Non-conservative mass transfers in Algols
... (2001). In this study, 18 of these Algols, showing only parabolic O−C diagrams, were selected in order to investigate their orbital period changes and apply the revised model of non-conservative mass transfer. The SD parameter in Table 1 is a crude probability indicator for binaries having an SD nat ...
