The cosmic DANCe of Perseus I: Membership, phase-space structure, mass, and energy distributions
J. Olivares, H. Bouy, N. Miret-Roig +4
Context. Star-forming regions are excellent benchmarks for testing and validating theories of star formation and stellar evolution. The Perseus star-forming region being one of the…
Exact solutions and conservation lawsof a one-dimensional PDE model for a blood vessel
Stephen C. Anco, Almudena P. Marquez, Tamara M. Garrido +1
Two aspects of a widely used 1D model of blood flow in a single blood vessel are studied by symmetry analysis, where the variables in the model are the blood pressure and the cross…
Symmetry analysis and hidden variational structure of Westervelt's equation in nonlinear acoustics
Stephen C. Anco, Almudena P. Marquez, Tamara M. Garrido +1
Westervelt's equation is a nonlinear wave equation that is widely used to model the propagation of sound waves in a compressible medium, with one important application being ultra-…
Conservative algebras of -dimensional algebras, IV
Amir Fernández Ouaridi, Ivan Kaygorodov, Cándido Martín González
The notion of conservative algebras appeared in a paper by Kantor in 1972. Later, he defined the conservative algebra of all algebras (i.e. bilinear maps) on the -dimensi…
Ultracool dwarfs in Gaia DR3
L. M. Sarro, A. Berihuete, R. L. Smart +36
Aims. In this work we use the Gaia DR3 set of ultracool dwarf candidates and complement the Gaia spectrophotometry with additional photometry in order to characterise its global pr…
Conservation laws, symmetries, and line solitons of a Kawahara-KP equation
Almudena P. Marquez, Maria L. Gandarias, Stephen C. Anco
A generalization of the KP equation involving higher-order dispersion is studied. This equation appears in several physical applications. As new results, the Lie point symmetries a…
