"Enormous Plasma Waves Emanate from Massive Star, Potentially Causing Gigantic Tidal Phenomena"

Astronomers have used computer simulations to study the massive tides on the star MACHO 80.7443.1718, which create plasma waves 2 million miles high, three times larger than the Sun. These waves are caused by the gravitational forces between the star and its smaller companion, resulting in extreme tides that rise and fall in a regular rhythm. The breaking of these plasma waves affects the star's rotation and orbit, with each wave releasing a significant amount of energy. This discovery suggests that MACHO 80.7443.1718 is just the first of a new class of objects with extreme plasma tidal waves.

"Colossal Star's Turbulent Convection Unleashes Monster Waves"

Researchers have discovered a star system, known as a "heartbeat star," where massive tidal waves generated by the gravitational interaction between two stars crash onto the surface of the larger star. These waves, as tall as three suns stacked on top of each other, cause dramatic brightness fluctuations in the system. Dubbed a "heartbreak star," this phenomenon provides a unique opportunity to study the interaction of massive stars and gain insights into stellar evolution. The discovery suggests that there may be more similar objects in the universe, and astronomers are planning to search for more "heartbreak stars" to further investigate this phenomenon.
