Tabetha "Tabby" Boyajian is an astronomer and astrophysicist on faculty at Louisiana State University. Boyajian is active in the astronomical fields of stellar interferometry, stellar spectroscopy, exoplanet research, and high angular resolution astronomy, all particularly at optical and infrared wavelengths. She was the lead author of the September 2015 paper "Where's the Flux?", which investigated the highly unusual light curve of KIC 8462852; the star is colloquially known as Tabby's Star in her honor.
Boyajian received a BS degree in Physics with concentration in Astronomy from the College of Charleston in 2003, an MS degree in Physics from Georgia State University in 2005, and a PhD degree in Philosophy of Astronomy from the same university in 2009. She studied the sizes of nearby stars similar to the Sun, using the University's CHARA array, a long-baseline optical and infrared interferometer located at Mount Wilson Observatory. Boyajian was awarded a Hubble Fellowship, and stayed at Georgia State University to study sizes of nearby stars much smaller than the Sun and stars with planets.
It may not host an alien “megastructure” but Tabby’s Star still guards many mysteries of science. Astronomer and astrophysicist Tabetha “Tabby” Boyajian leads the worldwide team that is revealing this strange light in the sky.
