Identifier: http://hdl.handle.net/1959.14/291466
Description: We present the results of four, large scale, three-dimensional magnetohydrodynamics simulations of jets launched from a Keplerian accretion disk. The jets are followed from the source out to 90 AU, a ... More

Identifier: http://hdl.handle.net/1959.14/296266
Description: We show that, by appealing to a Quark-Nova (QN) in a tight binary system containing a massive neutron star and a CO white dwarf (WD), a Type Ia explosion could occur. The QN ejecta collides with the W ... More

Description: The R Coronae Borealis (RCB) stars are hydrogen-deficient, variable stars that are most likely the result of He-CO WD mergers. They display extremely low oxygen isotopic ratios, ¹⁶O/¹⁸O ≃ 1-10, ¹²C/¹³ ... More

Identifier: http://hdl.handle.net/1959.14/291458
Description: We explore the effect of large scale magnetic field on the formation of two-component jets in magnetohydrodynamic disk winds simulations. Our simulations show a one-component and two-component jets de ... More

Identifier: http://hdl.handle.net/1959.14/296729
Description: We show that several features reminiscent of short-hard gamma-ray bursts (GRBs) arise naturally when quark-novae (QNe) occur in low-mass X-ray binaries born with massive neutron stars (NS; ?1.6 M?) an ... More

Description: We propose a simple model explaining two outstanding astrophysical problems related to compact objects: (1) that of stars such as G87-7 (alias EG 50) that constitute a class of relatively low-mass whi ... More

Identifier: http://hdl.handle.net/1959.14/301455
Description: If a quark-nova occurs inside a collapsar, the interaction between the quark-nova ejecta (relativistic iron-rich chunks) and the collapsar envelope leads to features indicative of those observed in Ga ... More
