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…
Chemistry in the High expansion-velocity C-rich evolved star AFGL2233. Isotopic ratios, peculiarities and evolutionary status
G. Quintana-Lacaci, M. Agúndez, L. Velilla-Prieto +4
High expansion velocity carbon stars (HVCs) are a rare class of evolved stars whose circumstellar envelopes (CSEs) combine C-rich chemistry with unusually high expansion velocities…
Atmospheric molecular blobs shape up circumstellar envelopes of AGB stars
L. Velilla-Prieto, J. P. FonfrÃa, M. Agúndez +8
During their thermally pulsing phase, Asymptotic Giant Branch (AGB) stars eject material that forms extended dusty envelopes. Visible polarimetric imaging found clumpy dust clouds…
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…
High-Speed Outflows and Dusty Disks during the AGB to PN Transition: The PANORAMA survey
Raghvendra Sahai, Javier Alcolea, Bruce Balick +15
As mass-losing asymptotic giant branch (AGB) stars evolve to planetary nebulae (PNe), the mass outflow geometries transform from nearly spherical to extreme aspherical. The physica…
Continuum and molecular emission from the inner regions of the symbiotic system R Aquarii
M. Gómez-Garrido, V. Bujarrabal, J. Alcolea +3
Symbiotic systems often include an asymptotic giant branch (AGB) star and a hot compact companion, such as a white dwarf, that are in close interaction. Due to the intense ultravio…
