Propiedades métricas de sistemas rotantes relativistas con simetría axial
(2016-05-27)
El presente trabajo caracteriza la naturaleza relativista de las mediciones espacio-temporales sobre sistemas de referencia rotantes con simetría axial. Se introduce una formulación axiomática de los sistemas rotantes ...
The large numbers hypothesis and quantum mechanics
(1998)
In this paper, the suggested similarity between micro and macrocosmos is extended to quantum behavior, postulating that quantum mechanics, like general relativity and classical electrodynamics, is invariant under discrete ...
Evidence for disc regulation in the lowest mass stars of the young stellar cluster NGC 2264
(Oxford University Press, 2019-08)
In the pre-main-sequence stage, star-disc interactions have been shown to remove stellar angular momentum and regulate the rotation periods of stars with M2 and earlier spectral types. Whether disc regulation also extends ...
Are you experienced? Contributions towards experience recognition, cognition, and decision making
(2016-12-08)
Este trabalho consiste em três contribuições independentes do âmbito da modelagem cognitiva ao campo de management science. O primeiro aborda Experience Recognition, uma teoria inicialmente introduzida por Linhares e Freitas ...
VLTI/PIONIER images the Achernar disk swell
(EDP Sciences, 2017-05)
Context. The mechanism of disk formation around fast-rotating Be stars is not well understood. In particular, it is not clear which mechanisms operate, in addition to fast rotation, to produce the observed variable ejection ...
A catalog of rotational and radial velocities for evolved stars - IV. Metal-poor stars
(EDP SCIENCES S A, 2006-11)
Aims. The present paper describes the first results of an observational program intended to refine and extend the existing v sin i measurements of metal-poor stars, with an emphasis on field evolved stars.
Methods. The ...
