Discovery of two cyano derivatives of acenaphthylene (C $_{12}$ H $_{8}$ ) in TMC-1 with the QUIJOTE line survey

J. Cernicharo, C. Cabezas, R. Fuentetaja +12

We report the discovery in TMC-1 of two cyano derivatives of the PAH acenaphthylene (C $_{12}$ H $_{8}$ ). We have found two series of lines with the QUIJOTE line survey that we assign t…

The rich interstellar reservoir of dinitriles: Detection of malononitrile and maleonitrile in TMC-1

M. Agundez, C. Bermudez, C. Cabezas +7

While the nitrile group is by far the most prevalent one among interstellar molecules, the existence of interstellar dinitriles (molecules containing two -CN groups) has recently b…

More sulphur in TMC-1: Discovery of the NC $_{3}$ S and HC $_{3}$ S radicals with the QUIJOTE line survey

J. Cernicharo, C. Cabezas, M. Agúndez +4

We present the detection of the free radicals NC $_{3}$ S and HC $_{3}$ S towards TMC-1 with the QUIJOTE line survey. The derived column densities are (1.4 $\pm$ 0.2) $\times$ 10 $^{11}$ for NC…

Discovery of the interstellar cyanoacetylene radical cation HC $_{3}$ N $^{+}$

C. Cabezas, M. Agúndez, Y. Endo +4

We report the first identification in space of HC $_{3}$ N $^{+}$ , the simplest member of the family of cyanopolyyne cations. Three rotational transitions with half-integer quantum number…

QUIJOTE discovery of the cation radicals HC5N+ and HC7N+

J. Cernicharo, C. Cabezas, M. Agúndez +4

We present the discovery with the QUIJOTE line survey of the cations HC5N+ and HC7N+ in the direction of TMC-1. Seven lines with half-integer quantum numbers from J=25/2-23/2 to 37…

CN and CCH derivatives of ethylene and ethane: Confirmation of the detection of CH $_{3}$ CH $_{2}$ CCH in TMC-1

J. Cernicharo, B. Tercero, M. Agúndez +4

We present a study of CH $_{3}$ CH $_{2}$ CCH, CH $_{3}$ CH $_{2}$ CN, CH $_{2}$ CHCCH, and CH $_{2}$ CHCN in TMC-1 using the QUIJOTE $^{1}$ line survey. We confirm the presence of CH $_{3}$ CH $_{2}$ CCH in TMC-1,…

Doubly substituted isotopologues of HCCCN in TMC-1: Detection of D13CCCN, DC13CCN, DCC13CN, DCCC15N, H13C13CCN, H13CC13CN, HC13C13CN, HCC13C15N, and HC13CC15N

B. Tercero, N. Marcelino, E. Roueff +5

We report the first detection in space of a complete sample of nine doubly substituted isotopologues of HCCCN towards the cyanopolyyne peak of TMC-1 using observations of the QUIJO…
