Results of fitting one of the simulated data generated in the gravastar 3 with GRAVITY+ uncertainties for the best-fitting metric (the gravastar 3 model) and in the fluid sphere 2 model.
| Metric | χred2 | r [rg] | i [°] | φ0 [°] | lp | Kcoef | Spin |
|---|---|---|---|---|---|---|---|
| Gravastar 3 | 1.23 | 8.14 ± 0.04 | 157.1 ± 0.3 | 15.0 ± 0.7 | 0.42 ± 0.01 | 0.99 ± 0.01 | 0 (fixed) |
| Fluid sphere 2 | 1.32 | 8.35 ± 0.09 | 155.7 ± 0.3 | 15.4 ± 0.6 | 0.40 ± 0.01 | 1.02 ± 0.02 | 0 (fixed) |
Notes. These two models are shown with the simulated data in the figure above.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
