Ionized gas emission in protoplanetary disks with the SKAO
Greta Guidi, Christian Rab, Barbara Ercolano +20
Protoplanetary disks represent a crucial stage in the evolution of Young Stellar Objects towards the formation of fully formed planetary systems. While substantial progress has bee…
Unveiling Complex Chemistry in Planet-forming Disks with the SKAO
Linda Podio, Lisa Giani, Catherine Walsh +38
The chemical composition of planets is inherited from that of the natal protoplanetary disk at the time of planet formation. In recent years, we have made huge progress in characte…
Chemical Complexity in the Early Stages of Star Formation in the SKAO Era
Eleonora Bianchi, Mathilde Bouvier, Claudio Codella +44
About 350 molecules have been identified in the interstellar medium (ISM), including complex molecules relevant to prebiotic chemistry. A remarkable level of molecular diversity ha…
Characterising the multiple protostellar system VLA 1623-2417 with JWST, ALMA and VLA: outflow origins, dust growth and an unsettled disk
Isaac C. Radley, Gemma Busquet, John D. Ilee +16
Utilising JWST, ALMA and the VLA we present high angular resolution (0.06''- 0.42''), multi-wavelength (4 micron - 3cm) observations of the VLA 1623-2417 protostellar system to cha…
Molecules with ALMA at Planet-forming Scales (MAPS) XIII: HCO and disk ionization structure
Yuri Aikawa, Gianni Cataldi, Yoshihide Yamato +25
We observed HCO and HCO emission towards the five protoplanetary disks around IM Lup, GM Aur, AS 209, HD 163296, and MWC 480 as part of the MAPS proj…
Molecules with ALMA at Planet-forming Scales (MAPS) XI: CN and HCN as Tracers of Photochemistry in Disks
Jennifer B. Bergner, Karin I. Oberg, Viviana V. Guzman +23
UV photochemistry in the surface layers of protoplanetary disks dramatically alters their composition relative to previous stages of star formation. The abundance ratio CN/HCN has…
