LOAO BV-bands photometry and BOES RVs of WASP 0131+28

We report the first BV light curves and high-resolution spectra of the post-mass transfer binary star WASP0131+28 to study the absolute properties of extremely low-mass white...本研究首次报道了经质量转移后的双星WASP0131+28的BV光变曲线（BV light curves）与高分辨率光谱（high-resolution spectra），旨在探究极矮质量白……的绝对物理性质。
