My recollection of rotation curves is such as those shown by Kent
(Figure 1, URL:
http://adsbit.harvard.edu/cgi-bin/np...J.....93..816K
).


NV This document at page 5 = page 821 shows the following sentence:
NV "In principle, the bulge and the disk must be treated differently
NV since they contribute in different ways to the rotation curve" Why
NV differently ? What is meant with: "different ways" In principle
NV the rotation curve at each distance r from the center of the
NV galaxy depents on the mass dm at each position x,y,z

I don't have my copy of Binney & Tremaine in front of me, but I have a
dim recollection that the gravitational potential of a disk is
different than that of a spherical distribution. That has an impact
on the rotation curve. See
URL:http://www.astro.su.se/%7Epawel/gradprobl.2.html for examples.

NV Next they write: "Also they are likely to have different M/L
NV ratios" Why ?

NV IMO it is not so strange that M/L ratios are different but if that
NV is the case and when there is a disk it becomes more difficult to
NV calculate the mass of the disk accurately.

The stars are different. Bulges are dominated by low-mass stars,
comparable to the Sun. Most of the light from a disk comes from the
high-mass stars (which are absent in a bulge), but the high-mass stars
contribute very little to the overall mass of the disk. (A 10 solar
mass star might have a luminosity of 100 solar luminosities.)

Does that have anything to do with the Muppet storey "Pig Lips Now"?

What does this remind you of?


It remind me that my unified quantum theory about the Universe can be
the solution. Please read the following and my treatise.


OK. Since you have a unified quantum theory about the universe,
could you please calculate the decay rate of 10C for me and show
the calculation? Thank you.

Dear Abhi,

This newsgroup is filled with crackpots and my rubber hose is not
long enough to reach. Where can I obtain some C4 and a box that will
ship it safefly to where you are typing? Just sign me,

Sane people everywhere

I really don't understand what the hell is going on in this NG. People like
josX keep coming, firing like hell on Einsten and just vanish or fade away.
I have yet to see some person who has taken something valuable from this NG
which is accepted by establishment.

It is just one and half year for me in this NG and I am terribly bored. I
just don;t understand how you people stay for so long time.

Tell me the secret, Paul.

Bilge, I call my Quantum Theory about The Universe a 'unified theory'
because it connects physical quantities from macrocosmos and
microcosmos. The Theory gives a unification of the smallest with the
biggest.
