Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2023/01/01 DOI: 10.1051/0004-6361/202245492 Abstract: The previous detection of two species related to the nonpolar molecule cyanogen (NCCN), its protonated form (NCCNH+) and one metastable isomer (CNCN), in cold dense clouds supported the hypothesis [...]
Authors: Quintana-Lacaci, G.; Velilla-Prieto, L.; Agundez, M.; Fonfria, J. P.; Cernicharo, J.; Decin, L.; Castro-Carrizo, A. Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2023/01/05 DOI: 10.1051/0004-6361/202244396 Abstract: Context. Red supergiant stars (RSGs, M-init=10-40 M-circle dot) are known to eject large amounts of material, as much as half of their initial mass during this evolutionary phase. However, [...]
