The faint but clear companion at 57mas is not the known SB2 system |
|
|
(P=3.8d, a sin i = 16Rsun), which is separated by 0.07mas assuming a |
|
|
distance of 1 kpc (Trepl et al. 2012, MNRAS 427, 1014). Moreover, the |
|
|
SB2 has nearly equal masses, while the resolved pair has dH=3.4, |
|
|
pointing to quite different masses. The object is also detected in X |
|
|
rays. Trepl et al. identified a soft X-ray excess and 10sec pulsation |
|
|
which they interpret as the signature of a neutron star in the system. |
|
|
Our detection is probably an active later-type object, which may |
|
|
provide an alternaitve explanation to the X-ray excess. |
