Was this meant to defend this statement of yours,
which you said about Algol?

The secondary [K2] spectrum could easily be a reflection
[of an B8 spectrum] from a large cool dead star or planet.
You _are_ too stupid to grasp the idiocy of this statement,
are you not? :-)
A small hot star refecting off a very large orbiting WCH could easily result in
two different spectra, B and K, shifted 180 out of phase.
So you ARE too stupid to understand the giant idiocy
in such a statement.
Pleae tell me more. Of course this would also give rise to a curve that had a
large dip something like an eclipse, for obvious reasons.
Good grief!
I must be talking to a complete moron.

this is obviously way too hard for you.

A large cool planet, orbiting a star would periodically change brightness for
the simple reason that its illuminated side would be partially hidden from an
Earth viewer by a roughly sinusoidally varying amount. When it was in line with
Earth, it could be completely dark if in an edge on orbit.

.....get it so far?

Of course its reflected spectra would contain only the lines of the star but in
considerably different proportions depending on the nature of its surface.

The planet's reflection could easily be mistaken for emission from a cooler
star since it spectrum lines would be doppler shifted 180 out of phase wrt the
star.

And the spectrum of Mars can easily be mistaken for what kind of star?

......Understand now?

Indeed. I AM talking to a complete moron.
