V892 Tau. |
|
|
Circumbinary disk approximately five times larger than the binary |
|
|
separation. |
Mnr2008 |
|
Total mass estimated to be 6.0 +/- 0.2 \msun. Orbit is nearly coplanar |
|
|
with circumbinary disk. Mild inner and outer disk misalignment may be |
|
|
due to interaction with the eccentric binary. |
