New class of laboratory astrophysics experiments : application to accretion processes around neutron stars

Autor: Tranchant, Victor

Neutron stars are subject to intense X-ray bursts, interacting with their surrounding accretion disks. This complex process has yet to be completely understood. In given conditions, this strong radiation leads to the propagation of radiatively driven

The Wirst part of the thesis focuses on the relativistic, two-body problem in the context of general relativity. More precisely, we derive a variational identity known as the ``First Law of Mechanics" that relates physical parameters of a binary syst

Corrections général-relativistes à l’émission radio et haute énergie des pulsars

Autor: Giraud, Quentin

Neutron stars are very dense objects, denser than an atomic nucleus, formed during a supernova. A typical neutron star concentrates a mass superior to the one of the Sun in its diameter of around twenty kilometers. According to general relativity, wh

Émission multi-longueurs d'onde du jet compact de MAXI J1836-194

Relativistic jets, although ubiquitous in the Universe, have not yet delivered all their secrets. On the contrary, some of the most fundamental questions of the field remain unanswered. The ejection mechanism at the origin of the emission is still un

Study of the high energy emission of accreting compact objects with SPI/INTEGRAL

Autor: Droulans, Robert

Publikováno v: Planète et Univers [physics]. Université Paul Sabatier-Toulouse III, 2011. Français

The study of the high energy emission is essential for understanding the radiative processes inherent to accretion flows onto compact objects (black holes and neutron stars). The X/-ray continuum of these systems is successfully interpreted in terms
