Circumbinary Discs as the Origin of Circumstellar Material around Interacting H-poor Supernovae and Fast Blue Optical Transients
Ryotaro Chiba, Semih Tuna, Brian D. Metzger +1
Around 10 % of hydrogen-poor supernovae explode inside compact ( cm), massive () circumstellar material (CSM), signalling an episode of e…
Super-Eddington Chimneys: On the Cooling Evolution of Tidal Disruption Event Envelopes
Semih Tuna, Brian D. Metzger, Yan-Fei Jiang +1
The formation of a compact accretion disk following a tidal disruption event (TDE) requires that the shocked stellar debris cool efficiently as it settles toward the black hole. Wh…
Nature of phase transitions and metastability in scalar-tensor theories
Kıvanç Ä°. Ãnlütürk, Semih Tuna, OÄuzhan K. Yamak +1
Compact stars above a critical stellar mass develop large scalar fields in some scalar-tensor theories. This scenario, called spontaneous scalarization, has been an intense topic o…
Time-Dependent Radiation Transport Simulations of Infrared Echoes from Dust-Shrouded Luminous Transients
Semih Tuna, Brian D. Metzger, Yan-Fei Jiang +1
A wide range of stellar explosions, including supernovae (SNe), tidal disruption events (TDE), and fast blue optical transients (FBOT), can occur in dusty environments initially op…
