Remarks on Chebyshev representation of ephemeris
Yanning Fu
Chebyshev coefficients of a coordinate representation can be used to form the corresponding velocity representation. One way is to directly apply them to the derivatives of Chebysh…
A first-order dynamical model of hierarchical triple stars and its application
Xingbo Xu, Fang Xia, Yanning Fu
For most hierarchical triple stars, the classical double two-body model of zeroth-order cannot describe the motions of the components under the current observational accuracy. In t…
Some remarks about Descartes' rule of signs
Alain Albouy, Yanning Fu
What can we deduce about the roots of a real polynomial in one variable by simply considering the signs of its coefficients? On one hand, we give a complete answer concerning the p…
Mass Segregation of Embedded Clusters in the Milky Way
Xinyue Er, Zhibo Jiang, Yanning Fu
Embedded clusters are ideal laboratories to understand the early phase of the dynamical evolution of clusters as well as the massive star formation. An interesting observational ph…
Relative equilibria of four identical satellites
Alain Albouy, Yanning Fu
We consider the Newtonian 5-body problem in the plane, where 4 bodies have the same mass m, which is small compared to the mass M of the remaining body. We consider the (normalized…
The Empirical Mass-Luminosity Relation for Low Mass Stars
Fang Xia, Shulin Ren, Yanning Fu
This work is devoted to improving empirical mass-luminosity relations and mass-metallicity-luminosity relation for low mass stars. For these stars, observational data in the mass-l…
