Context. Classical novae are powered by thermonuclear runaways occurring on the surface of accreting white dwarfs (WDs). In observations, enrichments heavy elements in nova ejecta have been detected, indicating a mixing process between accreted matter and from outer layers underlying WDs prior to outbursts. However, fraction classical is still uncertain. Aims. The purpose this article investiga...

Many mathematicians have investigated the properties of continued fractions. They made fraction expansions Pi number, golden ratio and many more special numbers. With help fractions, solutions some Diophantine equations are obtained. In this study, encryption was using fractional square root non-perfect-square integers. Each 29 letters in alphabet is represented by nonperfect integers starting ...

Abstract By using a jump transformation associated to the Romik map, we define new continued fraction algorithm called odd-odd fraction, whose principal convergents are rational numbers of odd denominators and numerators. Among others, it is proved that all best approximating rationals numerators an irrational number given by vice versa.
