# TESS Program G022157 Title: TESS Observations Of The Bright Cepheid Polaris PI: Buzasi, Derek - Florida Gulf Coast University Type: SMALL Summary: Polaris, the current North Pole Star, is the brightest Cepheid in the sky, and features a dominant pulsation period of approximately 3.974 days. As the prototypical Classical Cepheid, the star has served as a laboratory for studies of the period-luminosity relationship, stellar pulsation, and massive star evolution for more than a century. Ironically, despite this concentrated study - and over 750 ADS publications - much remains uncertain about this valuable astrophysical laboratory, including its mass, radius, age, and evolutionary state. TESS provides a unique and crucial opportunity to clarify this confusing situation and to test the stability of Polaris' light amplitude as well as the presence of additional short-timescale variability previously reported for the star. # Sector 019 targets observed (1) 303256075,37.9672,89.2641,1.37,G022157;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 # Sector 020 targets observed (1) 303256075,37.9672,89.2641,1.37,G022157;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 # Sector 025 targets observed (1) 303256075,37.9672,89.2641,1.37,G022157;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25 # Sector 026 targets observed (1) 303256075,37.9672,89.2641,1.37,G022157;G022133;G_NONSTANDARDMASK;G_NOPHOTOMETRY;G_SPECIAL_APERTURE_25_25
