Orbital parameters for the narrow-lined B-type star in NGC 2004#115.
| Parameter | Value |
|---|---|
| Adjusted quantities | |
| P (d) | 2.918 ± 0.010 |
| Tp (HJD) | 2453005.45 ± 0.10 |
| e | 0.02 ± 0.02 |
| ω (deg) | 171 ± 10 |
| γ (km s−1) | 326.5 ± 2.1 |
| K1 (km s−1) | 62.4 ± 0.5 |
| Derived quantities | |
| a1 sin i (R⊙) | 3.60 ± 0.03 |
| f(m1, m2) (M⊙) | 0.073 ± 0.005 |
Notes. Period (P), time of periastron (Tp), eccentricity (e), argument of the periastron (ω) (as e is small, Tp and ω are not well constrained), systemic velocity (γ), and the amplitude or the radial velocity (K1). Derived quantities are the semi-major axis distance to the center of mass (a1) times sini, and the mass function f.
