A Search for Transiting Doppler-Detected Exoplanets

There have been indefatigable pursuits of exoplanets and their host stars, spanning from the first ever discovery of exoplanets in 1992 to today. Many researchers have analysed data in hope of detecting new planets, or to obtain more information regarding the host stars. Here, we present a search for transits of exoplanets in samples of stars with the following criteria: near Earth - within 50 parsecs, and has a planet/planets confirmed via methods other than the transit method. Using recent data from NASA's Transiting Exoplanet Survey Satellite (TESS), we were able to conduct analysis on data of a star in different time intervals, resulting in a more thorough investigation as for the presence of transits. We found possible transit times using Python algorithms integrating the times of conjunction and period of the planet for potential candidate GJ 1061, which has a perfect low noise curve but does not demonstrate transits. The algorithm is also used in confirming visible transits for star L98-59, turning out to be its three known transiting planets. We also analysed light curves of the star HS Psc, which is sinusoidal and points to the possibility of a rotating pulsator. Most importantly, we found a possibly undiscovered eclipsing binary with approximately the same line of sight to star HD 187123.
