Modelling Binary Orbits in the WIYN Open Cluster Survey - The alternative evolutionary tracks for binary stars.
Date:
Abstract: We utilized theJoker sampler, initially created for APOGEE’s sparsely and noisily measured radial velocities, in our examination of the WIYN Open Cluster Survey. After utilizing rejection and MCMC sampling with theJoker, we scrutinized single-lined binaries orbits in M67 and NGC 188. Our objective was to evaluate theJoker’s efficacy on binaries with ample radial velocity data (RVD) and investigate the possibility of devising observing plans that would enable us to estimate binary orbital solutions with fewer RVD and better understand the alternative evolutionary tracks for binary stars.
