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?
Thats no exomoon… or is it? A careful evaluation of evidence for Kepler-1625b-i
Moons of exoplanets have not yet been conclusively. Today’s authors carefully re-evaluate some of the evidence for their own candidate detection of the first known exomoon.
Cepheid yourself – confirming tensions in the Hubble expansion
New observations of pulsing variable stars weigh in on the Hubble tension. Find out how in this Astrobite!
A Strange Type of Matter May Lie at the Heart of Neutron Stars
A mysterious type of matter, quark-gluon plasma, may lie at the heart of neutron stars.
Looks like the Sun, but does it spin like the Sun: measuring differential rotation in 16 Cyg A & B
The Sun is known to rotate differentially, which plays a large part in our understanding of solar physics. Do we see the same differential rotation in Solar analogues, 16 Cyg A & B?
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!
