Detection of CH, CH and H molecules in the Young Planetary Nebula IC 4997
N. Kameswara Rao, David L. Lambert, Arumalla B. S. Reddy +3
We have detected CH and CH molecular absorption lines from the young compact planetary nebula IC 4997 from high resolution optical spectra. A high-resolution infra-red (H and…
On the circumstellar envelopes of semi-regular long-period variables
J. J. Díaz-Luis, J. Alcolea, V. Bujarrabal +3
The mass loss process along the AGB phase is crucial for the formation of circumstellar envelopes (CSEs), which in the post-AGB phase will evolve into planetary nebulae (PNe). Ther…
A search for diffuse bands in fullerene planetary nebulae: evidence of diffuse circumstellar bands
J. J. Diaz-Luis, D. A. Garcia-Hernandez, N. Kameswara Rao +2
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)…
Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection
D. A. Garcia-Hernandez, J. J. Diaz-Luis
We present high-resolution (R~15000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already been found. These spectra…
