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 ...

If the insulating crust were removed, the trapped heat will quickly scorch and melt our bodies. Can the heat t ...

Relativity and the Gravitational Potential of the Universe

Velocity time dilation appears unrelated to gravitational time dilation because of this, and has led to certain cou ...
