“…The SCP and the High-Z Search Team used bright type Ia SNe as standard candles. These objects are thought to be thermonuclear explosions of carbon-oxide white dwarfs [50][51][52]. The correlation between the peak luminosity and the decline rate of the luminosity of the SNe [53][54][55][56] makes it possible to estimate its magnitude and with spectral information about the host one can determine its redshift.…”

We study the potential impact of improved future supernovae data on our understanding of the dark energy problem. We carefully examine the relative utility of different fitting functions that can be used to parameterize the dark energy models, and provide concrete reasons why a particular choice (based on a parameterization of the equation of state) is better in almost all cases. We discuss the details of a representative sample of dark energy models and show how future supernova observations could distinguish among these. As a specific example, we consider the proposed "SNAP" satellite which is planned to observe around 2000 supernovae. We show how a SNAP-class data set taken alone would be a powerful discriminator among a family of models that would be approximated by a constant equation of state for the most recent epoch of cosmic expansion. We show how this family includes most of the dark energy models proposed so far. We then show how an independent measurement of Ωm can allow SNAP to probe the evolution of the equation of state as well, allowing further discrimination among a larger class of proposed dark energy models. We study the impact of the satellite design parameters on this method to distinguish the models and compare SNAP to alternative measurements. We establish that if we exploit the full precision of SNAP it provides a very powerful probe.

Abstract. SuperNova Remnants (SNR) have been extensively studied in radio, X-rays and optical, but barely in the InfraRed (IR). From IRAS observations, SNR are known to be IR emitters, but the origin of the emission is difficult to assess because of the limited angular and spectral resolution of IRAS observations. ISO follow-up observations of the Cassiopeia-A SNR have shown that the mid-IR radiation from this remnant was dominated by thermal emission from silicate condensates made from SN material. These condensates constitute a probe which can provide unique information about element mixing inside a SN. In this paper, we present ISOCAM observations of the three other young SNR's known in our galaxy: the Kepler SNR, the Tycho SNR and the Crab Nebula. The emission observed from the Kepler SNR is dominated by dust thermal emission. The dust at the origin of the IR emission is circumstellar, not from SN condensates. "Astronomical" silicates, collisionally heated to a temperature of 107 K, can account for both the mid-IR ISO data and the IRAS data. The IR emission from Tycho is probably also emitted by circumstellar or interstellar dust. In order to reproduce both the mid-IR ISO data and the IRAS data, a model with two dust components, one at a temperature of 107 K and the other at 55 K, is needed. The mid-IR emission from the Crab is dominated by synchrotron radiation; no dust is detected.

“…Abundances in stellar populations in our galaxy and other galaxies are surveyed by Pagel, Edmunds & Kellermann (42), Mould (43), and van den Bergh (44). Abundances in supernova ej ecta and remnants are reviewed by Oke & Searle (45) and by Trimble (13,14). Other useful reviews include those on the chemical compositions of globular clusters (46,47) and on gamma-ray astronomy (48).…”

“…Significant early developments in nuclear astrophysics were reviewed by Cameron (1) and by Burbidge (2). There also exist a number of recent and more specialized reviews of explosive nucleosynthesis (3,4), of mechanisms of neutron-capture syn thesis (5)(6)(7), of the origin on he light elements (8,9), and of the related subjects of stellar evolution (10-12), supernovae (13,14), nucleocosmo chronology (15), and the chemical evolutiion of the galaxy (16,17). Excellent discussions of various aspects of nucleosynthesis theory may also be found in a number of books and conference proceedings (18-2 1).…”
