Precise mass and radius measurements for the components of the bright solar-type eclipsing binary star V1094 Tauri

Autor: R. J. Hutcheon, J. V. Clausen, Claud H. Sandberg Lacy, Barry Smalley, Guillermo Torres, Laurence A. Marschall, John Southworth, Pierre F. L. Maxted, Krešimir Pavlovski

Publikováno v: Astronomy and Astrophysics

Absolute dimensions of eclipsing binaries

Autor: John Southworth, J. V. Clausen

Publikováno v: Astronomy & Astrophysics. 461:1077-1093

DW Carinae is a close but detached early B-type eclipsing binary in the young open cluster Cr 228. We have measured accurate physical properties of its components (masses and radii to 1%) and used these to derive the age, metallicity and distance of
