Following Okawa, we insert operators at the boundary of regulated staralgebra projectors to construct the leading order tachyon vacuum solution ofopen string field theory. We also calculate the energy density of the solutionand the ratio between the kinetic and the cubic terms. A universal relationshipbetween these two quantities is found. We show that for any twist invariantprojector, the energy density can account for at most 68.46% of the D25-branetension. The general results are then applied to regulated slivers andbutterflies, and the next-to-leading order solution for regulated sliver statesis constructed.Comment: 24 pages, 4 figure
