Measure of the intensities and width of bright bands in stars of Classes A [[subscript]]I[[/subscript]] - O [[subscript]]II [[/subscript]].

The intensities are estimated in the following manner. The dark hydrogen lines in Sirius are assumed to be intensity 100. Since, however, I have no plate taken with 1 pr. of Sirius, in which the density seems comparable with the plates of the bright line stars, I take as my standard Sirian star, gamma Centauri as photographed on X 6293. The darkness of these hydrogen lines is called 100, and any bright line or band appearing in a spectrum [[strikethrough]] aff [[/strikethrough]] and looking as much brighter than the continuous spectrum as these lines look darker, will be called [[underline]] 100 [[/underline]].

H gamma and lambda 4059 are here sharper and better defined than the other bands. H epsilon is very wide and hazy. 4201 is nearly as intense and well defined as H gamma. H beta is rather wide. 4688 is crossed by a dark line. This is certainly seen and the position with the bright thread observed in this band on X 4115. For whereas that bright line is towards the edge of shorter lambda, this dark line is decidedly towards the edge of greater wave-length. This dark division is no darker than the continuous spectrum, and may therefore, be due to a separation in the bright band. [[end page]]

Line 4685.4 appears to be present. From this plate the lines 4697.9 and 4705.0 seem closer together than the wave-lengths imply. Probably a small correction is necessary and the lambda of 4705.1 is probably a little too great.

Determination of the wave-lengths of bands

I, I-II, II and I(a) as seen in third-type spectra by identifying the limiting solar lines.

Band I(a) seen in alpha Scorpii X and is limited by the lines 4657.0 and 4668.0, that is, the space between these lines is like a light band. This band is separated by the dark line 4663.7.

In beta Gruis X 7829, this band is more marked. The line 4663.7 is here seen also.

The other bands I, I-II and III have no well-defined limiting solar lines and these limits must be taken as determined from superposing on stars showing Orion lines (see Bk. VI pp. 82 & 83)

Band I does not extend towards red as far as lambda 4648 (as given in Part I) in alpha Orionis X 7972 or in gamma Hydri ^[[X 8323}. The bright band ends at about 4625 & a distinct bright line appears at about position of line 4630.

Lines 4201 & 4543, the additional hydrogen lines, are certainly present in this spectrum with fully as great intensity as in epsilon Orionis. The line 4649 is, however, no more intense than in beta Centauri. The lines 4089.2 & 4116.2 are intermediate in intensity between beta Centauri and epsilon Orionis. It does not make much difference whether this spectrum is classed B Pec. or B1A Pec. so the facts are stated, except that as the addit. hydrogen lines are certainly seen, it might be better to class it B, as these lines disappear in Class B1A.

15 hyd. lines are counted beyond K. They are distinctly seen except the last which appears fine and sharp at upper edge of the image but is not clearly seen at the lower. The 14th line (H sigma?) appears double.

This makes 19 hydrogen lines, the maximum in any spectrum found in this series.

Beyond line 15, there is a space without any lines and then far into the ultra-violet several well-marked lines appear.

Notes on spectral lines Line 4641.1 is very wide in Orionis, distinctly double in Crusis and Lupi, and in other stars where the lines are sharp. It is probably a fine double in all stars where it is present.

Lines 4425 & 4417 are not seen sep. on 3 prism plates but are clearly separate in Crusis 8361 (see p. 167) and in Lupi 7558.

In Gruis, line 4387 appears double, it is probable that the solar line 4383 - 4385 is present.

In Centauri the solar lines [[insert]] 4383-4385 [[/insert]] are present but not the Orion line 4387.8

Line 4361.0 is seen in Lupi 7558, Intensity 1. also appears to be glimpsed in Cruces 8261.

Notes on Miss Maury's typical stars.

alpha Virginis. Somewhat intermediate in intensities of lines bet. beta Cent. & gamma Orionis. 4116 not seen, 4089 very faint, 4649 > than 4641 but not nearly so much stronger than in beta Cent. Lines so wide on C 3 & 4 pr. plates that intensities are uncertain. From C 2611, one prism, I class it B2A.

Group IV-V of Miss Maury's classification is like B3A of mine. I found more stars with spectrum B3A than with any other Orion division. zeta Canis Majoris is one of her Group IV-V stars. It is also in my Class B3A. [[end page]]
