Abstract
This reading is part in a series on the Azimuthally Symmetric Theory of
Gravitation (ASTG) set-out in Nyambuya (2010a). This theory is built on Laplace-
Poisson’s well known equation and it has been shown therein (Nyambuya 2010a) that the
ASTG is capable of explaining – from a purely classical physics standpoint; the precession
of the perihelion of solar planets as being a consequence of the azimuthal symmetry
emerging from the spin of the Sun. This symmetry has and must have an influence on the
emergent gravitational field. We show herein that the emergent equations from the ASTG
– under some critical conditions determined by the spin – do possess repulsive gravitational
fields in the polar regions of the gravitating body in question. This places the ASTG
on an interesting pedal to infer the origins of outflows as a repulsive gravitational phenomena.
Outflows are an ubiquitous phenomena found in star forming systems and their true
origins is a question yet to be settled. Given the current thinking on their origins, the
direction that the present reading takes is nothing short of an asymptotic break from conventional
wisdom; at the very least, it is a complete paradigm shift as gravitation is not at
all associated; let alone considered to have anything to do with the out-pour of matter but
is thought to be an all-attractive force that tries only to squash matter together into a single
point. Additionally, we show that the emergent Azimuthally Symmetric Gravitational
Field from the ASTG strongly suggests a solution to the supposed Radiation Problem
that is thought to be faced by massive stars in their process of formation. That is, at
8 - 10M , radiation from the nascent star is expected to halt the accretion of matter
onto the nascent star. We show that in-falling material will fall onto the equatorial disk
and from there, this material will be channelled onto the forming star via the equatorial
plane thus accretion of mass continues well past the curtain value of 8-10M albeit
via the disk. Along the equatorial plane, the net force (with the radiation force included)
on any material there-on right up-till the surface of the star, is directed toward the forming
star, hence accretion of mass by the nascent star is un-hampered.
