Binary Evolution of Type Ia Supernovae
Observations of Type Ia supernovae (SN Ia) combined with modeling of dynamics, light curves and spectra continue to point to the difficult conclusion that SN Ia result from degenerate ignition in a carbon/oxygen white dwarf of the Chandrasekhar mass. Such a model accounts well for the “normal” SN Ia and for the observed dispersion exemplified by the light curve amplitude-shape relation. The cri...
متن کاملType Ia Supernovae
Type Ia Supernovae are in many aspects still enigmatic objects. Their observational and theoretical exploration is in full swing, but we still have plenty to learn about these explosions. Recent years have already witnessed a bonanza of supernova observations. The increased samples from dedicated searches have allowed the statistical investigation of Type Ia Supernovae as a class. The observati...
متن کاملthe impact of morphological awareness on the vocabulary development of the iranian efl students
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
15 صفحه اولThe impact of Type Ia supernova explosions on helium companions in the Chandrasekhar-mass explosion scenario
In the version of the single-degenerate scenario of Type Ia supernovae (SNe Ia) studied here, a carbon–oxygen white dwarf explodes close to the Chandrasekhar limit after accreting material from a non-degenerate helium (He) companion star. In the present study, we employ the Stellar GADGET code to perform threedimensional hydrodynamical simulations of the interaction of the SN Ia ejecta with the...
متن کاملThe Progenitors of Type Ia Supernovae
Type Ia supernovae (SNe Ia) occur in both old, passive galaxies and active, star-forming galaxies. This fact, coupled with the strong dependence of SN Ia rate on star formation rate, suggests that SNe Ia form from stars with a wide range of ages. Here we show that the rate of SN Ia explosions is about 1% of the stellar death rate, independent of star formation history. The dependence of SN Ia r...
