Azimuthal molecular variations in the AB Aur planet-forming disk
Haochang Jiang, Dmitry Semenov, Myriam Benisty +5
Late infall episodes are emerging as an important driver of disk evolution. Observed as filamentary streamers in molecular lines and scattered light, such accretion perturbs disk s…
Chemical study of two starless cores in the B213/L1495 filament
L. Moral-Almansa, A. Fuente, M. RodrÃguez-Baras +7
The chemical evolution of pre-stellar cores during their transition to a protostellar stage is not yet fully understood. Detailed chemical characterizations of these sources are ne…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?
I. MendigutÃa, N. Huélamo, I. Jiménez-Serra +32
The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…
Observations of sulfuretted species in HL Tau
P. Rivière-Marichalar, R. le Gal, A. Fuente +4
Protoplanetary disks inherit their chemical composition from their natal molecular cloud, but the extent to which this material is preserved versus reset through chemical reprocess…
A quest for sulfur-bearing refractory species. Identification of CaS in the interstellar medium
A. Tasa-Chaveli, Ã. Sánchez-Monge, A. Fuente +10
The recent detection of refractory molecules in massive star-forming regions provides a means of probing the innermost regions of disks around massive stars. These detections also…
Gas-phase Elemental abundances in Molecular cloudS (GEMS) XI. The evolution of HCN, HNC, and N2H+ isotopic ratios in starless cores
A. Tasa-Chaveli, A. Fuente, G. Esplugues +5
Isotopic ratios have been used as chemical diagnostics to investigate the origin of the material in the Solar System. We have determined the HCN, HNC, and N2H+ isotopic ratios and…
