Presentation description

Stellar angular diameter measurements are important for understanding stellar properties, such as effective temperature and stellar radius. One effective method for obtaining these measurements is through asteroid occultations, which create a diffraction pattern when an asteroid passes in front of a star. In this study, we analyzed data from the Very Energetic Radiation Imaging Telescope Array System (VERITAS) during an occultation of the star TYC 2441-1090-1 by the asteroid Severny. By fitting the observed data to a model diffraction pattern, we were able to measure the star's angular diameter. Uncertainties still exist in this measurement, primarily due to the shape of the asteroid, which can cause differences between the diffraction pattern of the ingress and the egress. Future work will be to apply this method of analysis to other occultation events.
