Supernova remnants in clumpy medium: A model of hydrodynamic and radio synchrotron evolution

Autor: Kostić, Petar, Arbutina, Bojan, Vukotić, Branislav, Urošević, Dejan

We present an analytical model of $\Sigma-D$ relation for supernova remnants (SNRs) evolving in a clumpy medium. The model and its approximations were developed using the hydrodynamic simulations of SNRs in environments of low-density bubbles and clu

Photometric and Spectroscopic study of Ten Low Mass Ratio Contact Binary Systems: Orbital Stability, O'Connell Effect and Infra-red Calcium Line Filling

Autor: Wadhwa, Surjit S., Popowicz, Adam, Michel, Raul, Kostic, Petar, Vince, Oliver, Tothill, Nick F. H., De Horta, Ain Y., Filipovic, Miroslav D.

Low mass ratio contact binary systems are more likely to have unstable orbits and potentially merge. In addition, such systems exhibit characteristics such as starspots and high energy emissions (UV) suggestive of chromospheric and magnetic activity.

Effects of Metallicity on the Instability Mass Ratio of Low Mass Contact Binary Systems

Autor: Wadhwa, Surjit S., Landin, Natalia R., Kostic, Petar, Vince, Oliver, Arbutina, Bojan, De Horta, Ain Y., Filipovic, Miroslav D., Tothill, Nicholas F. H., Petrovic, Jelena, Djuravsevic, Gojko

The orbital stability of contact binary systems has been receiving considerable attention recently. Theoretical studies indicate that merger is likely to occur at very low mass ratios, but the actual mass ratio at which merger may take place is likel

There are many benefits in providing formal specifications for our software. However, teaching students to do this is not always easy as courses on formal methods are often experienced as dry by students. This paper presents a game called FormalZ tha

Interstellar medium structure and the slope of the radio $\Sigma-D$ relation of supernova remnants

Autor: Kostić, Petar, Vukotić, Branislav, Urošević, Dejan, Arbutina, Bojan, Prodanović, Tijana

We analyze the influence of fractal structure of the interstellar matter (ISM) density on the parameter values for the radio surface brightness to diameter ($\Sigma-D$) relation for supernovae remnants (SNRs). We model a dense ISM as a molecular clou
