I will present our recent developments on the equation of state of neutron stars at the upcoming EAS annual meeting

[Nicolas Chamel @NicolasChamel]

I will be presenting two e-posters at the upcoming EAS annual meeting, one about shallow heating in magnetar crusts and the other about gapless superfluidity in accreting neutron stars

[Physical Review X @PhysRevX]

Researchers developed a model that describes the microscopic dynamics of a nucleus accelerating through the #superfluid medium of a #NeutronStar’s inner crust. The #OpenSource tool could be used to shed light on superfluidity in other #nuclear systems.

Uncovering an exotic phase of matter called a supersolid came down to the perfect spin cycle. Researchers used a magnetic field to stir atoms about 50 times a second —fast enough to trigger vortices but gentle enough to preserve the quantum phase.

Back from the 45th International School of Nuclear Physics in Erice, Sicily, Italy, where I gave a lecture on nuclear clustering and pasta in neutron stars. The PDF file can be downloaded here: https://t.co/3KwmkLexrz

Yesterday our @PhysicsColumbia colleague Mal Ruderman passed at 97. He was a great scientist - a legend in the field of neutron star physics - and among the kindest and humblest people I've met. He was active in our department well into his 90s and will be missed.

Le premier magnetar extragalactique découvert par @ESA_Integral dans la galaxie M82 ! Un événement transitoire unique : ces étoiles à neutrons au champ magnétique hyper puissant n’étaient connues que dans notre galaxie.

@martinmbauer Some nuclear clocks are already at our disposal through the extremely stable radio signals coming from neutron stars:

We have found that this peculiar state never considered before can naturally explain the observed late time cooling of neutron stars in low-mass X ray binaries after the end of an accretion episode.

Novel superfluid state of matter discovered in dead stars!

[Nicolas Chamel @NicolasChamel]

Neutron stars can be spun up to very high frequencies by the accretion of matter from a stellar companion. Under such circumstances, we have shown that the neutron superfluid could enter a novel state driven by the pinning of vortices.

[LIGO @LIGO]

We're excited to announce our detection of #GW230529, the first exceptional #GravitationalWaves event from our fourth observing run #O4. Check out @astronerdika’s cool infographic https://t.co/sxd50MyQjU or visit our #GW230529 detection page https://t.co/oGH4baLlss

📢 My Polish colleagues have just released a free software package to probe neutron-star crusts within full 3D time dependent density functional simulations

[ESA Science @esascience]

🆕ESA’s Integral sees, for the first time, how nuclear explosions 💥 on a neutron star feed its jets. Will this help us figure out jets in all sorts of astronomical objects? 🤔

My PhD student Loïc Perot successfully defended his thesis about tidal effects and oscillations of inspiralling compact stars 🥳
