Optically thin HC3N/HC5N isotopologues yield 12C/13C ≈ 37 (≈48 after fractionation correction) in G+0.693, matching 3–5 kpc disc gas and implying bar-driven inflow into the CMZ.

Asteroseismic ages from TESS calibrate [Y/Mg] and [C/N] chemical clocks, revealing a radially dependent [Y/Mg]-age relation that is steeper in the outer Galactic disc and flatter inward, with NLTE corrections and evolutionary stage accounting required for accuracy.

High $^{12}$C/$^{13}$C isotopic ratios toward G+0.693-0.027: evidence for gas inflow to the Central Molecular Zone
