Anomalously high deuterium fractionation in a galactic translucent cloud: a challenge to chemical models
Gan Luo, Zhi-Yu Zhang, Thomas G. Bisbas +8
Deuterated (D-) species have long been proposed to diagnose the physical conditions and chemical evolution of cold dense molecular clouds. While deuterium fractionation has been ex…

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…
