Detection of unidentified molecular pure rotational lines in C-rich PNe I. The fullerene-containing PN IC 418
T. Huertas-Roldán, J. P. FonfrÃa, 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…
VLTI/PIONIER imaging of post-AGB binaries. An INSPIRING hunt for inner rim substructures in circumbinary discs
Toon De Prins, Akke Corporaal, Jacques Kluska +10
We image the detailed inner rim morphology for a sample of post-AGB circumbinary discs observed using NIR interferometry. At resolutions down to ~1-2 mas (corresponding to ~1-10 AU…
M1-92: AGB interruption and isotopic ratio paradox. Chemistry and morpho-kinematics from improved shapemol modelling
E. Masa, J. Alcolea, M. Santander-GarcÃa +5
The shaping of planetary nebulae on their evolution from asymptotic giant branch circumstellar envelopes to their final, most often axisymmetrical, form is still a process with man…
CO observations in rotating circumbinary post-AGB disks
I. Gallardo Cava, J. Alcolea, H. Van Winckel +3
There is a group of post-AGB stars that are part of a binary system and that show a significant NIR excess. These systems are known to host disks with Keplerian or quasi-Keplerian…
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…
Deep survey of millimeter RRLs towards the planetary nebulae IC 418 and NGC 7027
Teresa Huertas-Roldán, Javier Alcolea, D. AnÃbal GarcÃa-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…
