Bayesian analysis of exoplanet and binary orbits

TL;DR

This paper presents BASE, a new Bayesian analysis tool for exoplanet and binary star orbit characterization, demonstrated on Mizar A data, enabling combined or separate analysis of astrometric and spectroscopic measurements.

Contribution

The paper introduces BASE, a novel software that integrates Bayesian methods for analyzing astrometric and spectroscopic data of exoplanets and binaries, improving orbit detection and characterization.

Findings

Successfully analyzed Mizar A data with BASE

Demonstrated combined astrometric and spectroscopic analysis capabilities

Enhanced orbit parameter estimation accuracy

Abstract

We introduce BASE (Bayesian astrometric and spectroscopic exoplanet detection and characterisation tool), a novel program for the combined or separate Bayesian analysis of astrometric and radial-velocity measurements of potential exoplanet hosts and binary stars. The capabilities of BASE are demonstrated using all publicly available data of the binary Mizar A.
