It can either be abstract concepts or concepts applied to other disciplines, such as Physics, Engineering, and Computer science. In physics, mathematics has been described as "an essential tool", used to prove theories and justify hypotheses made by physicists. Mathematics can also be defined as a natural numerical analysis, whereas the product that we obtain from those analyses is called engineering (from mechanical to industrial.)<br />Different subfields in mathematics, such as Logic and Linear algebra, can also be recognized as the foundation of other fields, such as computer science. Computer science can be described as the study of computers and computational systems, and it sometimes can even be viewed as a mathematical science due to its close relationship with mathematics.</p> </div> Hyperjournal en-US Hyperscience International Journal 2821-3300 https://hscience.org/index.php/hij/article/view/24 <p>HD 158259 (or HIP 85268) is one of the members of the main sequence in G0 group stars located approximately at 88 ‎light-years away in the constellation Draco, discussed with respect to the solar system. HD 158259 was discovered by the ‎SOPHIE échelle spectrograph using the radial velocity method. This system includes five confirmed planets orbiting HD ‎‎158259, together with one unconfirmed planet. The planets orbit in a near 2/3 (or 3:2) orbital resonance. Starting from the innermost pairing, the period ratios are with the period ratios ‎‎1.5757, 1.5146, 1.5296, 1.5128, and 1.4482, respectively, starting from the innermost pairing. Here we theoretically investigate the HD ‎‎158259 system for the Semi-major axis, planet's mass, star luminosity, ‎ inner,‎ ‏ ‏center, outer, and ∆(HZ) habitable zone. We account for radial ‎velocity amplitude, planet density, and Laplace’s resonance, theoretically. The existing possibility of the sixth and undetected ‎planet (HD 158259 g) was also investigated. The orbital period and semi-major axis of this planet, computed with 0.047726 years (17.420 ‎days) and 0.135 AU respectively, with ????² = 0.9964. The radial velocity amplitude of this new and undetected planet was ‎computed to be about 1.625 km/s. The mass of planets in terms of Solar, Jupiter, and Earth have shown direct direct proportional ‎relation with an approximate<br>increase in their semi-major axis. The lowest mass is closest to the star and the highest mass is farthest from the star. We compare<br>the habitability zone to that of NASA, Kopparapu et.al, and the original Kopparapu estimate. The application of the relative<br>mean motion ration (RMMR) for resonance in the triads of successive planets showed that the mode of RMMR is approximately<br>2/3 (or 3:2) orbital resonance, with the calculated period ratios shown above. we have also calculated the planetary equilibrium temperature (PET) in terms of the size, temperature, Albedo and distance planet to its parent star.</p> Rezvan Saleh Ghafari Bijan Nikouravan * M.K.
