On the fraction of intermediate-mass close binaries that explode as type-Ia supernovae [PDF]

, 2007
Type-Ia supernovae (SNe-Ia) are thought to result from a thermonuclear runaway in white dwarfs (WDs) that approach the Chandrasekhar limit, either through accretion from a companion or a merger with another WD.

The Hubble Space Telescope Cluster Supernova Survey: V. Improving the Dark Energy Constraints Above z>1 and Building an Early-Type-Hosted Supernova Sample [PDF]

, 2011
We present ACS, NICMOS, and Keck AO-assisted photometry of 20 Type Ia supernovae SNe Ia from the HST Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval 0.623 < z < 1.415.

L’IA, le brin d’herbe, la caresse et le regard

Interfaces Numériques, 2020
L’IA est souvent présentée comme un modèle devenu un concurrent de l’intelligence humaine. Mais si on la caractérise qu’elle est une manière artificielle de résoudre des problèmes qui requièrent de la part des humains de l’intelligence, rien n’implique ...

The Evolution of the Type Ia Supernova Luminosity Function [PDF]

, 2017
Type Ia supernovae (SNe Ia) exhibit a wide diversity of peak luminosities and light curve shapes: the faintest SNe Ia are 10 times less luminous and evolve more rapidly than the brightest SNe Ia.

Lifelong self-education in a sociotechincal context

Contextos Educativos: Revista de Educación, 2020
Permanent education is a process of self-construction based on the pedagogical principles of educability, educativity and personal autonomy. The process of human construction implies a process of lifelong and lifewide learning and training in order to ...

Evidence of Environmental Dependencies of Type Ia Supernovae from the Nearby Supernova Factory indicated by Local H{\alpha} [PDF]

, 2013
(Abridged) We study the host galaxy regions in close proximity to Type Ia supernovae (SNe Ia) to analyze relations between the properties of SN Ia events and environments most similar to where their progenitors formed. We focus on local H\alpha\ emission

Type Ia Supernovae [PDF]

Symposium - International Astronomical Union, 1992
Spectral calculations show that a model based on the thermonuclear explosion of a degenerate carbon/oxygen white dwarf provides excellent agreement with observations of Type Ia supernovae. Identification of suitable evolutionary progenitors remains a severe problem. General problems with estimation of supernova rates are outlined and the origin of Type
