[astro-ph.SR] Detecting planetary companions around evolved stars, particularly asymptotic giant branch (AGB) stars, is challenging due to intrinsic stellar variability such as surface convection, pulsations, and mass loss, which can […]
![Assuming the presence of two companions, the orbital evolution of the HD 216595 system for 500 years from the best-fit orbit: (a) orbits of the system, (b) the evolution of the semi-major axes, and (c) the evolution of the eccentricities. Blue color indicates the inner companion and black color is the outer companion. -- [astro-ph.SR]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/A-Search-for.png?resize=1200%2C652&ssl=1)
