The formation process for stars
with masses several times that of the Sun is still unclear... the presence of
disks around massive young stellar objects is still uncertain... Here we report
near-infrared imaging polarimetry that
reveals an outflow/disk system around the Becklin-Neugebauer
protostellar object, which has a mass of at least
seven solar masses...

(over eight times the Sun's mass, Mo) stars remains poorly understood...
Here we report the presence of a flattened disk-like structure around a massive
15Mo protostar in the Cepheus A region...

Dear Learned
Researchers,
Forgive my
intrusion here, but star formation has now a simple model reminiscent of cosmic
and nuclear processes we know of down the line in this fractal universe of
ours. High-mass protostars become thus an essential part of star cluster
evolution. These giants are generally found in the cluster’s central region
where the high ambient pressure field could maintain their size. Your
breakthrough discoveries of such objects are indeed most reassuring; and
continued investigations should reveal this central concentration. It would
also be in keeping with what I have propounded as the true structure of the
observable universe. (Please see The Cosmos and The Galaxy for a short,
illustrative description of the formation process for galaxies and stars.)
Briefly, stellar
matter is ejected periodically from the galactic core, as in the stellar nova.
Each large chunk in the nuclear ejectum bifurcates, successively, as it moves
through the thinning pressure field away from the galactic center. The final
fragments evolve as stars, dwarfs, and planets of the cluster. Following the
formation epoch, an equatorial disk generally forms around individual bodies,
depending on their spin. It occurs by outflow (radiation wind, essentially of
protons, electrons, and electron antineutrinos, with bipolar peaks and periodic
outbursts) and inflow (fallback and accretion of matter from around) into the
gravitational well caused by the spin. (A star thus gives rise to its
circumstellar disk and never the other way around!) And,
naturally, the most massive protostars (relatively fleeting in existence, before
they splinter further) would abound while still close to their birthing pool,
the galactic hub (from which the evolving clusters with sufficient escape
velocity spiral out).
For the complete
picture, do care to check out the website www.sittampalam.net. Any comment, especially critique, would
be gratefully received.
Thank you and
best wishes,

PS: If we have the greatness of heart and the
openness of mind to consider even such opposing ‘outside' views, the true
structure of the observable universe – simple and all too obvious – will
transpire before us all much sooner than we may now think. Why not make that
sooner, possibly now, and make basic research more secure and fulfilling to
students and institutions alike; and justifiable to all concerned, including
the innocent taxpayer? Cheers!
"I found myself getting really angry,"
one cosmologist said after reading [Sittampalam's] paper.
"It must have hit some real insecurity."
