Asteroseismic Detection of a Massive Unseen Companion to the delta Scuti Star TIC 160582982
Asteroseismic analysis of TIC 160582982, a delta Scuti binary, used high-frequency pressure modes as pulsation clocks to detect a massive unseen companion. Orbital constraints suggest a minimum companion mass around 1.80 M⊙, strongly disfavoring an ordinary main-sequence star and pointing toward a compact remnant like a neutron star or black hole.
