A nearly cylindrically symmetric source in the Brans-Dicke gravity as the generator of the rotational curves of the galaxies

S. Mittmann dos Santos, J. M. Hoff da Silva, M. E. X. Guimarães +1

Observation shows that the velocities of stars grow by approximately 2 to 3 orders of magnitude when the distances from the centers of the galaxies are in the range of kpc to…

Decay Estimates for Solutions of Porous Medium Equations with Advection

Nicolau Matiel Lunardi Diehl, Lucineia Fabris, Juliana Sartori Ziebell

In this paper, we show that bounded weak solutions of the Cauchy problem for general degenerate parabolic equations of the form \begin{equation} \notag u_t \,+\; \mbox{div}\,f(x,t,…

Straight spinning cosmic strings in Brans-Dicke gravity

S. Mittmann dos Santos, J. M. Hoff da Silva, J. L. Cindra

It is presented an exact solution of straight spinning cosmic strings in Brans-Dicke theory of gravitation. The possibility of the existence of closed timelike curves around these…

Weyl frames and canonical transformations in geometrical scalar-tensor theories of gravity

A. B. Barreto, M. L. Pucheu, C. Romero

We consider scalar-tensor theories of gravity defined in Weyl integrable space-time and show that in the ADM formalism Weyl transformations corresponding to change of frames induce…

Low mass variable stars in the globular cluster NGC 6397

E. Martinazzi, S. O. Kepler, J. E. S. Costa

We have conducted a photometric survey of the globular cluster NGC 6397 in a search for variable stars. We obtained ~11h of time-resolved photometric images with one ne European So…
