LEH 1 |
Lehmann et al. (2016) find that KIC 7177553 is a quadruple system, |
|
|
consisting of two close binaries of nearly equal magnitude, separated |
|
|
by about 0.4". They estimate the distance to the quadruple as 406 +/- |
|
|
10 pc, giving a physical separation of the wide pair 167+/- 5 au and |
|
|
an orbital period >1000y. One close pair is an eclipsing binary with |
|
|
orbital period 18.00d. The other pair is an SB with period 16.5d. All |
|
|
four stars are of similar mass and spectral type (main-sequence G). |
