International team of astronomers discovers two rare binary star systems

An international team of astronomers has identified only the second and third examples of a rare type of star system comprising two central stars orbiting each other, encompassed by a remarkable disk of gas and dust.

“If there were a planet in one of these systems, it would be like the planet Tatooine from Star Wars,” says Michael Poon, a Ph.D. student in the Faculty of Arts & Science’s David A. Dunlap Department of Astronomy & Astrophysics and one of two University of Toronto researchers involved in the discovery.

“You would see two suns in the sky orbiting each other. In addition, there’s a disk around the stars. Picture Saturn’s rings but much, much larger—with the stars in the middle.”

Such disks are referred to as protoplanetary disks because they eventually form into families of planets like our solar system. The newly discovered systems are rare because their disks lie at an angle to the orbits of their central stars.

“The discovery of objects like these is important for our understanding of planet formation,” says J.J. Zanazzi, a postdoctoral fellow in the faculty’s Canadian Institute for Theoretical Astrophysics (CITA). “Planets are born from them so the existence of disks around binary stars shows it’s likely we will find more planets orbiting binaries.

"They’ll also help us understand whether life can exist on a planet that orbits a binary star at an angle because of how that orientation affects temperature and other conditions.”

The discovery of the new objects, designated Bernhard-1 and Bernhard–2, is described in a paper being published July 4 in The Astrophysical Journal Letters.

The lead author is Wei Zhu from Tsinghua University, Beijing, formerly a postdoctoral fellow with the Faculty of Arts & Science’s Canadian Institute for Theoretical Astrophysics (CITA). Zanazzi and Poon are U of T co-authors.

Bernhard-1 and Bernhard-2 are so distant, we can’t see their two central stars individually (such pairs of stars are known as binary stars). Instead, we only see a single point of light and measure the total brightness of the binary.

The researchers identified the new objects by analyzing the complex and distinctive variations in brightness caused by their unusual geometry. A graph of those variations over time is referred to as a light curve and the light curves of the new systems match that of the first such system ever discovered—an object referred to as Kearns Herbst 15D (KH 15D).

The light curves of Bernhard-1 and Bernhard-2 dip to a fraction of their peak brightness—the former for 112 days every 192 days; the latter for 20 days every 62 days. These dips are the sign that one of the stars in each binary is moving behind the disk as seen from Earth. When the star re-emerges, the brightness of the system returns to normal.

Also, when the co-authors compared recent observations with archival data going back decades, they found that both objects varied in brightness over much longer periods. Previous analysis of KH 15D by Poon, Zhu and Zanazzi, along with the work of other researchers, concluded that this long-term pattern revealed that the disk and stars were at an angle to each other.

Because binary stars and their protoplanetary disks condense from the same vast, spinning cloud of material, the disk typically lies in the same plane as the orbits of the stars—just as the orbits of most of the planets and moons in our solar system lie on the same plane. Imagine two figure skaters, holding hands, twirling around each other while other skaters circle the pair; all are skating on the same plane of the surface of the ice.

But KH 15D, Bernhard-1 and Bernhard-2 are rare in that their circumbinary disks are at an angle to the planes of the orbiting stars. Because of this tilt, the disks wobble like a spinning top, a motion referred to as precession, as they move between us and the stars, causing the light of the central stars to dim. For KH 15D, that cycle of dimming could take anywhere from 60 to 6,000 years.

The two types of variations in brightness combine to create the signature light curve of KH 15D-like objects.

The discovery of Bernhard-1 and Bernhard-2 was made when Klaus Bernhard, an amateur astronomer and member of the Bundesdeutsche Arbeitsgemeinschaft für Veränderliche Sterne, analyzed data from the Zwicky Transient Facility. The ZTF’s instrument surveys the entire northern sky every two days, providing data for countless objects over long stretches of time.

Combing through the data, Bernhard uncovered KH 15D-like candidates. He then shared his findings with Poon, Zanazzi and Zhu whose further analysis revealed Bernhard-1 and Bernhard–2.

Now that the researchers have found two more of these rare celestial objects, they are optimistic more discoveries will follow.

“Just this month, Gaia released its most recent data,” says Zanazzi of the space mission that has been observing a billion stars in the Milky Way Galaxy since its launch in 2013. “And now that we have this model for these objects, we’re hopeful we can use it to find more objects to add to the list.”

“We’re also hopeful more observers will look at Bernhard-1 and Bernhard–2 for longer periods,” says Poon. “We’re lucky that KH 15D has been observed at a special time where its orientation causes the light of the central stars to dim. We’re confident that Bernhard-1 and Bernhard-2 also exist in this favorable orientation, so having more observations will increase our understanding of these rare objects.”

“Are you fucking her?”

Katsuki stands. With a slow, deliberate movement, he places both hands on the table and leans forward, those vermilion eyes finding yours in an unblinking stare.

“You wanna repeat that?” his lip arches in disgust, “Because I’m pretty sure I misheard you.”

Your heart beat buzzes across your skin. Anxiety eats at you, but the anger and pain pushes you forward. “Are you fucking her?" 

Bakugo doesn’t move, but the vein on his jaw grows more defined as he grinds his teeth together. "Why would you ask me that?”

“You’re not saying no.”

The chili plant made a deal with their God to only be consumed by things that could spread its seeds and fly. The chili received capsaicin, making itself painful to eat for mammals, but not birds, and all was well for the chili.

Then the human shows up, tastes it, and likes the pain. So now there's this flightless fucking mammal eating the chili. Like not even a fruit bat or anything, a flightless fucking mammal chomping on the chili.

What the fucking shit, God, cried the chili, I specifically requested the opposite of this.

Now hold on, wait a moment, replied the God who talks to plants but has no idea what the fuck these apes are going to do next. It might be something cool.

And in a flash of a second, in barely fraction of the time that chili took to develop capsaicin, the humans went from walking across land bridges and rowing little boats across small waters, into building ships that could cross oceans. More humans tasted the chili, and liked the pain. They took the seeds with them, and planted it elsewhere.

See? They spread the seeds.

They're still not flying, said the chili, still feeling insulted and betrayed.

But before the conversation was over, the humans were still not done fucking around and nowhere close to finding out. The ships became machines, and another machine was invented, capable of flight. Now, not only were the humans farming chili on continents far too far away for any of the birds that originally ate it could dream of flying, but the chili flew with them to lands where it could possibly not grow, so that humans over there could also eat it and enjoy the pain.

You see? They spread your seeds and fly.

It doesn't count as keeping a promise if you only manage it by a fucking accident, said the chili, still somewhat insulted. But nonetheless, the chili thrived.

a/n: just realised i put two different movies in itadori's one, just go with "train to busan" pls :((

God, I can't tell you how much the "there's not enough enrichment in my enclosure" joke has helped my mental health. Because, for some reason I can't comprehend, pretending that I'm a zoo keeper caring for an animal (which is also me) just makes everything easier to comprehend. Like "Your head gets screwey when you're apartment is messy" just doesn't carry as much resonance as "The tiger becomes agitated when its enclosure is cluttered" because then I'll be like, no shit? The tiger? I've gotta keep things nice and clean for the tiger.

not pulisic sacrificing his ability to have children for a goal

been thinking about this for the past half hour.

the comment section is a joke but i got nothing
