Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2024/07/29 DOI: 10.1051/0004-6361/202347574 Abstract: We present a study of hydrogen, helium, and carbon millimeter-wave radio-recombination lines (RRLs) toward 10 representative positions throughout the Orion Nebula complex, using the Yebes 40 [...]

Authors: Mulumba, D.; Knapen, J. H.; Comeron, S.; Almeida, C. Ramos; Obonyo, W. O.; Pereira-Santaella, M.; Baki, P. Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2024/10/17 DOI: 10.1051/0004-6361/202450076 Abstract: Context. Understanding how gas flows into galactic centres, fuels the active galactic nucleus (AGN), and is in turn expelled back through feedback processes is of great importance [...]

Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2024/08/13 DOI: 10.1051/0004-6361/202449604 Abstract: We investigated the role of carbon monoxide ice in the chemical evolution of prestellar cores using astrochemical rate equation models. We constrained the ratios of the binding energies on CO ice and H2O ice for a series of [...]

Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2024/02/16 DOI: 10.1051/0004-6361/202347889 Abstract: Context. Indene, a small PAH, has been detected in the gas phase in the cold dense cloud TMC-1. Due to the low temperature in the cloud, below indene condensation temperature, its presence [...]

Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2024/07/09 DOI: 10.1051/0004-6361/202450188 Abstract: Circumstellar envelopes around asymptotic giant branch (AGB) stars contain a rich diversity of molecules, whose spatial distribution is regulated by different chemical and physical processes. In the outer circumstellar layers, [...]
