Almost 2.5 years ago on page 40 I explained how planets formed along side the Sun's formation process prior to its ignition.
I'm going to be brief on this page as it seems to me the point need not be hammered home when it is so obvious a 10 year old can understand it's logic.
Tau's are very young (pre-star ignition) developing solar systems.
This article explains how the current solar system formation theory goes.
CI Tau is about 500 light years away in a very active part of the galaxy termed a “stellar nursery.”
At only 2 million years old, CI Tau is a mere infant in stellar terms. Our own Sun is about 5 billion years old and has another 5 billion to go, give or take.
So CI Tau is too young to have the type of gas giants that it has. Or so we thought.
Another quote from the article
Our best model of solar system formation is called the nebular hypothesis and goes something like this: A swirling cloud of gas and dust grows and gains density until it collapses into a star and fusion starts. Around this newly-formed star, the remainder of the gas and dust keeps swirling as a protoplanetary disc. Over time, this matter clumps up and forms other planets, moons, and asteroids, and there’s no more protoplanetary disc.
The sequence here is that a gas cloud nebulae first collapses into a star then after the star ignites, moons and planets form.
Brown Dwarf stars are only about 13 times the mass of Jupiter.
CFHT-BD-Tau 4 is a brown dwarf star in the Taurus region of space with forming young (less than a million years) planets.
This is nonsense.
Our planets were in the process of forming before the Sun ignited.
The planets were forming along with and at the same time our Sun was forming just like Jupiter accreted material into the Galilean moons so too a pre ignition proto-star accretes material into orbital zones creating planets prior to its ignition.
This process can be seen taking place in the rings of Saturn as the moon's Pan, Atlas and Daphnis form from debris in the rings as they clear empty bands.
