我们已经发现了一个新的,接近相等的质量,食M矮双星从下一代过境调查。该系统是已知的三个视场年龄(>1 Gyr)的晚M矮星食双星之一,周期为1.74774 d,与CM Dra和KOI 126相似。对食和视向速度的模拟表明,分量质量为Mpri =M,Msec=M,半径为Rpri =R,Rsec=R。有效温度为K和K,与M5矮星一致,与主序星模型基本一致。这一对代表了一个有价值的补充,可以用来限制恒星序列低质量端的质量-半径关系。
We have discovered a new, near-equal-mass, eclipsing M dwarf binary from the Next Generation Transit Survey. This system is only one of three field-age (>1 Gyr), late M dwarf eclipsing binaries known, and has a period of 1.74774 d, similar to that of CM Dra and KOI126. Modelling of the eclipses and radial velocities shows that the component masses areMpri=M⊙,Msec=M⊙; and the radii areRpri=R⊙,Rsec=R⊙. The effective temperatures areK andK, consistent with M5 dwarfs and broadly consistent with main-sequence models. This pair represents a valuable addition that can be used to constrain the mass–radius relationship at the low-mass end of the stellar sequence.
