Absolute properties of CM Dra
Listed in IVOA Registry (Virtual Observatory)
In this paper, we present a complete reanalysis of the eclipsing systems, CM Dra, composed of two dM4.5 stars.
Description
New and existing light curves as well as a radial velocity curve are modeled to measure the physical properties of both components. The masses and radii determined for the components of CM Dra are M1=0.2310+/-0.0009M_{sun}_, M2=0.2141+/-0.0010M_{sun}_, R1=0.2534+/-0.0019R_{sun}_, and R2=0.2396+/-0.0015R_{sun}_.
With relative uncertainties well below the 1% level, these values constitute the most accurate properties to date for fully convective stars.
