Shadow cast by rotating braneworld black holes with a cosmological constant [PDF]
, 2018 In this article, we study the shadow produced by rotating black holes with a tidal charge in a Randall-Sundrum braneworld model, with a cosmological constant.

Ensino de astronomia: uma abordagem didática a partir da Teoria da Relatividade Geral
Revista Brasileira de Ensino de Física, 2021 A partir da análise de uma articulação entre as perspectivas cognitivistas da aprendizagem significativa de David Ausubel e educacionais das comunidades de investigação presentes no programa de filosofia de Matthew Lipman, este artigo discute o ...

Ross 128-GL 447: A possible activity cycle for a slow-rotating fully convective star [PDF]
, 2019 Context. Long-term chromospheric activity in slow-rotating fully convective stars has scarcely been explored. Ross 128 (Gl 447) is a slow-rotator and inactive dM4 star that has been extensively observed.

Enhanced transport through desorption-mediated diffusion [PDF]
, 2013 We present a master equation approach to the study of the bulk-mediated surface diffusion mechanism in a three-dimensional confined domain. The proposed scheme allowed us to evaluate analytically a number of magnitudes that were used to characterize the ...

Two successive partial mini-filament confined ejections [PDF]
, 2019 Active region (AR) NOAA 11476 produced a series of confined plasma ejections, mostly accompanied by flares of X-ray class M, from 08 to 10 May 2012. The structure and evolution of the confined ejections resemble that of EUV surges; however, their origin ...

Are CMEs capable of producing Moreton waves? A case study: The 2006 December 6 event [PDF]
, 2018 Considering the chromosphere and a stratified corona, we examine, by performing 2D compressible magnetohydrodynamics simulations, the capability of a coronal mass ejection (CME) scenario to drive a Moreton wave. We find that given a typical flux rope (FR)

Blue lines as chromospheric diagnostics: The Si I lines at 3906 and 4103 Å [PDF]
, 2001 We present a complete atomic model for Si I line synthesis. We study how the computed profiles of two blue lines of this atom are influenced by the choice of the atomic parameters and find that, although several cross sections are not known accurately ...
