SMA Observations Reveal Abundant HNC Chemistry in Transition Disks
Kyle Gresko, Charles J. Law, Deryl E. Long +8
The physical and chemical conditions of protoplanetary disks shape the properties of nascent planetary systems. The line ratios and relative abundances of the HCN-HNC isomer pair a…
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…
AB Aur, a Rosetta stone for studies of planet formation (IV): C/O estimates from CS and SO interferometric observations
Pablo Rivière-Marichalar, Asunción Fuente, Romane le Gal +5
Context. Protoplanetary disks are the birthplace of planets. As such, they set the initial chemical abundances available for planetary atmosphere formation. Thus, studying elementa…
Anatomy of the Class I protostar L1489 IRS with NOEMA - II. A disk replenished by a massive streamer
M. Tanious, R. Le Gal, A. Faure +3
(abridged) Streamers are newly identified channels that transport mass from large, molecular-cloud scales down to small, protoplanetary-disk scales. To better understand their impa…
PDRs4All XI. Detection of infrared CH and CH rovibrational emission in the Orion Bar and disk d203-506: evidence of chemical pumping
Marion Zannese, Benoît Tabone, Emilie Habart +20
The methylidyne cation (CH) and the methyl cation (CH) are building blocks of organic molecules, yet their coupled formation and excitation mechanisms remain mainly unpro…
