How can we be sure that when looking for planets there sun is not a perfect sphere and just looks like it is being perturbed by a gravitating body?

The main objective of detecting unusual stellar shapes is to identify potential exoplanets in orbit around a star. By studying the shape of a star, scientists can determine if it is being gravitationally pulled or distorted by a nearby planet.
Scientists use a technique called photometric variability to detect unusual stellar shapes. This involves measuring the changes in a star's brightness over time. If a star's brightness varies in a regular pattern, it could indicate the presence of a planet.
Detecting perturbed planets is important because it can give us valuable information about the formation and evolution of planetary systems. It can also help us to better understand the diversity of planets in our galaxy and the potential for habitable worlds.
One of the main challenges in detecting unusual stellar shapes is differentiating between natural variations in a star's brightness and the effects of a nearby planet. This requires careful data analysis and confirmation from multiple observations.
The detection of unusual stellar shapes can contribute to the search for extraterrestrial life by identifying potential exoplanets that may have the conditions necessary for life to exist. This information can then be used to prioritize future studies and observations of these planets.
