Binary Option

At ... our Sun may have had a binary companion at one time. This is presented as a new theory by Harvard scientists publishing their work in Astrophysical Journal Letters (August 2020). The idea of a binary companion is not of itself new as the theory has been kicking around for a number of years. The same general idea is also central to Rupert Holms who is in the process of writing  his third lengthy book on the subject. He has spoken at SIS speaker meetings and presented his basic ideas in an article published a few years ago. However, the new study is different in that the binary companion goes back such a long way. Apart from conveniently kicked into the long grass it won't upset any of their peers as well. The new theory postulates the existence of a long lost stellar binary companion of our sun - way back at the birth of both suns. This is said to be where stars, including our sun, formed in a dense cloud of molecular gas. At the same time the Oort Cloud was formed - according to the model prediction. The model also included Planet Nine (seems it can't be buried) which the researchers think is still out there somewhere. One may wonder if their binary star companion to our sun was really a binary as it goes back to the very origins of our galaxy - or so it would appear at face value. Did it ever orbit in sync with our solar system?

At ... magnetised gas flows seem to feed a young star cluster is the headline. Observations of magnetic fields in interstellar clouds made of gas and dust indicate the clouds are strongly magnetised, and that magnetised fields within them influence the formation of stars within those clouds. This is almost electric universe stuff. Notice  the almost addition. There are still distinct differences. Magnetic fields should really be described as electro-magnetic fields but it is interesting to know scientists are actively investigating them. The research shows that not all dense filaments are equal. In some of the filaments the magnetic field appears to succomb to the flow of matter and is pulled into alignment with the filament. They continue by saying gravitational force takes over the dense section of filaments resulting in a weak magnetised gas flow which is able to feed the growth of young stellar clusters. They liken this to a conveyor belt of new stars.

We are then told that it is understood from theoretical simulations and from observation that the filamentary nature of molecular clouds actually plays a major role in channelling mass from the larger interstellar medium into young stellar clusters whose growth is fed from the gas.The  formation and evolution process of stars is as yet not understood - but several fundamental forces are thought to play a role.
