Evolving supernova remnants in multiphase interstellar media [PDF]
, 2019 We performed three-dimensional magnetohydrodynamic simulations to study the evolution of a supernova remnant (SNR) in a turbulent neutral atomic interstellar medium. The media used as background shares characteristics with the Solar neighbourhood and the

Thin shells surrounding black holes in F(R) gravity [PDF]
, 2019 In this article, we consider spherical thin shells of matter surrounding black holes in F(R) theories of gravity. We study the stability of the static configurations under perturbations that conserve the symmetry.

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 ...

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 ...
