STF 245 ALI1193.
EGG 2 Aa,Ab: This system has spectral type F2 from SIMBAD and parallax of
10.26 +/- 2.92 mas from van Leeuwen (2007). A previous orbit was VlF2007
calculated by Cvetkovic (2008) with period of 109 years and semimajor Cve2008c
axis of 0.344 arcsec. However, our new observation shows that the
system has a much shorter period and smaller semimajor axis. However,
our orbit yields roughly the same total mass, with large uncertainty.
The system appears to have executed nearly a full orbit since the
first speckle observations taken of it in 1985 by McAlister et al.
(1987). More data will be needed to confirm this orbital trajectory,
but if correct, the smaller period makes the system much more
attractive for future study. Hor2015b
