Can a planet change the measured age of its parent star?
If we know a star’s rotation we can calculate its age. But what happens if this rotation is affected by a nearby massive planet? And how much will this change our age estimate?
Radio Pulsars: How Slow Do They Go?
The discovery of PSR J0250+5854, the slowest radio pulsar, has everyone wondering – how slow does a pulsar need to spin before its radio beam turns off?
