Estimate of mass loss rate from X-ray luminosity and characteristic radii of J12270.
| Parameter | High mode | Low mode | Quiescence |
|---|---|---|---|
| LX(0.3−10 keV) (erg s−1) | 4.2 × 1033 | 6.2 × 1032 | 1.1 × 1032 |
| Ṁ (g s−1) | 2.3 × 1013 | 3.3 × 1012 | –( * ) |
| rm ( † ) (km) | 105 | 181 | –( * ) |
| rc ( * *) (km) | 24 | 24 | 24 |
| rlc (km) | 80 | 80 | 80 |
| State (propeller/ejection model) | Propeller | Radio-ejection | Radio pulsar |
Notes. We assume B ∼ 1.36 × 108 G (Roy et al. 2015). ( † )Derived as LXR/GM, where M and R are the NS mass and radius, G is the gravitational constant; ( * )we do not compute Ṁ and rm for the quiescent state because the X-ray luminosity is not related to mass accretion; ( * *)rc is the corotation radius.
