Spatial distribution of organics in the Horsehead nebula: Signposts of chemistry driven by atomic carbon
Claudio Hernández-Vera, Viviana V. Guzmán, Jérôme Pety +10
(Abridged) Complex organic molecules (COMs) are considered essential precursors to prebiotic species. While COMs were once expected to be efficiently destroyed under UV-irradiated…

High-angular-resolution ALMA imaging of the inhomogeneous dynamical atmosphere of the asymptotic giant branch star W Hya
K. Ohnaka, K. T. Wong, G. Weigelt +1
We present high-angular-resolution imaging of the asymptotic giant branch star W Hya with the Atacama Large Millimeter/submillimeter Array (ALMA) to probe the dynamics and chemistr…

Contemporaneous high-angular-resolution imaging of the AGB star W Hya in vibrationally excited H2O lines and visible polarized light with ALMA and VLT/SPHERE-ZIMPOL
K. Ohnaka, K. T. Wong, G. Weigelt +1
We present contemporaneous high-angular-resolution millimeter imaging and visible polarimetric imaging of the nearby asymptotic giant branch (AGB) star W Hya to better understand t…
