Abstract:
UBVRCIC photometry of the W UMa eclipsing binary FI Bootis has
been obtained and analyzed simultaneously with previously published
photometry and radial velocities. The analysis of the light and radial
velocity curves shows that the system is an A-type W UMa system
consisting of stars with masses 0.82 and 0.31M☉.
Description:
We initially obtained UBVRCIC measures on five nights in 2004 at
Lowell Observatory. These were followed by a comprehensive set of BVIC
observations on 16 nights in 2005 obtained at the Sonoita Research
Observatory (SRO) located in Sonoita, Arizona.
