KIC 9272276: An Extreme Low Mass Ratio Red Nova Progenitor
Surjit Wadhwa, Marko Grozdanovic, Bojan Arbutina +2
Photometric analysis of KIC 9272276 (K9272), a low-mass contact binary system, is presented. We find it to be an example of an extreme low mass ratio system that satisfies the curr…
Study of a giant Large Magellanic Cloud Supernova Remnant, Veliki (J0450.4-7050)
Z. J. Smeaton, M. D. FilipoviÄ, R. Z. E. Alsaberi +12
We present a high-resolution radio-continuum view and a multi-frequency analysis of the Large Magellanic Cloud (LMC) Supernova Remnant (SNR) J0450.4-7050, which we give the nicknam…
Diprotodon on the sky. The Large Galactic Supernova Remnant (SNR) G278.94+1.35
Miroslav D. FilipoviÄ, S. LazareviÄ, M. Araya +41
We present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNR) - that we name Diprotodon. While previously established as a Galact…
Low Mass Contact Binaries: Orbital Stability at Extreme Low Mass Ratios
Surjit S. Wadhwa, Natalia R. Landin, Bojan Arbutina +5
With the ever-increasing number of light curve solutions of contact binary systems increasing number of potential bright red nova progenitors are being reported. There remains, how…
Supernova remnants in clumpy medium: A model of hydrodynamic and radio synchrotron evolution
Petar KostiÄ, Bojan Arbutina, Branislav VukotiÄ +1
We present an analytical model of relation for supernova remnants (SNRs) evolving in a clumpy medium. The model and its approximations were developed using the hydrodynamic…
