We present a framework for estimating exoplanet occurrence rates by synthesizing constraints from radial velocity and transit surveys simultaneously. employ approximate Bayesian computation various mass-radius (M-R) relations to explore the population models describing these surveys, both separately in joint fit. Using this approach, we fit planet distribution function of form $d^{2} N/d\log{P}...

In this paper we present RELXILLDGRAD_NK, a relativistic reflection model in which the electron density of accretion disk is allowed to have radial power-law profile. The ionization parameter has also non-constant profile and calculated self-consistently from emissivity. We show impact implementation gradient our by analyzing NuSTAR spectrum Galactic black hole EXO 1846-031 during its last outb...
