ALMA's sharpest view of IRAS 08544-4431: Unveiling the dust distribution asymmetries in the circumbinary disk
Maksym Mohorian, Devika Kamath, Elizabeth Cappellazzo +10
The interactions between post-asymptotic giant branch (post-AGB) binaries and their circumbinary disks play a central role in shaping the evolution of these systems. Circumbinary d…
The Last Gasps of a Dying Star: ALMA Observations of the Pre-Planetary Nebula IRAS 06530-0213
Raghvendra Sahai, Wouter Vlemmings, Guillermo Quintana-Lacaci +16
We present high angular-resolution () ALMA observations of millimeter-wave line and continuum emission (at and mm) in the pre-planetary ne…
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…
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. Fonfría, 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…
