Discovery of magnetic fields in the very young, massive stars W601 (NGC 6611) and OI 201 (NGC 2244)

, 2008
Context: Recent spectropolarimetric observations of Herbig Ae/Be stars have yielded new arguments in favour of a fossil origin for the magnetic fields of intermediate mass stars.

Aspects of Born-Infeld Theory and String/M-Theory [PDF]

, 2001
These notes provide a hopefully pedagogic introduction to Born-Infeld theory and some of its uses in String/M-Theory from the perspective of some-one interested in spacetime geometry.

D’un style scientifique dans certaines revues d’avant-garde (BLAST, The Signature, The Egoist, 1914-1915) [PDF]

Etudes de stylistique anglaise, 2011
A certains moments de l’histoire culturelle, l’artificielle frontiere entre style litteraire et langage scientifique tombe et laisse la place a un style hybride, propre a la mise en place d’une litterature-recherche. En Angleterre, les annees 1914-1915 sont un de ces moments.

3D-melting features of the irreversibility line in overdoped Bi$_2$Sr$_2$CuO$_6$ at ultra-low temperature and high magnetic field

, 1999
We have measured the irreversible magnetization of an overdoped Bi$_2$Sr$_2$CuO$_6$ single crystal up to B=28 T and down to T=60 mK, and extracted the irreversibility line $B_{\rm irr}(T)$: the data can be interpreted in the whole temperature range as a ...

Signature et travail d'attribution

Réseaux, 2004
A partir de l’etude des pratiques concretes de signature des publications scientifiques, cet article cherche a apprehender la fonction-auteur d’un point de vue pragmatique. L’objectif est de saisir la variete des elements que les chercheurs mobilisent et articulent dans le cours de leurs activites pour signer.

La signature scientifique

, 2004
La science apparaît généralement comme issue d'esprits solitaires et géniaux qui ont façonné leur époque. Cette représentation laisse cependant dans l'ombre le travail collectif qui soutient l'entreprise de production des connaissances. En suivant les chercheurs de plusieurs disciplines dans leurs activités concrètes, David Pontille étudie avec minutie

The spectral variability and magnetic field characteristics of the Of?p star HD 148937 [PDF]

, 2011
We report magnetic and spectroscopic observations and modeling of the Of?p star HD 148937 within the context of the MiMeS LP at the CFHT. Thirty-two high signal-to-noise ratio circularly polarised (Stokes V) spectra and 13 unpolarised (Stokes I) spectra ...

Discovery of two new bright magnetic B stars: i Car and Atlas

, 2015
The BRITE (BRIght Target Explorer) constellation of nano-satellites performs seismology of bright stars via high precision photometry. In this context, we initiated a high resolution, high signal-to-noise, high sensitivity, spectropolarimetric survey of ...
