Blinded by the light: on the relationship between CO first overtone emission and mass accretion rate in massive young stellar objects

J. D. Ilee, R. D. Oudmaijer, H. E. Wheelwright +1

To date, there is no explanation as to why disc-tracing CO first overtone (or `bandhead') emission is not a ubiquitous feature in low- to medium-resolution spectra of massive young…
