These waves can reach heights comparable to stacking three suns on top of each other.
The stars in this heartbeat-like stellar system cycle through elongated oval orbits. When the stars swing close together, their gravitational pull causes“The gargantuan waves that roll across the bigger star, kicked up when its smaller companion star regularly makes close passes.
“Most heartbeat stars vary in brightness only by about 0.1%, but MACHO 80.7443.1718 jumped out to astronomers because of its unprecedentedly dramatic brightness swings, up and down by 20%," noted the statement.This model shows how the two stars' interacting gravity causes huge tides in the larger star. These waves can reach heights comparable to stacking three Suns on top of each other.
When the waves crash upon the surface of the huge star, they release enormous amounts of energy. As a result, the star's surface accelerates and hurls outward stellar gas to form a luminous atmosphere surrounding the star. While this star system exudes bizarre traits, it is theorized that such heartbeat systems could be enumerable in the universe. Only around 20 of the approximately 1,000 heartbeat stars found so far show as dramatic fluctuations in brightness as this star system.This study has been published in the journalMassive astrophysical compact halo object 80.7443.1718 is a high mass, eccentric binary system exhibiting the largest-known-amplitude tidally excited oscillations.
