Costas will form for the first time tandem holder with Aidoo

first_imgEI Celtic 2020 begins with the defense in frame. Oscar Garcia He has found himself in the lap of training with only four defenses available to receive Osasuna on Sunday. The losses in the rear will cause a duo of centrals to open. David Costas will first form a tandem holder with Joseph Aidoo.The youth has only played two games since the beginning in this first round. It started The league entering eleven to face the Real Madrid and the coaching staff of the García Junyent brothers He opted for the first time for the chapeleiro on the day before the Christmas break. Costas played the 90 minutes in the City of Valencia, where Celta used a scheme with three centrals, and was one of the players signaled by the defeat against the I raised. During the first part he kept the fighter at bay Roger Martí, but after the break he was unarmed, like his two companions in the axis of the rear, by the attacking granotas. The new year will start for the player trained in To Madroa with the opportunity to compensate. Néstor Araujo will not be able to participate before Osasuna when completing the card cycle, while Jorge Sáenz continues to leave after damaging his left shoulder in the cupping match with Peña Azagresa.Mal. Only two exchanges are suitable and, for the moment, also two sides: Kevin Vázquez and Lucas Olaza. The other two lanes should arrive to measure the reds. David Juncá has partially restarted training with the group and Hugo Mallo will be 2-3 days more exercising on the sidelines due to muscle strain.last_img read more

How a planet could survive a collision between its two suns

first_imgWhile searching for Earth-like planets, NASA’s Kepler spacecraft has come across 10 that share one very un-Earth-like quality: They orbit two stars, instead of one. The worlds are aptly named “circumbinary planets” (“circum” meaning around, and “binary” referring to two objects), and in this type of binary system, the two stars orbit each other while the planet orbits the two stars (pictured above). But only the lucky binaries seem to have planets that orbit them; some stellar binaries that lack orbiting bodies have a different third party—a distant star that’s so massive, its gravitational fluxes actually change the orbit of the stellar binary, causing the two stars to shrink together in a process called orbital decay. If left uninterrupted, the stars will eventually collide together in a violent, calamitous explosion. Now, astronomers have asked a new question: What would happen if a circumbinary planet were in the mix? Naturally, one assumes its inevitable, fiery demise. But findings, published online 9 July in the Proceedings of the National Academy of Sciences, reveal that may not be the case. Using a combination of theoretical and numerical formulas, astronomers calculated that the planet may actually be able to survive the blast. The difference between life and death depends on that third, distant body. The researchers mathematically showed that the same mechanism that forces the binary together shifts the alignment of the circumbinary planet, potentially allowing it to sneak far enough away to escape incineration. Even so, surviving without a home base is a bit of a lonely swap.last_img read more
