula whose infrared spectrum shows emission from cold and neutral C60 and C70, is studied, indicating that if the conditions are right, fullerenes can and do form efficiently in space. Expand
A search for C60 in carbonaceous chondrites.
TLDR
Analysis of interior samples of the Murchison meteorite by two routes yielded an upper limit of 2 ppb for its C60 content, as compared to parts per million levels for individual polycyclic aromatic hydrocarbons (PAHs), arguing against the ubiquitous presence of C60 in the interstellar medium.
