HD 66051, an eclipsing binary hosting a highly peculiar, HgMn-related star

open access: yesScientific Reports, 2017
HD 66051 is an eclipsing system with an orbital period of about 4.75 d that exhibits out-of-eclipse variability with the same period. New multicolour photometric observations confirm the longevity of the secondary variations, which we interpret as a ...
