cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomyphotometryradial-velocityIn this paper, we present a complete reanalysis of the eclipsing systems, CM Dra, composed of two dM4.5 stars. 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.2009ApJ...691.1400Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/691/1400CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/374/164 : BH Cas VRI differential magnitudes (Zola+, 2001)J/A+A/387/850 : Radial velocities of eclipsing binaries (Imbert, 2002)J/other/IBVS/5438 : 162-nd list of minima of eclipsing binaries (Diethelm,J/AJ/135/850 : Properties of eclipsing binaries found in TrES (Devor+,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/691/1400https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/691/1400http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/691/1400https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/691/1400https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/691/1400http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/691/1400GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/691/1400/table4Radial velocity measurements for CM Dra in the heliocentric framerecnoRecord number assigned by the VizieR team.
