Evaluation of The Fourth-Degree Polynomial Correlation Between Rotational Angular Velocity of Eighty-Four Spiral Barred Galaxies with RadiuS
Abstract
The Spiral-Barred galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in about two-thirds of all spiral galaxies in the local universe. They generally affect the motions of stars and interstellar gas within spiral galaxies and can also affect spiral arms. Python, Visual Studio, and Math Lab are the software used to study eighty-four spiral-barred galaxies. Data for this computation of rotational angular velocity were sourced from the Internet and the National Aeronautics and Space Administration (NASA). These parameter values were used with the equations of rotational angular velocity for estimation. A program was written with Python for the computation of rotational angular velocity, and the results were tabulated alongside data sourced from the Internet with their units. Some of the results for rotational angular velocity generated for eighty-four spiral barred galaxies are Whirlpool/NGC 5194 (4.77E+128 Km/s), Pinwheel/NGC 5457 (4.09E+130 Km/s), Phantom/NGC 628 (1.82E+122 Km/s), Malin I (4.01E+137 Km/s), Messier 98/NGC 4192 (9.57E+128 Km/s), and Messier 109 (6.43E+130 Km/s). It was discovered that the grouped spiral-barred galaxies were atypical of each other since they behaved differently. The 4th-degree galaxies of the same group acted more profoundly in a topsy-turvy manner, since the increased value in the rotational angular velocity increases in the radius and decreases at a certain stage within the radius-increasing range, it picks up again and finally decreases with an increased radius. The 3rd and 4th-degree polynomials of spiral barred galaxies of the same group B act in opposite modus. Eighty–four spiral-barred galaxies were classified into four groups namely: A, B, C, and D, and it was reviewed that all the groups show different characteristics through their plot alignments, which indicates that spiral-barred galaxies are peculiar to each other, which could be as a result of their different angular momentum.
