MUCHFUSS项目的目标是寻找有大量看不见的伴星的sdB恒星。光度跟踪显示,在我们的样品中,RV变量系统的很大一部分是食的。伴星很可能是恒星下的,可能对sdb的形成起着至关重要的作用,但目前尚不清楚。在这里,我们建议为在短时间尺度上显示RV变化的sdb的光度跟踪运行提供旅行资金,以寻找其光曲线中的指示性特征。
英文摘要
The MUCHFUSS project aims at finding sdB stars with massive unseen companions. Photometric follow-up revealed that a high fraction of the RV variable systems in our sample are eclipsing. The companions are most likely substellar and may play a crucial role for the yet unclear formation of sdBs. Here we propose travel funds for a photometric follow-up run of sdBs showing RV variations on short timescales to search for indicative features in their light curves.
