A quark nova in the wake of a core-collapse supernova:a unifying model for long duration gamma-ray bursts and fast radio bursts被引量：1
《Research in Astronomy and Astrophysics》2020年第2期119-186,共68页Rachid Ouyed Denis Leahy Nico Koning 
supported by operating grants from the National Science and Engineering Research Council of Canada(NSERC)
By appealing to a quark nova(QN;the explosive transition of a neutron star to a quark star) in the wake of a core-collapse supernova(CCSN) explosion of a massive star,we develop a unified model for long duration gamma...

Quark nova model for fast radio bursts被引量：1
《Research in Astronomy and Astrophysics》2016年第5期87-98,共12页Zachary Shand Amir Ouyed Nico Koning Rachid Ouyed 
Fast radio bursts （FRBs） are puzzling, millisecond, energetic radio transients with no discernible source; observations show no counterparts in other frequency bands. The birth of a quark star from a parent neutron ...

Small glitches: the role of strange nuggets?
《Research in Astronomy and Astrophysics》2016年第3期91-98,共8页Xiao-Yu Lai Ren-Xin Xu 
supported by the National Natural Science Foundation of China (11203018);the West Light Foundation (XBBS-2014-23);the Science Project of Universities in Xinjiang (XJEDU2012S02);the Doctoral Science Foundation of Xinjiang University (BS120107)
Pulsar glitches, i.e. the sudden spin-ups of pulsars, have been detected for most known pulsars.The mechanism giving rise to this kind of phenomenon is uncertain, although a large data set has been built.In the framew...

Hints of a second explosion(a quark nova) in Cassiopeia A supernova
《Research in Astronomy and Astrophysics》2015年第4期483-500,共18页Rachid Ouyed Denis Leahy Nico Koning 
supported by operating grants from the National Science and Engineering Research Council of Canada (NSERC)
We show that the explosive transition of the neutron star （NS） to a quark star （QS） （a Quark Nova） in Cassiopeia A （Cas A） a few days following the supernova （SN） proper can account for several of the puzzli...

Quark-Novae Ia in the Hubble diagram: implications for dark energy被引量：1
《Research in Astronomy and Astrophysics》2014年第5期497-519,共23页Rachid Ouyed Nico Koning Denis Leahy Jan E.Staff Daniel T.Cassidy 
The accelerated expansion of the Universe was proposed through the use of Type-Ia supernovae （SNe） as standard candles. The standardization depends on an empirical correlation between the stretch/color and peak lumi...

SN 2009ip and SN 2010mc as dual-shock Quark-Novae
《Research in Astronomy and Astrophysics》2013年第12期1463-1470,共8页Rachid Ouyed Nico Koning Denis Leahy 
funded by the Natural Sciences and Engineering Research Council of Canada
In recent years a number of double-humped supernovae （SNe） have been discovered. This is a feature predicted by the dual-shock Quark-Nova （QN） model where an SN explosion is followed （a few days to a few weeks la...

Maximum mass of a hot neutron star with a quark core
《Research in Astronomy and Astrophysics》2011年第4期471-481,共11页Tayebeh Yazdizadeh Gholam Hossein Bordbar 
Financial support from the Research Council of Islamic Azad University
We have considered a hot neutron star with a quark core, a mixed phase of quark-hadron matter, and a hadronic matter crust and have determined the equation of state of the hadronic phase and the quark phase. We have t...

Influence of a scalar-isovector δ-meson field on the quark phase structure in neutron stars被引量：1
《Research in Astronomy and Astrophysics》2010年第12期1255-1264,共10页Grigor Bakhshi Alaverdyan 
supported by the Ministry of Education and Sciences of the Republic of Armenia under grant 2008-130
The deconfinement phase transition from hadronic matter to quark matter in the interior of compact stars is investigated. The hadronic phase is described in the framework of relativistic mean-field theory, where the s...

SWIFT J1749.4-2807: A neutron or quark star?
《Research in Astronomy and Astrophysics》2010年第9期815-820,共6页Jun-Wei Yu Ren-Xin Xu 
supported by the National Natural Science Foundation of China (Grant Nos. 10778611 and 10973002);the National Basic Research Program of China(Grant No. 2009CB824800)
We investigate a unique accreting millisecond pulsar with X-ray eclipses, SWIFT J1749.4-2807 （hereafter J1749）, and try to set limits on the binary system by various methods including use of the Roche lobe, the mass...
