# TESS Program G03204

Title: Investigating Temporal Variations In The Bright Rrc Stars

PI: Wilhelm, Ronald - University Of Kentucky

Type: SMALL

Summary: Our Cycle 3 TESS GI proposal is to observe and analyze a sample of 31 bright, non-Blazhko, first-overtone (RRc), RR Lyrae variables with the 2-minute cadence program. Our goal is to investigate temporal variability in the primary radial pulsation mode, fo, and the well known non-radial pulsation mode, fx, found in most RRc stars (fo/fx ~ 0.61). For stars with the fx mode, we will also explore variability in any identifiable half-integer, sub-harmonic frequencies. Our ultimate goal is to compare the short-term and long-term variability in order to constrain the period-shifting effect seen in many RRc stars. We will also use the subset of our sample which has published kinematic observations to help constrain the physical properties that produce this non-radial mode.
