Every star has its own unique spectra based on the star’s composition. As a planet orbits a star it causes the star to “wobble” from its gravitational force, causing a blueshift or redshift in the stellar spectra. However, the star’s magnetic field causes disturbances that can mask or mimic the signals produced by the planet. This can often lead to an exoplanet being falsely confirmed. This poster will focus on the red dwarf GJ 625, where a confirmed exoplanet was discovered orbiting the star. Using the NWelch software produced by Dr. Sarah Dodson-Robinson, an analysis was conducted to further validate the detection.
