# TESS Program G03132 Title: Asteroseismology Of Tic 350146296: The Shortest Period Rapidly Oscillating Ap Star With A Rich Pulsation Spectrum PI: Holdsworth, Daniel - University Of Central Lancashire Type: SMALL Summary: TIC 350146296 was discovered to be a member of the rare class of rapidly oscillating Ap stars through TESS observations. To date, it exhibits the highest pulsation frequencies of any of the roAp stars. These are above the theoretical limit expected in roAp stars, making this star a key for constraining non-adiabatic pulsation models of Ap stars. However, amplitudes in the current TESS data are suppressed by as much as 27%, caused by apodization, thus hampering the detection of further, low-amplitude modes that are required for a full asteroseismic model. We propose to observe TIC 350146296 in the newly available 20-sec cadence mode for the duration of cycle 3 as this star is in the CVZ. This is a prime example of how the shortest cadence observations will maximise TESS science results. # Sector 027 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 028 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 029 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 030 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 031 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 032 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 033 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 034 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 035 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 036 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 037 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 038 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET # Sector 039 targets observed (2 min: 1, 20 s: 1) 350146296,115.7396,-63.7019,9.17,G03132;G03255;G03252;20SECONDTARGET
