M1-92: AGB interruption and isotopic ratio paradox. Chemistry and morpho-kinematics from improved shapemol modelling
E. Masa, J. Alcolea, M. Santander-García +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…
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…
Uncovering the structure and kinematics of the ionized core of M\,2-9 with ALMA
C. Sánchez Contreras, D. Tafoya, J. P. Fonfria +3
We present interferometric observations at 1 and 3\,mm with the Atacama Large Millimeter Array (ALMA) of the free-free continuum and mm-wavelength recombination line (mRRL) emissio…
Morpho-kinematical modelling in the molecular zoo beyond CO: the case of M 1-92
M. Santander-García, E. Masa, J. Alcolea +1
Ongoing improvements of sub-mm- and mm-range interferometers and single-dish radiotelescopes are progressively allowing the detailed study of planetary nebulae (PNe) in molecular s…
Mapping NGC 7027 in New Light: CO and HCO Emission Reveal Its Photon- and X-ray-Dominated Regions
Jesse Bublitz, Joel H. Kastner, Pierre Hily-Blant +7
The young and well-studied planetary nebula NGC 7027 harbors significant molecular gas that is irradiated by luminous, point-like UV (central star) and diffuse (shocked nebular) X-…
Dissecting the central regions of OH 231.8 + 4.2 with ALMA: a salty rotating disk at the base of a young bipolar outflow
C. Sánchez Contreras, J. Alcolea, R. Rodríguez Cardoso +5
We present ALMA continuum and molecular line emission maps at 1 mm of OH 231.8, a well studied bipolar nebula around an AGB star. The excellent angular resolution of our maps…
