1D accretion discs around eccentric planets: observable near-infrared variability

摘要: I present the results of 1D models circumplanetary discs around planets on eccentric orbits. use a classical viscous heating model to calculate emission fluxes at wavelengths targeted by NIRCam instrument JWST, and compare variability this signal with published sensitivity specifications. This is theoretically detectable JWST for sufficiently disc ($\alpha \sim 10^{-2}$) planet ($e 0.1-0.2$) if accretes material from its parent rate $\dot{M} \gtrsim 10^{-7}\, \mathrm{M}_{\odot}\,\mathrm{yr}^{-1}$. discuss limitations used, implications result probing effectiveness interactions growing planet's orbital eccentricity.
