On the impact of the carbon fusion rate over the properties of superbursts -- Numerical simulations of superbursts with MESA
Martin Nava-Callejas, Stéphane Goriely, Nicolas Chamel
Context: Superbursts are very energetic explosions in the crust of neutron stars in Low-Mass X-ray Binaries (LMXBs). These are triggered by unstable carbon burning at $T\leq 10^{9}…
On a re-examination of neutron star cooling in transient sources -- No shallow heating required?
Martin Nava-Callejas, Yuri Cavecchi, Dany Page
Context: For the typical modeling of neutron stars cooling after an accretion episode in Low-Mass X-ray Binaries, an extra heating source of unknown physical origin, \textit{the sh…
A solution to the tension of burning on neutron stars and nuclear physics
Y. Cavecchi, D. Galloway, A. Heger +8
When neutron stars accrete matter from a companion star, this matter forms a disc around them and eventually falls on their surface. Here, the fuel can ignite into bright flashes c…
Post-Supernova Accretion of Light Elements onto a New-Born Neutron Star and NS 1987A
Natalia de Jesús Baz-Pérez, Dany Page, Simon Guichandut +3
We model early accretion of light elements, He, C, and O, onto a new-born neutron star using the public stellar evolution code MESA, simulating what may happen during the first few…
Thermonuclear Heating of Accreting Neutron Stars
Martin Nava-Callejas, Dany Page, Yuri Cavecchi
We describe a new method to incorporate thermonuclear heating in the envelope of accreting neutron star into long term simulations of their thermal evolution. We obtain boundary co…
