Research Progress on Rotating Detonations of Liquid Hydrocarbon Fuels [PDF]

Hangkong bingqi
Detonation waves propagate at velocities exceeding 1 000 m/s, enabling the reactants to complete reaction without significant expansion, thereby an isochoric combustion process can be achieved.

Spectral modelling of the "Super-Chandra" Type Ia SN 2009dc - testing a 2 M_sun white dwarf explosion model and alternatives [PDF]

, 2012
Extremely luminous, super-Chandrasekhar (SC) Type Ia Supernovae (SNe Ia) are as yet an unexplained phenomenon. We analyse a well-observed SN of this class, SN 2009dc, by modelling its photospheric spectra with a spectral synthesis code, using the ...
