Integrated MIRI-MRS spectrum of HK Tau A (top) and B (bottom) in grey. The black line represents the continuum baseline. Insets in the top panel zoom into wavelength regions that shows molecular emission from ¹²CO, H₂O, ¹²CO₂, and H₂. The shaded bands in the bottom panel indicate the main ice absorption regions. H₂ rotational lines are marked with blue ticks, and gas emission features are labelled where present.
