This is the former. And they found that the eclipses were occurring half an hour later than predicted by Molnar's merger hypothesis. "The authors of the manuscript don't question our fundamental premise, which is to say 'this is something that you should be looking for, this is something that can be found,'" Molnar said. When binary star system KIC 9832227 finally merged, it was going to produce a luminous red nova - increasing in brightness 10,000-fold, which would be visible from Earth for some time. Molnar has been drawing on data from the explosion of red nova star V1309 in 2008 — a “Rosetta Stone” of sorts for predicting future similar explosions before they happen. “You won’t need a telescope in 2023 to tell me whether I was wrong or I was right,” Molnar said. KIC 9832227 is just the latest event being exploited by a chain of astrological predictions of impending doom. "It's actually because they agree with that fundamental premise that they dug deeper. This is a good example of how scientists from different parts of the world can work together to better understand how our universe works, bringing with them new pieces to the puzzle.". The telescope would not have been been able to see it. The prediction was based on the timings of minimum light – that is, the point at mid-eclipse in which the light from the binary system is at its lowest – from all available sources. The research has been published in The Astrophysical Journal Letters. Professor Molnar's exploration into the star known as KIC 9832227 began back in 2013. Big telescopes like Chile’s Atacama Large Millimeter Array (ALMA) get most of the attention — not unjustly — but it’s small telescopes that provide the advantage in scenarios like this one. KIC 9832227. This is a very close contact binary in Cygnus, which in 2017 was predicted to explode as a red nova in 2022. Exceptions … And that plot looks like this: In this graph, the horizontal x-axis is time (the date), and the vertical axis is the orbital periodContinue reading “Speedup, Slowdown, or Steady As She Goes?”, Waiting for some more bad weather to clear, so let’s talk about time … There are a handful of different time zones that are relevant to this project: Local Time: Right now, local time for me is Eastern Standard Time. But eventually a binary star is going to collide, and there are now a lot of eyes out there looking for it. "Good science makes testable predictions," Molnar said. “The project is significant not only because of the scientific results, but also because it is likely to capture the imagination of people on the street,” said Matt Walhout, dean for research and scholarship at Calvin College, in an AAS press release. Speedup, Slowdown, or Steady As She Goes? Several targets acquired which was unexpected given the weather forecast at the beginning of the night which had cloud cover increasing to 70-97% . And it wasn't just going to be a small blip in the night sky. When it comes to space phenomena, it can sometimes be hard to tell what big numbers are actually as impressive as they sound and which are not actually big at all relative to, you know, the scale of the universe. The eclipse absolutely couldn't have occurred at the time the published paper stated, either. 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. If this event is anything like the 2008 explosion, it’ll take about six months to rise to its full brightness — 10,000 times greater than the brightness of the original. A string of ‘blood moons’ in 2015 was said by US evangelicals to herald Armageddon. And so the search for an impending stellar merger continues.". A spectacular astronomical event that had been predicted for 2022 now isn't going to happen after all. Interestingly, the typo didn't occur in the article's preprint (it's the mjd, or Modified Julian Date, value in Table 6). And not much else. And they're so close that they actually share parts of their atmospheres, what is known as a contact binary. The two stars, located a mere 1,800 light-years from Earth, are currently locked in a spiralling death dance. "There have been a few other papers that have tried to poke at our project, and we've been able to poke back - criticisms that just don't fly. So it's not going to be KIC 9832227. "This is arguably the most important part of the scientific process. A binary star is actually the term for two stars which orbit one another — so close they basically share an atmosphere. We generally think they must eventually fall into each other, merge, and explode, though no one can say they must do so with certainty. Speedup, Slowdown, or Steady As She Goes.
