Binary star systems have long fascinated astronomers with their variable brightness caused by the orbital motion of the stars. At times, the stars may appear as a single point of light due to their close proximity. Among these fascinating systems, a particular group called heartbeat stars has recently captivated the scientific community.
Heartbeat stars have highly eccentric orbits that distort them into egg shapes when they pass close to each other. This distortion results in a spike in brightness, resembling a heartbeat seen on an electrocardiogram. However, the latest discovery of MACHO 80.7443.1718, published in Nature Astronomy, has left astronomers in awe.
What sets MACHO 80.7443.1718 apart from other heartbeat stars is its peak brightness, which is a staggering 200 times greater than typical heartbeat stars. This newly discovered binary system is composed of a primary star with a mass equivalent to 35 Suns and a secondary star weighing 16 solar masses. Remarkably, the stars orbit each other every 33 days, making their closest approach even closer than the distance between Mercury and the Sun.
During these close encounters, the stars experience intense tidal forces, contributing to their significant brightening. Unlike other heartbeat stars, MACHO 80.7443.1718 displays a slow dimming and oscillating decay in its light curve. To understand these unique features, computer models were utilized to investigate the stars’ behavior during close approach.
The models revealed that the smaller companion star captures atmospheric material from the larger star, triggering oscillations in the primary star. As the primary star rotates on its axis, waves form on its surface under the influence of the companion star’s gravitational pull. These waves propagate along the surface, causing the wobbling decay observed in the light curve of MACHO 80.7443.1718.
This groundbreaking discovery underscores the complexity of binary star interactions and their influence on stellar evolution. The findings are shedding new light on the mechanisms behind heartbeat stars and expanding our understanding of stellar dynamics.
The study, entitled “Breaking waves on the surface of the heartbeat star MACHO 80.7443.1718,” was published in the esteemed journal Nature Astronomy. Scientists hope that further research will unlock more secrets of these mesmerizing celestial systems, bringing us closer to unraveling the mysteries of the universe.
As astronomers continue to explore the cosmos, captivating discoveries like that of MACHO 80.7443.1718 remind us of the wonders that await us beyond our planet and the constant evolution of our understanding of the cosmos.
