The Supernova Chirp Reverses on Schedule
Five new modulations in SN 2024afav turned from shortening to lengthening periods at day 147, matching a precessing-disk prediction.
Summary
Five new modulations in SN 2024afav turned from shortening to lengthening periods at day 147, matching a precessing-disk prediction.
A published relation predicted the chirp would halt near day 150 and reverse. Continued follow-up found five modulations whose periods lengthened again, with the turn at day 147 plus or minus three; the interpretation still depends on the proposed disk-and-magnetar model.
Why it matters
Five new modulations in SN 2024afav turned from shortening to lengthening periods at day 147, matching a precessing-disk prediction.
