Two populations of progenitors for Type Ia supernovae?
Open accessAbstract
We use recent observations of the evolution of the Type Ia supernova (SN Ia) rate with redshift, the dependence of the SN Ia rate on the colours of the parent galaxies, and the enhancement of the SN Ia rate in radio-loud early-type galaxies to derive on robust empirical grounds, the delay time distribution (DTD) between the formation of the progenitor star and its explosion as an SN.Our analysis finds: (i) delay times as long as 3-4 Gyr, derived from observations of SNe Ia at high redshift, cannot reproduce the dependence of the SN Ia rate on the colours and on the radio-luminosity of the parent galaxies, as observed in the local Universe;(ii) the comparison between observed SN rates and a grid of theoretical 'single-population' DTDs shows that only a few of them are possibly consistent with observations.The most successful models are all predicting a peak of SN explosions soon after star formation and an extended tail in the DTD, and can reproduce the data but only at a modest statistical confidence level; (iii) present data are best matched by a bimodal DTD, in which about 50 per cent of SNe Ia (dubbed 'prompt' SNe Ia) explode soon after their stellar birth, in a time of the order of 10 8 yr, while the remaining 50 per cent ('tardy' SNe Ia) have a much wider distribution, well described by an exponential function with a decay time of about 3 Gyr.The presence in the DTD of both a strong peak at early times and a prolonged exponential tail, coupled with the well-established bimodal distribution of the decay rate ( m 15 ) and the systematic difference observed in the expansion velocities of the ejecta of SNe Ia in ellipticals and spirals, suggests the existence of two classes of progenitors.We discuss the cosmological implications of this result and make simple predictions, which are testable with future instrumentation.

“The Hubble diagrams used to derive information on the cosmological parameters (Riess et al. 2004) are, up to now, mostly based on SNe at z< 1 and, therefore, are expected to be dominated by the “tardy” population.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
