No actual lightcurves linked from either of those, alas.

What I thought of was that it might make it rather easy to
see the 'E' component in my Pronto, something that has eluded me
thus far (though without much effort). Yeah, I know, photometry,
blah blah, but this one piques my interest.
Speaking of the E component, George Herbig and Roger Griffin
just published a very nice paper about this star. I note that these
guys are aged 86 and 70+, respectively. Using new Keck spectra,
they find the star is a close binary that are apparently still
contracting onto the main sequence. The stars are identical in
type, something like mid-G giants, and appear brick-red in a
large-enough telescope---reddened a bit more than the four main
Trapezium stars. Herbig & Griffin actually cite Lord Rosse to this
effect, typical of Griffin's extremely thorough bibliographies in
any paper he authors/co-authors.
