Table 2.
Observed and model numbers of XRBs for galaxy M83.
| XRB | Number of systems |
|||
|---|---|---|---|---|
| type | Observed | Model |
||
| 1 | 2 | 3 | ||
| LMXB | 30 | 689 (0.7) | 30 (0.03) | 30 (0.03) |
| P-LMXB | ? | 441 | 0 | 2 |
| oT-LMXB | ? | 248 | 30 | 28 |
| IMXB | 64 | 55 (0.7) | 51 (0.8) | 64 (1.5) |
| HMXB | 120 | 75 (0.3) | 116 (1.2) | 169 (4.7) |
| Total | 214 | 819 (1.70) | 197 (2.03) | 263 (6.23) |
Notes. Model 2 is a good approximation of observations in terms of the total number of XRBs as well as its observed subclasses: LMXBs, IMXBs, and HMXBs. Model 3 is closer to the observations in LMXB and IMXB numbers than Model 1 but is not as good as Model 1 due to the higher number of HMXBs. The numbers in parenthesis show the estimated number of XRBs that are predicted to end up as merging double compact objects (NS-NS/BH-NS/BH-BH). The numbers of outbursting transient LMXBs (oT-LMXBs) and persistent LMXBs (P-LMXBs) in each model are also shown.
