Looking for Tidal Interaction expert

Hi All

I'm looking for help with finding info on the tidal bulge lag angle (TBLA)
on an idealized primary from various secondaries (actually, the system I am
interested in is the Sun as primary and the planets as secondaries. I'm
assuming that the Sun would be fairly close to an idealized primary, no
nasty continents or oceans to worry about).

I have found several references that state that the TBLA = 1/Q were Q is the
dissipation function. I would expect that Q is dependent on a bunch of
material properties of the Sun, but I would also expect that it depends on
the rotational period of the primary and the orbital period of the secondary
(this is the bit I'm really interested in). That is, I would expect the TBLA
for one secondary to be different from the TBLA for a different secondary if
their orbital periods differ.

Is this a reasonable expectation?

Does anyone know/know of the relationship between Q and P_rot(primary) and
P_orb(secondary)?

If someone could suggest a text that has a good treatment of such matters,
it would be greatly appreciated.

Thanks
