BO Ari Light Curve Analysis using Ground-Based and TESS Data

چکیده
We present new BVR band photometric light curves of BO Aries obtained in 2020 and combined them with the Transiting Exoplanet Survey Satellite (TESS) curves. times minima based on Gaussian Cauchy distributions then applied Monte Carlo Markov Chain (MCMC) method to measure amount uncertainty from our CCD photometry TESS data. A ephemeris binary system was computed employing 204 minimum. The were analyzed using Wilson-Devinney code (MC) simulation. For this curve solution, we considered a dark spot primary component. conclude that is an A-type mass ratio q=0.2074+-0.0001, orbital inclination i=82.18+-0.02 deg, fillout factor f=75.7+-0.8%. Our results for a(Rsun) q parameters are consistent Xu-Dong Zhang Sheng-Bang Qian (2020) model. absolute two components calculated distance estimate found be 142+-9 pc.

متن کاملTechnical Efficiency of Nigerian Insurance Companies: A Data Envelopment Analysis and Latent Growth Curve Modelling Approach
The main purpose of this paper is to investigate the performance of Nigerian insurance companies using Data Envelopment Analysis (DEA). Because of the unavailability of the required data, the study is limited to ten Nigerian insurance companies for the period of five years from 2008 to 2012. The input employed were commission expenses and management expenses, while premium and investment income...
متن کاملAnalyzing Well Production Data Using Combined-Type-Curve and Decline-Curve Analysis Concepts
This paper presents new production decline curves for analyzing well production data from radial and vertically fractured oil and gas wells. These curves have been developed by combining decline-curve and type-curve analysis concepts to result in a practical tool which we feel can more easily estimate the gas ~or oil! in place as well as to estimate reservoir permeability, skin effect, fracture...
