Abstract:
We present new V-band differential brightness measurements as well as
new radial-velocity measurements of the detached, circular, 0.84-day
period, double-lined eclipsing binary system, CV Boo. These data,
along with other observations from the literature, are combined to
derive improved absolute dimensions of the stars for the purpose of
testing various aspects of theoretical modeling.
Description:
New differential brightness measurements of CV Boo were obtained with
the facilities available at the Kimpel Observatory.
Observations consisted of 60s exposures through a Bessell V filter
(2.0mm of GG 495 and 3.0mm of BG 39).
