We investigate whether measurements of the neutron star mass and radius or the tidal deformability can provide information about the presence of hyperons inside a neutron star. This is achieved by considering two inference models, with and without hyperons, based on a field-theoretical approach. While current observations do not distinguish between the two scenarios, we have shown that data simulating expected observations from future large area X-ray timing telescopes could provide some information through Bayes factors. Inference using simulated data generated from an EOS containing hyperons decisively favours the hyperonic model over the nucleonic model. However, a 2\% uncertainty in the mass and radius determination may not be sufficient to constrain the parameters of the model when only six neutron star mass-radius measurements are considered.

Neutron stars can shine a light on elusive lepton-flavor-violating dark matter
Flavor blocking keeps lepton-flavor-violating dark matter from thermalizing inside neutron stars, so p-wave annihilation stays efficient and heats the star to observable temperatures.

Dark Matter Heating of Compact Stars Beyond Capture: A Relativistic Framework for Energy Deposition by Particle Beams
A new relativistic formalism computes capture and energy deposition of directed particle beams in compact stars, applied to blazar-boosted dark matter heating of white dwarfs and neutron stars.

A NICER view of the millisecond pulsar PSR J2124$-$3358: evidence for a helium atmosphere
X-PSI modeling of NICER/Chandra data for PSR J2124−3358 substantially prefers a helium atmosphere, giving M = 1.8 ± 0.5 M⊙ and Req = 11.7^{+2.6}_{-3.0} km with two slightly non-antipodal hot spots.
