New low-mass eclipsing binary from SDSS-II

Listed in IVOA Registry (Virtual Observatory)

We present observations of a new low-mass, double-lined eclipsing binary system discovered using repeat observations of the celestial equator from the Sloan Digital Sky Survey II.

Description

Using near-infrared photometry and optical spectroscopy we have measured the properties of this short-period [P=0.407037(14)days] system and its two components. We find the following parameters for the two components: M_1_=0.272+/-0.020M_{sun}_, R_1_=0.268+/-0.010R_{sun}_, M_2_=0.240+/-0.022M_{sun}_, R_2_=0.248+/-0.0090R_{sun}_, T_1_=3320+/-130K, and T_2_=3300+/-130K.

The masses and radii of the two components of this system agree well with theoretical expectations based on models of low-mass stars, within the admittedly large errors.
