Definition of a dusty source.
| Doppler-shifted Brγ | NIR/MIR continuum | |
|---|---|---|
| Emission | Yes | magNIR ≤ magMIR |
| Remarks | Keplerian orbit | |
Notes. Because the majority of objects in the NSC can be classified as main-sequence stars, the photometric requirement magNIR ≤ magMIR is a necessary condition. Similarly, the detection of a Doppler-shifted Brγ emission line is, despite the limitations imposed by the field of view of SINFONI, a necessary condition. As shown in Peißker et al. (2020a), the presence of some additional emission lines, such as the forbidden iron line [FeIII], can vary for individual sources.
