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…
Observatory Science with eXTP
Ping Zhou, Jirong Mao, Liang Zhang +97
Scheduled for launch in 2030, the enhanced X-ray Timing and Polarization (eXTP) telescope is a Chinese space-based mission aimed at studying extreme conditions and phenomena in ast…
3D Simulations of Convective Entrainment in Gas Giants: Rotation and Decreasing Luminosity as Barriers to Mixing
Shu Zhang, J. R. Fuentes, Andrew Cumming
Observations from Juno and Cassini suggest that Jupiter and Saturn may possess fuzzy cores -- central regions where the abundance of heavy elements varies smoothly with depth. Such…
Weak Bursts on Slowly Accreting Neutron Stars
Sierra Casten, Simon Guichandut, Andrew Cumming +1
Nearly all observed thermonuclear X-ray bursts are thought to be triggered by the thermally unstable triple-alpha process. Unlike in accreting white dwarfs, the $\gtrsim10^{8} \mat…
