Stellar Evolution Tracks, Isochrones, and Isochrone-Clouds
2021The modelling of stellar interiors is performed by critically comparing observations to carefully constructed theoretical stellar models. These theoretical stellar models are predicated on a number of assumptions and simplifications that have implications for the results of the modelling.

ISOCHRONOUS SECTIONS VIA NORMALIZERS
International Journal of Bifurcation and Chaos, 2005We present some sufficient conditions for the existence of isochronous sections of planar differential systems. We consider isochronous sections at a critical point, a cycle, the boundary of a central or attraction region.

A number of well-known evolution PDEs a remodified so that they then possess many solutions which are isochronous, i.e., completely periodic, with a fixed period that does not depend on the initial data (for large sets of such data).

Summary: In this paper we study a number of nonlinear fractional equations, involving Caputo derivative in space or/and in time, admitting explicit solution in separating variable form. Some of these equations are particularly interesting because they admit completely periodic solutions. When time-fractional derivatives are introduced, this property is

Physics Today, 1964
A new sector-focusing cyclotron, which will accelerate protons over the energy range of 5 to 75 MeV, is being built at the US Naval Research Laboratory. It is expected to produce a circulating beam adjustable from zero to about one milliampere, and an extracted beam several tenths of this amount.
