Abstract:
Accurate absolute properties are determined for the first time for the
3.15 day period eccentric eclipsing binary star FT Ori based on new
absolute photometry, five differential light curves, and a radial
velocity curve. The stars appear to be normal for their spectral
types, A0+A2. The orbit is highly eccentric (e=0.409) and shows
apsidal motion with a period of 536-years. The absolute properties and
the degree of central mass concentration of the stars are consistent
with current theoretical models at an age of 190Myr.
