ALMA Observations of CO Isotopologues Towards Six Obscured post-AGB Stars
Low- and intermediate-mass stars evolve through the asymptotic giant branch (AGB), when an efficient mass-loss process removes a significant fraction of their initial mass.

JOYS+ Study Of Solid State 12C/13C Isotope Ratios In Protostellar Envelopes: Observations of CO and CO2 Ice with JWST
The carbon isotope ratio is a powerful tool for studying the evolution of stellar systems. Recent detections of CO isotopologues in disks and exoplanet atmospheres pointed towards significant fractionation in […]
