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?
Testing Einstein’s Equivalence Principle by Timing a Pulsar in a Stellar Triple System
PSR J0337+1715, a millisecond pulsar in a hierarchical stellar triple system with two white dwarfs, provides a stringent test of gravity via Einstein’s strong equivalence principle!
Tiny Stars in a Tiny Orbit: A New Ultracompact Binary
NICER discovers that an accreting millisecond pulsar is actually in a record-setting orbit of 38 minutes with a white dwarf, making it the shortest orbit for this type of X-ray pulsar!
