The JWST Proto-PAH Project: Detection of the methyl radical CH in the highly evolved C-rich object SMP LMC 011
Jialu Li, D. A. García-Hernández, A. Manchado +17
We report the first detection of the neutral methyl radical CH in a highly evolved C-rich object, SMP LMC 011, using JWST MIRI/MRS. CH is well fitted by an excitation tempe…
Late-Time Evolution of the Massive Stellar Merger M101 OT2015-1
Marco A. Gómez-Muñoz, Nadejda Blagorodnova, Tomasz Kamiński +6
Luminous red novae (LRNe) are astronomical transients arising from unstable mass transfer and common envelope phases in close binary systems, culminating in stellar mergers. Their…
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…
Hot springs and dust reservoirs: JWST reveals the dusty, molecular aftermath of extragalactic stellar mergers
Viraj Karambelkar, Mansi Kasliwal, Ryan M. Lau +7
We present James Webb Space Telescope (JWST) observations of four Luminous Red Novae (LRNe): dusty, extragalactic transients from stellar mergers following common-envelope evolutio…
An attempt to determine the magnetic field configuration in the planetary nebula K 3-35 with ALMA
L. Sabin, Q. Zhang, L. F. Miranda +1
We examined dust polarisation within the planetary nebula (PN) K 3-35 using the Atacama Large Millimeter/Submillimeter Array (ALMA). This investigation aimed to identify and trace…
Hydrogenated amorphous carbon grains as an alternative carrier of the 913m plateau feature in the fullerene planetary nebula Tc 1
M. A. Gómez-Muñoz, D. A. García-Hernández, R. Barzaga +2
Fullerenes have been observed in several astronomical objects since the discovery of C in the mid-infrared (mid-IR) spectrum of the planetary nebula (PN) Tc 1. It has been s…
An ultraviolet spectral study of fullerene-rich planetary nebulae
M. A. Gómez-Muñoz, D. A. García-Hernández, A. Manchado +2
Several planetary nebulae (PNe) have been found to contain both polycyclic aromatic hydrocarbon (PAH-like) species and fullerenes (C) distinguished by their mid-infrared emi…
Infrared spectral fingerprint of neutral and charged endo- and exohedral metallofullerenes
R. Barzaga, D. A. Garcia-Hernandez, S. Diaz-Tendero +5
Small metal-containing molecules have been detected and recognized as one of the hybrid species efficiently formed in space; especially in the circumstellar envelopes of evolved st…
The origin of the planetary nebula M 1-16. A morphokinematic and chemical analysis
M. A. Gómez-Muñoz, R. Vázquez, L. Sabin +4
We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a detailed morpho-kinemati…
Catalog of Planetary Nebulae detected by GALEX and corollary optical surveys
M. A. Gómez-Muñoz, L. Bianchi, A. Manchado
Planetary nebulae (PNe) consist of an ionized envelope surrounding a hot central star (CSPN) that emits mostly at ultraviolet (UV) wavelengths. Ultraviolet observations, therefore,…
Wide binaries in Planetary Nebulae with Gaia DR2
I. González-Santamaría, M. Manteiga, A. Manchado +3
Gaia Data Release 2 (DR2) was used to select a sample of 211 central stars of planetary nebulae (CSPNe) with good quality astrometric measurements, that we refer to as GAPN, Golden…
Morpho-kinematics of the planetary nebula NGC 3242: an analysis beyond its multiple-shell structure
M. A. Gómez-Muñoz, M. W. Blanco Cárdenas, R. Vázquez +3
In this paper we present the results of optical high-resolution imaging and spectroscopy of the complex planetary nebula (PN) NGC~3242. Our study is based on the analysis of the na…
