Title: Exoplanet And Binary Demographics Around The A-Type Stars Using Pulsation Timing

PI: Hey, Daniel - University Of Hawaii (Manoa)

Type: SMALL

Summary: Stellar companions and exoplanets in wide orbits are poorly understood, in particular around intermediate-mass stars for which spectroscopic radial velocities cannot be precisely measured. We propose to use pulsation timing variations to map orbits around the intermediate-mass delta Scuti variable stars, probing both exoplanets and binary companions. The method is immune to data gaps and increases in sensitivity with the orbital period and is thus ideally suited for the 7-year timebase that will be enabled through TESS Cycle 7.
