ASAS 014613-4656.9 = NSV 15388
The star is HD 10922
GCVS gives Hipparcos magnitudes for the range: 9.43-9.53 Hp. No type is
assigned.
Photometry in the GCPD is:
UBV system:
V= 9.341; B-V= 0.739; U-B= 0.217
uvby system:
V= 9.307; b-y= 0.461
ASAS-3 assigns EC/ESD or Ell-types.(EB, EW or Ell) and gives a period of
10.889 days.
V= 9.28-9.49
Hipparcos data converted to V gives V= 9.28-9.42.
There is too much scatter and minima may have fallen during observing gaps.
It looks like an EB-type (or EA with a lightcurve like lambda Tauri) but the
true nature remains unclear until a more accurate study is done.
Regards,
Sebastian.
