Heartbeat stars are double stars that appear as special variable stars. One of them has the dramatic light variations that now result from giant waves of plasma colliding on the surface of a star, such as giant tidal waves. interstellar,

we owe newtonnewton The first scientific and quantitative theory of tides on Earth. This theory was developed by Laplace (French Newton because of his contributions to mathematics and astronomy according to the British) in his treatise on celestial mechanics, and later by Poincaré. during the XXI century, the theory of tides was transferred to both the other planets of the Solar System and StarsStarsWhich is hardly surprising because it is not without reason that we talk about this principle GravityGravity universal.
Thus we know that it is tidal forces that are responsible for the monstrous volcanism of Io, which is one of the main mondaymonday Of JupiterJupiter, most stars GalaxyGalaxyand no doubt others GalaxiesGalaxiesCreature binary systembinary system (see triplets and even sextuples), one might expect that significant tidal forces would be exerted on each member star of such a system when they are particularly close to each other, sometimes to the point of rupture. till.

stars warped by tidal forces
Many such double stars have been observed, and observations by the Kepler satellite have shown that many such stars are called heartbeat stars. From Kepler’s point of view, we see that the curve of lightslights The number of these stars does not change only from time to time variable starsvariable stars Pulsed Magazines.
the shape of the light curve is reminiscent of a electrocardiogramelectrocardiogram and we came to understand that part of the pulsations observed were due to the fact that one of the stars is on To revolve aroundTo revolve around Quite elliptical around each other, causing it to approach quite close to its companion star (heartbeat stars can only approach within a few stellar radii of each other). just as the oceans on earth take on a form balloonsballoons Rugby’s, an ellipsoid of rotation under the action of tidal forces, the surfaces of the two stars do the same and as they are in motion we see them alternate according to the orientation of the brightest part due to the distortion surfaces Two stars that follow the motion of one around the other.

two today astronomyastronomy Americans have come to the conclusion that this phenomenon is taking a dreadful form as well as taking a dreadful form. Wave’sWave’s Tides on the surface of one of the stars of the Macho binary system 80.7443.1718. As its name suggests, it was discovered during the 1990s during a research campaign based on the theory of gravitational micro-lensing. it was about macho hunting massive astrophysical dense halo object) imaginary dense and dark colored objects, such as brown dwarfbrown dwarf or primordial black holes, which may spin in the halo of a galaxy and cause its nature dark matterdark matter, When passing in front of a star, Macho was supposed to make it brighter for a moment with the lens effect.
4.3 million km high tidal waves occur every month
In the case of Macho 80.7443.1718, the origin of the peak GlowGlow As explained in a press release from the Center for Astrophysics-Harvard & Smithsonian (CFA) in the United States, the initially observed result was quite different. The close passage of the smaller star causes the rise of the larger star, which consists of about 35 stars. publicpublic Solar, tidal waves that have nothing to envy to those on Miller’s planet interstellar,

No wonder that upon its discovery, the binary puzzled astrophysicists. The luminosity of heartbeat stars typically varies by only 0.1%, whereas in the case of Mach 80.7443.1718, it is about 20%, a number never seen before.
The crash of a giant breaker on the surface of the main star occurs every month and according to numerical simulations this creates an ejection of material over the star that feeds an atmospheric shell that begins to glow in a characteristic way, giving a signature Get. giant breaker event
A Harvard press release noted that in fact the case of Macho 80.7443.1718 should not be unique as it has recently been understood that of the approximately 1,000 heartbeat stars discovered so far, only about twenty have large luminosities close to the system. Ups and downs do exist. Simulated by MacLeod and Loeb.
