The Effect of Continuous Balmer Absorption upon the Equivalent Widths of Stellar Absorption Lines.
Abstract
Continuous Balmer absorption on the violet side of X 3647 tends to weaken the ab- sorption lines of various elements. From the equivalent widths of 48 lines of Ti ii the ratio of the continuous absorption coefficients on both sides of X 3647 is found to be i6 in ~ Leonis, io in a Cygni and a Lyrae, and 2111 v Sagittarii. The hydrogen abundance is very great in ~ Leonis, a Cygni, and a Lyrae but is surprisingly low in v Sagittarii
