PSR J2322-2650b Archives

The companion light curve in two continuum bands interpreted with a pulsar direct heating model. (a) The models are shown by the curves and the data are shown by the points. The model does not capture the strong orbit-to-orbit variations at minimum (ϕ ∼ 0 and ϕ ∼ 1), but provides a good description of the flux from the heated face and constrains the binary parameters (see Appendix 5). Schematics of the Earth-view of the heated companion’s surface temperature are shown below the light curve. (b),(c) The residuals of the models compared to their corresponding light curves. astro-ph.EP

A Carbon-rich Atmosphere On A Windy Pulsar Planet

by Keith CowingSeptember 15, 2025September 14, 2025

A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum density of 1.8 g/cm^3 […]
