Ongoing celestial processes are at work across the universe, some of which are beyond the scope of human imagination and scientific comprehension. As scientific research moves forward, novel methodologies emerge, and findings that were previously hidden are brought to light. We are now able to detect whether or not there are planets circling around dead binary stars thanks to the research that was conducted at a university in Mexico. The primary author of this research is Dr. Carlos Chavez, who is affiliated with the Universidad Autónoma de Nuevo León in the country of Mexico.
The Cataclysmic Variables (CVs) were the subject of this study. Cataclysmic Variables are a sort of binary system in which the two stars are so close to each other that the larger star drains material from the smaller star while the two stars spin around each other. When it comes to CVs, the larger star, known as the primary, is almost always a white dwarf, while the smaller star, known as the donor, is almost always a red dwarf. The material for the primary star comes from the donor star.
As the material is pulled in, it produces what is known as an accretion disc, which is a hot disc that orbits the star. There is a point in such a binary star system where gravitational equilibrium can be attained. This location is known as the Lagrangian Point.
Oscillations in the position of the Lagrangian Point are brought about by the presence of a planet in a stellar system. Because of this, there are subsequent shifts in the overall luminosity of the star system. According to the findings of certain researchers, it is possible to ascertain whether or not a planet is there by monitoring changes in the luminosity of the target.
