大質量偏心雙星系統 MACHO 80.7443.1718 的極端光變現象並非先前研究所認為的由潮汐力或 Be 星現象引起,而是強烈的恆星風與伴星相互作用的結果。

“The combination of atmospheric eclipse with excess emission from the WWC cone can satisfactorily explain the amplitude and shape of the light curve, which previous models were unable to do.”
“In this scenario, ExtEV is an extremely rare example of a massive binary system during a short but dramatic stage in its evolution, when the proximity of a massive companion leads to a sudden stripping of the primary’s envelope without the need for RLOF.”
