Rare Planet Found Orbiting Three Stars

...the dusty disk around a newly-forming planetary system at GW Ori, a system 1,300 light-years away from the sun. GW Ori is what’s known as a hierarchical triple star system, meaning that two stars orbit each other with a third orbiting around the pair...

There is a vidya embedded in the story above:  But it is about some other star system that has 9 planets or something orbiting a red dwarf some 40 light-years from here; (for those with reading comprehension difficulties).

The photograph instantly reminded me of Larry Niven's "The Smoke Ring" & "The Integral Trees" books that he has yet to write a third book about to make a trilogy.  I have been patiently waiting about 25 years for the guy to do so, I imagine he will die before that happens.  Much like his writing buddy J. Pournelle did before completing the third "Jannisaries" book.

Anyhow, the orbital mechanics there are pretty cool looking.  I was unable to determine if the gas giant orbiting the three sun system was doing so on an orbit that encompasses all three stars or just the primary pair.  Surely, theythe hobo elite know that important bit of information?

I found a vidya about the weird triple-star planetary system:



I feel better now that I am not the only one to find it remarkable.  Still not clear where exactly the planet is assumed to be orbiting, although this guy does emphatically state that it orbits all three stars.  Maybe I missed that part?



ediot:  HAH!  And there on the preview photo above the orbit location is clearly depicted.

This is an interesting one to look out for in the coming year(s):

Hold on to Your Butts, This Binary Star Is About to Explode

A model for predicting exactly when a binary star will merge and explode has a literal one-in-a-million chance of being accurate — it’s never been done before. But Calvin College professor Larry Molnar and his colleagues...

By Professor Mjölnir's theory, it is set to go 'splodey sometime next year.  Approximately in the constellation Cygnus;  and if it goes will be big Wampum.  You can Trust the Science, hear?

KIC 9832227: Using Vulcan Data to Negate the 2022 Red Nova Merger Prediction

...Abstract

KIC 9832227 is a contact binary whose 11 hr orbital period is rapidly changing. Based on the apparent exponential decay of its period, the two stars were predicted to merge in early 2022 resulting in a rare red nova outburst. Fortunately KIC 9832227 was observed in 2003 as part of the NASA Ames pre-Kepler Vulcan Project to search for transiting exoplanets. We find that the Vulcan timing measurement does not agree with the previous exponential decay model...

It seems that you can trust whatever Science you prefer in this instance, luckily Astrophysical Dynamics are really complex (not like the dynamics of treating the common cold with mRNA which is kindergarten stuff) so there is plenty of room for all sorts of opinions, predictions, random guesses &c...

Settle down, fellow Scientists!

Two stars will NOT merge and explode into red fury in 2022

...It's time to face a hard truth. Good science is mostly about meticulously testing informed predictions. And, sadly, these predictions often fall flat...

Clearly, a veritable consensus has been Scientifically arrived at that will stand forever irrespective of what actually happens.  You can take that to the bank!

On that note, I am taking side-bets on whether or not the Earth will survive the next year.  PM me for the latest line with your PayPal information.

For those of you that are illiterate, hear:





Above are no fewer than two vidya arguments from both sides, they are both dated (see vidya descriptions for deets)!

Bonne année, mes amis!

I can't decide if this guy is a Russian or a Ukrainian.



He seems legit...
