Title: A Five-Fold Increase In "Holy Grail'" Calibrators For Stellar Models: Doubly-Oscillating Binaries Pre-Screened With Gaia

PI: Joyce, Meridith - University Of Wyoming

Type: SMALL

Summary: We propose to obtain a mix of 20-s cadence and 200-s FFIs for 972 binary systems likely to host detectable oscillations in both components, selected with Gaia. We will combine asteroseismic parameters nu max and delta nu extracted from these images with luminosities, distances, and temperatures to obtain asteroseismic masses. Combined with metallicities obtained from gaia-xgboost and spectroscopic follow-up, these masses complete the set of constraints needed to calibrate isochrones. Such calibration systems are rare: this campaign will yield a 5-fold increase in the number of ``holy grail'' targets whose components share an age but have two different masses. We will use Cycle 7 s timely overlap with K2 fields to benchmark our method for 20 targets observed in both K2 and TESS Cycle 7.
