摘要:

本文介绍了活动食双星V405 And的多色测光和模型。0.2和0.5太阳质量的分量刚好低于和高于完全对流的理论极限,即大约0.3太阳质量。光变曲线是由恒定和可变的特征组成的:组件的扭曲形状(约25%),小日食,主要是斑点(约75%)和耀斑。

英文摘要:

We present multicolour photometry and modelling of the active eclipsing binary star V405 And. The components of 0.2 and 0.5 solar masses are just below and above the theoretical limit of the full convection, that is thought to be around 0.3 solar mass. The light curves are compositions of constant and variable features: the distorted shape of the components (about 25%), a small eclipse, and mainly of spots (about 75%) and flares.
