In the figure on the left, the smaller star has a Roche lobe filling factor of 0.5, while the larger star has a Roche lobe filling factor of 1.0. This means that the large star is just big enough for gas to fall onto the smaller star. In the middle figure, both stars have a Roche lobe filling factor of 1.0, so they just barely touch in the middle. In the figure on the right, the stars have a Roche lobe filling factor larger than one, so they have actually merged into a single object.}}{3}} \newlabel{roche}{{3}{3}} \@writefile{toc}{\contentsline {section}{\numberline {3}How to Use Nightfall}{3}} \@writefile{toc}{\contentsline {subsection}{\numberline {3.1}Overview}{4}} \@writefile{toc}{\contentsline {subsection}{\numberline {3.2}Figuring out the Right Parameters}{7}} \@writefile{toc}{\contentsline {section}{\numberline {4}Publication}{7}}
